TECHNICAL BULLETIN #0428B 04-04-90 ============================================================================= PREMIUM/286 AND 386 THIRD FLOPPY SUPPORT The following summarizes installation considerations for a third floppy device in AST Premium Computers: PREMIUM/286 HARDWARE CONSIDERATIONS PREMIUM/286 systems equipped with part number 202143-003 or 202143-004 system boards include embedded diskette drive controller circuitry that allows support for a third floppy device. The third floppy is connected to the 34 pin connector on the system board with an additional floppy drive controller cable (AST part number 220085-001). The cable is attached to the third floppy device and the 34 pin connector J20 on the system board. PREMIUM/386 HARDWARE CONSIDERATIONS All PREMIUM/386 system boards are built with embedded third floppy diskette control circuitry. The same cable (AST part number 220085-001) is required to install the third floppy device. This cable connects to the P4 connector on the 386 system board. SOFTWARE CONSIDERATIONS Because the third floppy device is not directly recognized by the system BIOS, two device drivers, DRIVER.SYS and ASTDSK.DRV, must be inserted into the CONFIG.SYS file. DRIVER.SYS is provided with MS-DOS Version 3.3 Release 1.3 and ASTDSK.DRV is provided on the AST Utilities diskette shipped with all PREMIUM systems. DOS VERSIONS AST recommends and supports the use of AST MS-DOS Version 3.3 Release 1.3. For best results, users of earlier DOS versions should upgrade to Version 3.3 Release 1.3. Contact your local AST Service Center for additional information. INSTALLATION The AST Utilities Diskette provides menu-driven automatic installation of the third floppy device drivers into the CONFIG.SYS file. The following are the configuration commands for each of the possible hardware combinations. The commands listed below are supported under DOS Version 3.2 and 3.3 unless otherwise noted: For 360 KB drive (5.25-inch diskettes) DEVICE=C:\DOS\ASTDSK.DRV 0 DEVICE=C:\DOS\DRIVER.SYS /D:2 /F:0 For 720 KB drive (3.5-inch diskettes) DEVICE=C:\DOS\ASTDSK.DRV 2 DEVICE=C:\DOS\DRIVER.SYS /D:2 /F:2 For 1.2 MB drive (5.25-inch diskettes) DEVICE=C:\DOS\ASTDSK.DRV 1 DEVICE=C:\DOS\DRIVER.SYS /D:2 /F:1 /S:15 For 1.44 MB drive (3.5-inch diskettes) DEVICE=C:\DOS\ASTDSK.DRV 3 DEVICE=C:\DOS\DRIVER.SYS /D:2 /F:7 /S:18 (use /F:3 for DOS 3.2) ============================================================================= AST RESEARCH, INC.

TECHNICAL BULLETIN #0457A 02-21-90 ============================================================================= AST-3270/FTS-C FUNCTIONAL ISSUES AST Product Marketing has reviewed all of the open issues relating to this product. They have made the decision that the following issues will not be resolved. This product has been discontinued by AST. No further enhancements will be made to this product. These issues are: - User cannot upload files to a TSO host properly. If the customer tries to upload information to an existing partitioned data set and a non- existing member, he receives the error message "UNABLE TO TERMINATE INPUT MODE". If neither the data set nor the corresponding member exist on the host, the file transfer will work for the first member only. (PR#A32006) - User cannot transmit more than one file to the host during a file transfer session. The first file transfers okay, but after entering the second file name, the error message from the host "IKJ56712I- INVALID KEYWORD, LISTDS IKJ560703A-RE-ENTER" is displayed. The file transfer software displays the message "Unable to open dataset". (PR#A32007) - With FTS-C version 1.31, user is reporting intermittent problems when attempting to upload files of greater than 64K in size. The host is an IBM 4381 running CMS under VM/SP release 5. When FTS-C attempts to close the uploaded file, the error message "NON-RECOVERABLE HOST ERROR, FTS ABORTED" is displayed. (PR#A32011) - When attempting file transfer on an MVS/XA TSO/ACF2 host, the error message "Unable to list TSO profile" message is received when the file upload is commenced. (PR#A32012) - When performing file uploads to the host, user says that FTS-C sends screens of data faster than the host can process them. The software does wait for an acknowledgement from the host that the first screen was received, but does not wait to send ensuing screens of data. The host is operating under MVS/XA TSO. (PR#A32013) - When using FTS-C software with a mainframe configured with TSO/E version 3.0, downloading of files does not occur correctly. Parts of records are either truncated or missing altogether. Problem occurs with files of larger than 10K in size. (PR#A32008) - "Unrecoverable host errors" occur on a host operating under VM release 5 with a multi-session manager called "VTERM" installed. Errors occur at end of file transfer session as files are being downloaded. (PR#A32014) - Packed record formats are not supported with FTS-C. When the software encounters the LRECL parameter value of "1024" (for packed files) the error message "record length greater than 255" is generated. (PR#A32015) ============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0499A 05/16/90 ============================================================================= AST-5250 ASYNC DIAL-UP FUNCTIONAL ISSUES AST Data Comm Product Marketing has reviewed all aspects of the following functional issues relating to the 5250 Async Dial-up product (part number 500307-001). They have made the determination that these issues will not be resolved for this product. These issues are as follows: - The user is sharing one session between the master and slave systems. This device is also used as a sub-console. When a change is made to the screen of the slave, such as a change of menu, the screen takes about 30 seconds to completely refresh on the slave. (PR#A46011) - A job sent from the IBM System/36 to a printer attached to an Async Dial-up slave may appear to operate very slowly. The printer will print two lines, pause, then print two more lines. The Async Dial-up product is however, operating as designed. (PR#A46015) ============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0500E 11-14-90 ============================================================================= AST-5251/11 ENHANCED FUNCTIONAL ISSUES AST Data Comm Product Marketing has reviewed all aspects of the following functional issues relating to the 5251/11 Enhanced product (part number 500417-XXX). They have made the determination that these issues will not be resolved for this product. These issues are as follows: - An application from IBM for use on the IBM AS/400, called "AS/400 OFFICE", will not operate when used on a terminal which is configured using the Enhanced emulation software. When the program is loaded, data on the screen is garbled. (PR#A45129) - The 5251/11 Enhanced board does not function correctly when installed in a system with an Orchid "Tiny Turbo" card. The 5251/11 software reports various errors such as "Internal stack overflow" and "Unidentified error". (PR#A45059) - The user is printing a job sent from the System 36 to a printer attached to the PC which is emulating an IBM system printer. If during the job the printer is powered down, upon re-starting the printer the rest of the printed data is unintelligible. (PR#A45092) - The utility ASTKBD.EXE may corrupt the AST5251.KBD data file, if changes are made to the keyboard configuration and the changes are written over the existing AST5251.KBD file. (PR#A45081) - The Enhanced card does not appear to operate correctly when installed on a line with the IBM 3197 terminal. If the Enhanced card is the last device on the line, and the IBM 3197 terminals in front of it are operating then the system with the Enhanced card in it may lock up. (PR#A45101) - The 5251/11 Enhanced product does not operate in a Toshiba 5100 PC. The user gets a blank sign-on screen with "SA" highlighted. The emulation does not work at any system speed. (PR#A45036) - The keyboard mapping of the 11/Enhanced product does not work correctly on the Wyse Models 2200 and 2214. The keypad, cursor arrow keys, and right "control" key do not operate as they are supposed to. (PR#A45057) - Emulation does not function correctly in the Commodore PC-10 compatible computer. System locks up when more than one error message is received from the System 34. (PR#A45063) - The 11/Enhanced product does not work correctly in the DTK XT-clone system. It may be necessary to disable the PC's clock to allow emulation to operate. (PR#A45113) - With 11/Enhanced board operating in a Unisys PC with a Persyst CGA adapter, there is more than the normal amount of "snow" on the emulation screen. The "no snow" option in the configuration program does not have any affect on the problem. (PR#A45118) - The 5251/11 Enhanced software does not support the Keytronics 122-key keyboard. The right hand "Control" key and the PC "Enter key" issue the same scan code in DOS. For this reason these two keys cannot be mapped to different functions by the AST emulation software. (PR#A45116) - When running emulation program in EGA mode, all screen attributes that should appear as yellow on the screen actually appear as a shade of brown. (PR#A45168) ============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0513F 11-15-90 ============================================================================= AST-5251/11 FUNCTIONAL ISSUES AST Data Comm Product Marketing has reviewed all aspects of the following functional issues relating to the 5251/11 product (part number 500222-XXX). They have made the determination that these issues will not be resolved for this product. These issues are as follows: - The user is attempting to use virtual print, to print a DisplayWrite 4 document. When trying to print to a 5219 printer, bold character codes are being interpreted as blank spaces. (PR#A00147) - User has 5251/11 cards in IBM XT's and XT clones. User has found that after signing on the System 38, the systems with these cards will randomly lock up. Removing the hard disk and controller seems to resolve the problem. (PR#A00154) - User has a VGA display adapter installed in conjunction with the 5251/11 card. During a cold boot of the system, the 5251/11 KERNEL program fails to load, with an error code "5". However, during a warm boot KERNEL successfully loads. (PR#A00181) - The use of the Hewlett Packard LaserJet II is not fully supported with the 5251/11 software. This means that the LaserJet II cannot be used to emulate all functions of a true IBM System 3X printer when attached to a PC running the AST emulation program. (PR#A00188) - The 5251/11 adapter does not operate in a Magitronics 12MHz AT clone. When emulation software is executed, only a blank sign-on screen appears. The "SA" is not highlighted in the status area, and the cursor remains in the upper left-hand corner. (PR#A00185) - 5251/11 does not support Epson LQ850 and LQ1050 printers because Vertical Motion Index units of n/60 are not recognized by the emulation software. (PR#A00192) - Under 5251/11 emulation, a Hewlett Packard LaserJet II printer is configured as an IBM 5224 Model 1 printer. When printing any system 36 application, one or more blank pages (depending on the application) are ejected after every form feed, which is not normal operation for this type of printer. (PR#A00171 and PR#A00196) - The 5251/11 emulation is installed in an "AT" type system which has Award 3.03 BIOS. When loading the emulation software, an error code "2" or "3" is generated, and software cannot be executed. (PR#A00189) - Displaywrite/36 documents do not print correctly through 5251/11 emulation. The PC printer emulating a host printer does not recognize the right margins of the Displaywrite/36 document. Also, when printing a legal (8.5 by 14 inch) document, the PC printer does a form feed at 11 inches. (PR#A00150) - The "End" (number 122) key on a 122-key keyboard will not remap to another function in "shifted" or "caps lock" mode. The same key can be remapped to another function in "lower case" mode. (PR#A00194) ============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0547A 03-22-90 ============================================================================= 5250 FILE TRANSFER ON THE IBM AS/400 These requirements must be met before using AST 5250 File Transfer software on the IBM AS/400: - The AS/400 library named QSYS38 provides the functions needed for the System/38 environment. This library must be present and added to a user's library list before using the AST 5250 file transfer software. Without these functions the software will fail to initialize and generate function check errors. - A period occurring in the name of a file which is to be either uploaded to or downloaded from the AS/400 will cause the following error to occur: ERROR 30 S/3X FILE(S) NOT FOUND Remove any periods found in file names before attempting to transfer on the AS/400. It should be noted that periods are allowed in files transferred on the IBM System/36. ============================================================================= AST RESEARCH, INC.

When signing on to a subsequent session with the same workstation ID, the following parameters will have been deleted (zeroed): LIBRARY SYSLIST DEVICE FORMS LINES PER PAGE The KERNEL.EXE program can be patched to ensure that this does not happen. The patch outlined in this document uses NORTON UTILITIES, but can be modified to fit other debugging programs. To alter KERNEL.EXE using NORTON UTILITIES do the following: 1. Enter the NORTON UTILITIES program. From the "Main Menu" choose EXPLORE DISK. From "Menu 1" choose the appropriate item. 2. From "Menu 1.1" change directory or drive designation as necessary to make sure that KERNEL.EXE (found on disk 1 of the emulation software) is available to the program. Next, choose the FILE option "Menu 1.1.3" and highlight KERNEL.EXE. 3. Return to "Menu 1" and take the SEARCH option, then from "Menu 1.4" choose TEXT TO SEARCH. The next screen has two fields. Tab to the HEX field and enter the hex string "B9 0B 00". Return to the previous menu and choose START SEARCH. The program will display a message that the string has been found. 4. Move the cursor over the hex digits "0B" and type in "09" over them and press . A screen will appear with choices of action to take. Choose WRITE CHANGE TO DISK. 5. When this operation is complete, repeat Step 3, with the exception of the hex data to enter. This time, the string to enter is "B9 68 0B". 6. After the text is found, move the cursor over the "0B" and type in "09" over the top of these digits. Repeat the process of saving the new data to disk. 7. Press to return to the "Main Menu" and exit NORTON UTILITIES. Be sure to copy the "patched" KERNEL.EXE to the working directory or disk to be used when running emulation. 8. Enter Model 12 emulation and verify that the changes have the correct affect. To alter KERNEL.EXE using the MS-DOS DEBUG program, do the following: 1. Make sure the DEBUG program is available, then type the following: COPY KERNEL.EXE KERNEL.FIX {copy the kernel} DEBUG KERNEL.FIX {make sure DEBUG is available} -S 0 FFFE B9 0B 00 {search for the opcodes} xxxx:yyyy {location of opcodes from DEBUG} -E xxxx:yyyy {enter editing mode} xxxx:yyyy B9. 0B.09{change 0B to 09 only} -S 0 FFFE B9 68 0B {search for next string} aaaa:zzzz {DEBUG prints address on screen} -E aaaa:zzzz {edit address supplied in previous step} aaaa:zzzz B9. 68. {change 0B to 09} 0B.09 -W {write the changes out to disk} -Q {quit the debugger} 2. If you would like to save a copy of the original kernel, type: REN KERNEL.EXE KERNEL.OLD REN KERNEL.FIX KERNEL.EXE If you do not want to save a copy of the original kernel, type: COPY KERNEL.FIX KERNEL.EXE DEL KERNEL.FIX These changes should be performed only with those copies of 5251/12 emulation that connect to the System/34.

TECHNICAL BULLETIN #0599 01-15-90 ============================================================================= AST PRODUCTS AND NOVELL NETWARE/386 The following items should be considered prior to installing Novell Netware/386: 1. The AST 3G PLUS and 3G PLUS II display adapters are not compatible with Netware/386. A different video card should be used, (such as the AST VGA or VGA PLUS). Since the 3G PLUS and 3G PLUS II are no longer manufactured, no fixes are planned for this problem. 2. When installing Netware/386 on an AST Premium/386C, the motherboard must be equipped with the -007 or above keyboard controller chip. This chip is socketed at location U103 on the motherboard and is identified with AST part number 107210-007. If this chip has a part number of 107210-005 or below, Netware/386 will not run. To obtain the correct keyboard controller chip revision, it is necessary to install an AST Premium/386-386C BIOS Upgrade Kit, AST P/N 500702-001. Contact your nearest AST Authorized Service Center for additional information. ============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0600 01-16-90 ============================================================================= 486/25 SETUP: COPROCESSOR INSTALLATION The description of screen number two of the ASTSETUP program in the 486/25 User's manual (p/n 001054-001 A) is different than the actual screen as it appears when ASTSETUP is run. On page 3-10 of the manual, there are two fields described relating to installation of a math coprocessor. One field is labeled "Math Coprocessor", the other "Math Coprocessor Type". However, on screen number two of the setup utility (release 1.00 of the 486/25 BIOS, p/n's 107000-690A and -691A) there is only one field present. It is labeled "Math Coprocessor Type". This field will only display one of two entries - "None" and "Weitek" (for the Weitek 4167). The 486/25 will automatically sense that a Weitek coprocessor is installed, and display accordingly, otherwise the field will read "None". ============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0601 01-19-90 ============================================================================= REMOVAL OF NON-DOS PARTITIONS FROM AT EMBEDDED DRIVES Because AST does not recommended using HDFORMAT (the low level formatting program supplied with AST computers) on AST-supplied AT Embedded hard drives, the removal of non-DOS partitions created on these drives can be accomplished using either of the following methods: 1. Remove the partition using the utilities supplied with the non-DOS operating system that installed the partition in the first place. 2. Remove the partition with a low-level format using a hard disk utilities program, such as On Track's "Disk Manager". ============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0602A 02-26-90 ============================================================================= XFORMER/286 COMPATIBILITY ISSUES AST EPM Product Marketing has considered all aspects of the following compatibility issues regarding the Xformer/286 (part number 202204-XXX). They have determined that AST will not attempt to establish the cause of the incompatibilities. These issues are: - A conflict exists between the AST Rampage/286 card and an SMC Arcnet PC250 card when the two are installed together in the Xformer/286. The system intermittently re-boots when a DOS command is entered from the keyboard. (PR#B33016) - The Xformer/286 intermittently loses setup information stored in CMOS. (PR#B33020) - After a "warm boot" the and arrow keys (on an enhanced keyboard) perform the function of changing system speed. This function is normally performed by using the - key sequence in conjunction with either the or keys. (PR#B33028) ============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0603A 02-27-90 ============================================================================= INSTALLING AST 3G PRODUCTS WITH OS/2 EXTENDED EDITION To insure compatibility with AST OS/2 Extended Edition 1.10, the AST 3G Plus (part number 202104-XXX) must have BIOS revision level "F" or above installed. The BIOS chip is located at U29. The revision level can be read directly from the label on the BIOS chip. Likewise, the AST 3G Plus II adapter (part number 202161-XXX) must have BIOS revision "D" or above installed. The BIOS chip on the 3G Plus II is located at U10. In addition, Hercules emulation must be disabled for both of the above video adapters when used with OS/2 Extended Edition. Hercules emulation generates non-maskable interrupts which conflict with OS/2 initialization. Consult the respective 3G adapter User's manual for the method of disabling Hercules emulation. ============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0604 01-29-90 ============================================================================= AST DOS 3.3 AND IBM PC SUPPORT INSTALL UTILITY The IBM AS/400 PC Support Install utility Release 1.02 Level 00 does not work on a PC which uses MS-DOS instead of PC-DOS. The following is a method that may be used to install the AS/400 PC Support software on an MS-DOS system that has an AT-style bus and uses the IBM 5250 Enhanced Adapter card. If using an Enhanced AST-5251/11, Enhanced AST-5251/11 Plus or Enhanced AST- 5251/11A Plus Adapter card, use the AST Twinax Adapter Handler for AS/400 PC Support and its documentation. This method assumes that the user is using two 360k diskettes on which to install the PC Support system. If the user is using a hard disk or diskettes with higher capacity, all of the files may be put on the single disk in a single subdirectory. 1. FORMAT THE DISKS: Format the first working disk and install the operating system on it. Label the disk AS/400 PC SUPPORT, FIRST WORKING DISK. An example of the command to use for formatting: format a: /s Format the second disk without the operating system. Label the disk AS/400 PC SUPPORT, SECOND WORKING DISK. An example of the command to use for formatting: format a: Copy COMMAND.COM onto the second disk root directory. 2. CREATE CONFIG.SYS: Using a text editor such as edlin, create a CONFIG.SYS file in the root directory on the first working disk which contains the following lines: device=\pcs\eimpcs.sys device=\pcs\ecyddx.sys device=\pcs\fsdd.sys files=15 3. CREATE PCS SUBDIRECTORY: On each working disk, create a PCS subdirectory using the command: mkdir \PCS 4. CREATE CONFIG.PCS: This file is used by the PC Support system to get information on the "name" of the PC, the "name" of the host AS/400 and the station address that should be used to communicate to the AS/400. The CONFIG.PCS file should be created with a text editor and placed in the PCS subdirectory of the second working disk. Typical contents are: RTYP 5250 RTLN APPN.Pcname EMLI Hostname,2 Pcname is the name of the PC you are using. Each PC connected to the AS/400 via PC Support should have a different name. Hostname is the name that was given to the host AS/400 when setting up the system. The number 2 indicates station address 2 is to be used to connect to the AS/400. This number ranges from 0 to 6 and should be unique for each station on a single twinax cable. 5. CREATE PCS.BAT FILE: This batch file is used to start the AS/400 PC Support system. Using a text editor create a pcs.bat file on the second working disk in the root directory which contains the following lines: [d:]* \PCS\E5250AH [d:]* \PCS\STARTRTR \PCS\CONFIG.PCS [d:]* \PCS\FSPC ASSIGN I: QIWSFLR I:PCSUPDT I:\ \PCS I:STARTMSG \PCS\CONFIG.PCS I:VPRT I:WSF /T IF ERRORLEVEL 20 GOTO DONE IF NOT ERRORLEVEL 10 GOTO WORKSTRT I:STARTWSF 1 :WORKSTRT I:PCO \PCS\CONFIG.PCS :DONE * Drive letter should designate drive where PCS subdirectory exists. This batch file may be customized to start only those features of PC Support that are desired. 6. COPY THE FILES FROM THE IBM DISTRIBUTION DISKS TO WORKING DISKS: Copy the files from the IBM Distribution Disks to the subdirectory \PCS on the working disks using the DOS copy command. For example: copy a:eimpcs.sys b:\pcs\eimpcs.sys From IBM Distribution Disk 1 to working disk 1 subdirectory \PCS copy: EIMPCS.SYS ECYDDX.SYS FSDD.SYS From IBM Distribution Disk 1 to working disk 2 subdirectory \PCS copy: E5250AH.COM FSPC.EXE FSPC.HLP XXRTRS.MRI From IBM Distribution Disk 2 to working disk 2 subdirectory \PCS copy: STARTRTR.EXE E5250RTR.EXE STOPRTR.EXE 7. REBOOT USING FIRST WORKING DISK: Insert the first working disk in drive A and reboot your computer. 8. START PC SUPPORT: Insert the second working disk in the default drive or set the default drive to the drive which contains the second working disk. Type PCS to invoke the PCS.BAT batch file and start PC Support. Steps 7 and 8 may now be repeated to run AS/400 PC Support at future times. ============================================================================= AST RESEARCH, INC.

It allows extended memory on the board to be configured as expanded memory in an 80386 based system. Microsoft Excel version 2.1 has the capability to utilize expanded memory. Excel, however, will not recognize memory allocated as expanded memory by certain versions of ASTEMM.SYS. To give Excel version 2.1 the use of expanded memory which is allocated by ASTEMM.SYS, version 4.06 or above of ASTEMM.SYS must be used. ============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0609A 02-01-90 ============================================================================= REMM.SYS VERSION 4.50 The following incompatibilities and hardware conflicts can be resolved through the use of REMM.SYS version 4.50 (or later): - The application "SAS" (version 6.03), which is a statistical package, cannot access expanded memory. - A conflict between REMM.SYS and a NEC GB-1 video adapter. Data errors occur while REMM.SYS is initializing memory if both are installed in the system. - In a system which has a Hercules Plus card installed, WordPerfect does not work correctly when REMM.SYS is present. The symptom exhibited is that there is no cursor present on the screen when WordPerfect is executed. - A word processing program from SAMNA does not operate when REMM.SYS is installed. The system locks up as the word processor is executed. - With a Video Seven "VRAM" VGA adapter installed in the system, REMM.SYS would generate the error message "NO Logical Memory Pages Found", then abort. NOTE: The Video Seven adapter runs in 16 bit mode, so the parameter "/M=5F" should be added to the REMM.SYS command line in the CONFIG.SYS file. ============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0610 02-07-90 ============================================================================= SERIAL PORT PARITY ERRORS Under certain circumstances, the serial ports on some Premium computers may exhibit parity errors during serial data transmission. The problem manifests itself as a bad parity bit when transmitting data with 8 Bits, 1 Stop Bit and Even Parity.

TECHNICAL BULLETIN #0615 03-02-90 ============================================================================= CONFIGURING FLOPPY DRIVES FOR AST SYSTEMS To insure proper installation of a floppy drive into an AST computer system, make sure the following conditions are met. The AST diskette drive specification calls for "frame" ground to be connected to "logic" ground. On many floppy drives this is accomplished by the correct placement of a jumper on the drive's control electronics printed circuit board. Refer to the instructions included with the drive to verify correct placement of the grounding jumper. In addition, the grounding strap from the power supply should be attached to the drive's metal frame during installation. It should be noted that it may be necessary to move the ground strap from it's normal position on the Premium computer's chassis to a position where the ground connection on the floppy drive frame can be accessed. ============================================================================= AST RESEARCH, INC.

TECHNICAL BULLETIN #0619 03-20-90 ============================================================================= RUNNING COMPATIBILITY TESTS ON THE VGA PLUS The IBM VGA standard supports two methods of addressing monochrome and color displays: - The VGA included on PS/2 systems allows software to address both monochrome and color monitors at the same time with no restrictions (colors in monochrome appear as shades of gray). - The VGA adapter for AT type systems allows software to address either color monitors or monochrome monitors, but not both. The AST VGA Plus adapter is compatible with the VGA standard for the IBM AT adapter. This means that software used with the VGA Plus will only address a color display in color mode or a monochrome display in monochrome mode. Switching between display modes is accomplished through the use of the ASTVGA.EXE utility included with the VGA Plus utilities. The adapter, by design, will not pass diagnostics written to test VGA monochrome modes while the adapter is in VGA color mode. In particular, tests from "PC Magazine" issue commands which are meant to test a PS/2 type adapter and will fail on an adapter which follows the IBM AT adapter standard. This is normal operation for any VGA adapter which follows the IBM AT VGA adapter standard. Some compatibility tests may also fail because of a hardware conflict. The IBM AT VGA adapter supports the use of hardware interrupt IRQ2. However, the AST VGA Plus adapter does not. The VGA Plus will fail tests such as one from "PC Tech Journal" (test 13) which attempts to use IRQ2. ============================================================================= AST RESEARCH, INC.

TECHNICAL BULLETIN #0622 04-12-90 ============================================================================= SOFTWARE TOOLWORKS PROGRAMS AND PREMIUM COMPUTERS Problems have been reported when attempting to install Chessmaster 2100, Gin King/Cribbage King and Mavis Beacon Typing Tutor from the Software Toolworks company on AST Premium computers. The problem is caused by a conflict between Software Toolworks' installation program and the Premium computer's Shadow Ram feature. The Shadow Ram feature determines whether or not the system BIOS is copied to and executed from 32-bit RAM rather than 16-bit ROM during system processing. To resolve problems encountered during installation of Software Toolworks' programs, disable the Premium computer's Shadow Ram feature before starting the program's installation procedure. After completing installation, the Shadow Ram feature may be enabled because the conflict occurs during installation only and does not occur when running the program. The User's Manual supplied with each AST computer provides complete information on the Shadow Ram option. ============================================================================== AST RESEARCH, INC.

TECHNICAL BULLETIN #0625A 05/16/90 ============================================================================= AST 5250 GATEWAY COMPATIBILITY ISSUES Data Comm Product Marketing has considered all aspects of the following compatibility issues relating to the AST 5250 Gateway product (part number 500399-001). They have made the determination that these issues will not be resolved for this product. These issues are as follows: - The Gateway software will not function correctly when used on a DCA 10 Net LAN. The master and one slave will operate as a Gateway master and slave. However, when a third node on the LAN tries to access one of these two (e.g., a workstation accessing a server), then all three systems lock up, requiring a cold boot of all the systems. (PR#A41040) - Under Novell Netware version 2.12 software, IBM Token Ring boards exhibit failures while running Gateway emulation. Any of the slaves on the gateway will intermittently lock up or lose communication to the master PC. (PR#A41044) - When running under Gateway emulation, a print job sent to a printer attached to a server using the Novell "CAPTURE" command does not print correctly. Print data is shifted 3 or 4 columns in from the left margin. (PR#A41051) - Under a configuration where the slaves are communicating with the master remotely via G-Remote Bridge (from Gateway Communications), the response time for communication between slaves and master is very slow. (PR#A41052) - The 5250 Gateway does not support an environment which uses IBM Token Ring cards running with Novell Netware 286 (all versions). When operating under this type of environment, the slaves will lose communication with the Gateway master, and require a reset to continue the session.

TECHNICAL BULLETIN #0627 05/31/90 ============================================================================= INCOMPATIBLE DRAMS FOR RAMPAGEPLUS/286 Memory errors in a system which can be attributed to a RampagePlus/286 (part number 202349-001) being present may actually be caused by the use of certain manufacturers DRAM chips on the SIMMS present on the board. SIMMS which are used to upgrade memory on the RampagePlus/286 have AST part numbers 202279-002, 202280-002, and 202320-002. The DRAM chips which are incompatible with the RampagePlus/286 are manufactured by Motorola and Toshiba. The memory chips are of the 256KX4 type (three IC's present on the SIMMS). If memory errors or system lock-ups are being experienced, remove all SIMMS containing these DRAM chips and substitute with other SIMMS. Other manufacturers DRAM chips approved for the RampagePlus/286 are: Mitsubishi M5M44256AP-10 NEC UPD4242556C-10 OKI MSM514256-10RS TI TMS44C256-10N ============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0628 06-29-90 ============================================================================= USE OF ASTEMM.SYS WITH SUPERCALC 5 The application SuperCalc 5 has the ability to access expanded memory. However, SuperCalc 5 will have problems accessing emulated expanded memory created by certain versions of the driver ASTEMM.SYS. ASTEMM.SYS version 4.08 (or above) must be used to allow SuperCalc 5 to function properly. Earlier versions of ASTEMM.SYS cannot be guaranteed to perform satisfactorily with this application.  ============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0629 06-27-90 ============================================================================= AUTOSENSING OPERATION OF THE VGA PLUS When the AST VGA Plus (part number 202262-003) is configured to operate in 16 bit mode (switch position "two" = ON) the entire memory address range from C0000h to DFFFFh is in 16 bit mode for all system memory accesses. This is due to the design of the IBM AT standard I/O bus. This means that an 8 bit adapter which is configured to reside in this region will not be recognized by the system. Version 3.0 of the VGA Plus BIOS (part numbers 107000-682 and 107000-683) has the ability to detect the standard IBM ROM signature "AA 55". If, when the system is being initialized, the VGA BIOS detects this signature anywhere in the 128K range where it resides, the VGA Plus will switch back to eight bit operation to avoid conflicts. The BIOS cannot detect the presence of RAM (e.g., shared memory) on an adapter, however. In order for adapters which have this type of memory (e.g., IBM Token Ring II adapters) to be configured to operate in this address range, the VGA Plus has to be manually switched back to 8 bit operation (switch position "two" = OFF) to avoid conflicts.  ============================================================================= AST RESEARCH, INC.

TECHNICAL BULLETIN #0634 08-23-90 ============================================================================= AST SHADOW BIOS MEMORY ADDRESSES The following information provides two methods of determining which memory range is used to shadow the system and video BIOS on AST computers equipped with the Shadow feature. In addition to copying the system BIOS, AST Shadow BIOS also has the option of copying the video BIOS. However, the video adapter must be an AST VGA adapter or on-board VGA. The memory range used to shadow the BIOS is based on the CPU type and system architecture. The memory locations on earlier Premium systems differ from those currently manufactured. To determine which memory locations are used by Shadow BIOS, it is necessary to identify the system's CPU type either by the part number of the processor board or using the DOS DEBUG program. Listed below are the steps to identify the CPU using DEBUG and which memory locations that system uses for Shadow BIOS. Also included are processor board part numbers as an alternative to running the DEBUG program. DEBUG At the DOS prompt, type: DEBUG and press the key. is a prompt to press the "enter" key. At the DEBUG prompt "-", type lines 1 and 2. Line 1. -OE0 7 Line 2. -IE1 Line 3. -nn Note: The number displayed on the third line identifies the CPU type. If this value is a number between 12 and 18, Shadow BIOS uses the memory locations shown in Method #2. Any other value identifies the use of memory locations shown in Method #1. Enter Line 4 to leave DEBUG. Line 4. -q METHOD #1 When this method is used, the system BIOS uses a 64KB block at F0000-FFFFF. However, when the system BIOS is shadowed, the E0000-EFFFF range is also reserved whether the video BIOS is shadowed or not. If the video BIOS is shadowed it resides in a 32KB block at E0000-E7FFF and the remaining 32KB of that block is reserved.

TECHNICAL BULLETIN #0636 10-02-90 ============================================================================= PREMIUM 486/25 - NOVELL AND IBM TOKEN RING CARDS Problems have been reported with IBM Token Ring Adapter cards (full length, 8 bit) and Premium 486/25 systems with cache enabled when loading Novell's IPX.COM. The Token Ring Adapter card fails initialization when executing the IPX.COM file. The cause of the problem has been isolated to a software timing loop that executes too fast for the Token Ring Adapter board to complete its initialization before the driver times out and produces the error message. The cause of the problem is the IBM Token Ring Adapters inability to initialize fast enough on high performance systems such as the Premium 486/25. The following options are available to customers experiencing the above problem: 1. Disable and enable the cache using AST's SPEED.COM program prior to executing IPX.COM by entering the following commands (in the order they appear) at the DOS prompt: > SPEED CACHE=DISABLE > IPX.COM > NETx > SPEED CACHE=ENABLE 2. An alternate solution is to update the IBM Token Ring card to a short card (IBM part number 25f98XX) or a 16/4 (IBM part number 25f73XX) card. Customer should contact their IBM Dealer for information regarding these cards. ============================================================================= AST RESEARCH, INC.

Parity errors are generated by memory installed on the Rampage board, either at the time of system boot up, or during the running of an application. This incompatibility exists as a result of the method by which the Zenith system performs memory addressing. The Zenith implementation of memory read/write cycles does not allow enough time for data from the Rampage memory to be stable, thus the parity errors. Any hardware change made to the RampagePlus/286 to resolve this incompatibility would prevent the board from operating in AST, IBM or IBM- compatible systems. Therefore, Zenith should be contacted directly for a resolution. ============================================================================= AST RESEARCH, INC.

TECHNICAL BULLETIN #0651 12-03-90 ============================================================================= BRAVO/386SX - SEAGATE 157A Bravo/386SX systems which have the AST part number 500801-XXX may have Seagate ST-157A hard drives installed. The AST part number for this drive is 230119-001. These drives are 40MB IDE type drives, which are configured as drive type "17" in the Bravo's CMOS setup. The following items are important for proper operation of the system but are not documented by AST: 1. These drives are configured to operate as the main hard drive in a system. They are not to be configured, and will not operate as a "slave" to another hard drive which is installed as a "master" in this system. 2. There is a jumper block on the control PCB labeled "J2". It is located at the left rear of the board when viewing the drive from it's front panel. It is comprised of three pairs of 2-pin headers labeled "1" through "6". For use in this system the pair labeled "1" and "2" must have a jumper installed. This configures the drive for a single drive system. Also, the pair labeled "5" and "6" must have a jumper installed. This enables the "external LED", sending the drive activity signal to the front panel of the Bravo/386SX. ============================================================================= AST RESEARCH, INC.

TECHNICAL BULLETIN #0653 12-14-90 ============================================================================= BRAVO/486 CONFIDENCE TEST Corruption of the display occurs during the execution of the Confidence test ASTTEST.EXE. This test is included with the Bravo Utilities (AST part number 910402-XXX). During the portion of the test called "System Board Test", random characters are displayed on the screen, distorting informational text regarding the test. This occurs due to an incompatibility between the system BIOS and version of utilities in use. When version "X1" of the Bravo utilities is used on a system with version 1.01 (or later) of the BIOS (AST part numbers 230807-001 and -002) installed, the above symptoms will appear. Use revision "A" (or later) of the utilities with this BIOS version. ============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0654 12-21-90 ============================================================================= PREMIUM 386/16 WITH MATH CO-PROCESSOR Erratic operation may occur when using a math co-processor in the Premium 386/16. This condition was first observed when running AutoCAD Release 9 and 10. The system may lock up when running software that uses the math co- processor after the system has warmed up (anywhere from immediately to 30 minutes). The failure is encountered consistently after re-booting until the system has been shut off and allowed to cool down. The cause of the problem is a contention with the 87BUSY* signal from the math co-processor. The contention situation is eliminated by lifting or cutting pin 16 on the chip at location U34 on the Premium 386/16 processor board (AST Part Number 202323-001). Denoted after the part number is a revision letter (i.e., 202323-001C). Use the following list to determine the appropriate action to be taken: Revision Action C or earlier You should return the board to AST for modification. D Modification may be performed by an AST Authorized Service Center. E or later Modification has already been implemented, and no action is required. WARNING: This operation is meant to be performed on Premium 386/16 processor boards only (AST Part Number 202323-001), NOT on Premium 386SX/16 or 386SX/20 processor boards. All modifications should be performed by an AST Authorized Service Center. ============================================================================== AST RESEARCH, INC.

TECHNICAL BULLETIN #0665 02-14-91 ============================================================================== GUIDELINES FOR USING NOVELL'S COMPSURF UTILITY The following are some general guidelines that should be followed when using Novell's compsurf utility: NEVER use the format option in COMPSURF when: - Using a SCSI drive. - Using a drive over 1024 cylinders. - Using a WD1007A-XXX hard drive controller. - Hard drive manufacturer forbids it. To successfully prepare a hard drive (over 1024 cylinders) for Novell, do the following: - Set drive type in CMOS per manufacturers recommendations. - Low-level format using the manufacturers format utility (i.e., HDFORMAT for an AST drive). - If the drive requires the Novell compsurf "stamp", run compsurf but DO NOT take the format option. - As soon as the compsurf utility starts, it will check track 0. Immediately after the track 0 test is completed (usually within 45 seconds), hit the ALT + F10 keys twice. This should stop the compsurf utility and "stamp" the drive. ============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0666 02-13-91 ============================================================================= NOVELL COMPSURF WITH ESDI DRIVES Problems may occur when running Novell's Compsurf Utility with AST's OEM version of the WD1007 ESDI controller (AST part number 240018-001) and the Maxtor 4380 320 MB hard drive (AST part number 230055-320). Examples of some errors are as follows: - Abend: Disk Channel 0 could not reset controller - Unable to access Sector 14 - Unable to read bad block table To resolve the above problems, you must do the following: - Do a low-level format using the manufacturer's utility software (i.e., HDFORMAT.EXE for an AST drive). - Run Novell utility ESDIDISK.EXE. (Do not attempt more than three passes.) NOTE: The Novell utility ESDIDISK.EXE is available on Novell's Bulletin Board (NETWIRE) and is listed as ESDIDR.ZIP in Library 6, Forum A.

This includes applications, such as Windows 3.0 and extended memory managers (i.e., QEMM and ASTEMM). This problem is caused by the 386SX microprocessor's requirement for applications or memory managers using extended memory to run in protected mode only. All 386SX "notebook" type computers, equipped with a Suspend/Resume feature, exhibit this anomaly and to date, there are no known resolutions. ============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0682 05-06-91 ============================================================================= AST PREMIUM SYSTEMS WITH BUILT-IN MOUSE PORTS AND ADIC'S DCB When installing two ADIC DCB controller cards, Channel 1 and Channel 2 in an AST computer, errors will occur on the second DCB controller which is Channel 2, (i.e., Channel 2 will fail to initialize under Novell Netware environment and will also fail ADIC diagnostics). The problem lies with IRQ12, which supports the PS/2 mouse port. ADIC's DCB controller card Channel 2 is hard wired, this cannot be changed. (IRQ12 is accepted as Industry Standard for PS/2 mouse port). ADIC's Technical Support recommends that the customer using the DCB Channel 2, switch and use DCB controller Channel 3 which uses IRQ10.

TECHNICAL BULLETIN #0689 04-30-91 ============================================================================= PREMIUM II SYSTEM BIOS AUTOSENSE FEATURE The Premium II BIOS (version 2.0 and above, AST part numbers 237826-001A and 237827-001A) supports a feature known as "Autosense". This feature allows the BIOS to automatically sense, and use, optimized parameters which take advantage of the full capacity of IDE type hard drives. Prior to this feature, the parameters for a particular drive had been determined by entering a discrete value (e.g. "17") in SETUP. This value had to operate with drives from several vendors, so these parameters were not always optimal for a particular drive. This means that the same drive configured by these two methods will have two different sets of parameters, particularly the number of cylinders. Therefore, a drive which has been partitioned and formatted under a discrete drive type may have to be re-partitioned and re-formatted when configured by the autosense feature. Make sure the following steps are taken before using autosense to configure a drive: - Save the data currently on the drive. Save only files and directories, not partition information. - Run SETUP and choose "AUTO" for drive type. A set of parameters will be returned for the installed drive. Save the configuration and exit SETUP. - Re-partition and re-format the drive under the new configuration, and restore the original data. Note: The Conner CP-3000 40MB drive (AST part number 230092-040) cannot be configured via the autosense feature. This drive must be manually configured as type "17" in the SETUP program. ============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0690 06-18-91 ============================================================================= EXCESSIVE HEAT IN TOWER EISA SYSTEMS Tower EISA systems with 80486 processor boards installed exhibit intermittent failures under certain operating environments. Normally under these conditions there are one or more Host Bus Adapters (HBA's) or multiple network interface cards installed in the system as well as the processor card. The failures exhibited are: - Complete system halts, forcing a reset of the system, - Error messages generated by the operating system in use. The cause of these intermittent failures has been proven to be caused by excessive heat buildup in the tower enclosure due to improper placement or installation of the enclosure itself. To insure proper operation of Tower EISA systems in all operating environments, the following guidelines must be met: 1. Proper ventilation must be supplied for the Tower enclosure 2. Ambient air temperature must be within the specifications stated in the Tower User's Manual. 3. All system covers, including drive bay covers, must be installed while the system is operating. These enclosures are designed for optimal air flow with the covers in place. 4. The processor board installed in the system must be a particular revision level. The processor boards listed below have a vented bracket (AST part number 200412-001) installed which aids air flow. Processor Board Part Number Revision 486-25 202361-002 N 486-33 202361-004 D 486-25 202361-005 D 486-25 202361-006 B 486-33 202361-007 B 486-25 202397-001 X3 486-33 202397-002 B ============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0691 06-19-91 ============================================================================= PREMIUM II ILLEGAL CMOS VALUES Premium II systems, while running Power On Self Test (POST), may display the status of cache memory as "Disabled", but CMOS SETUP displays cache as "Enabled". These contrary indications are caused by two bits in CMOS memory being set to illegal values. Systems affected are those with version 2.00 BIOS (part numbers 237826-001 A and 237827-001 A) installed. The illegal setting can be verified by entering SETUP and using the PAGE DOWN key (instead of using the TAB key) to view the status of "Cache Memory". With the illegal values set, this field will show that neither "Enable" or "Disable" has actually been selected. To insure that the cache feature is properly enabled and functioning, perform the following steps: 1. Enter the SETUP program as described in the Premium II User's Manual. 2. TAB down to the "Cache Memory" field and use the ARROW keys to choose "Disable". 3. TAB to the next field down, then SHIFT-TAB immediately back to the "Cache Memory" field and choose "Enable". 4. Save the new configuration upon exiting the SETUP program. The system will boot and display "TESTING CACHE ......ENABLED" during POST, and the cache feature will function normally. ============================================================================= AST RESEARCH, INC.

REASON: Cost effective way to have multiple nodes access emulation while only having one emulation card and additional gateway software. HARDWARE REQUIREMENTS: AST 5251/12 (CC-432 Adapter) Emulation Package. A NETBIOS Compatible Local Area Network already installed and operational. Synchronous Modems (NOT HAYES COMPATIBLE) SOFTWARE REQUIREMENTS: 5251/12 Emulation Version 4.30 (part number 910408-001, 910408-002 and 910408-003). 5250 Gateway Option Version 4.30 (part number 910411-001) NOTE: Versions of both 5251/12 Emulation Software and 5250 Gateway Software may be updated in the future. HARDWARE SET UP: AST 5251/12 Adapter IRQ=2; I/O=300-30F (DEFAULT) The above settings are factory default. If a conflict arises with other hardware in the PC, the user should consult with the conflicting hardware's reference manual for the settings and change the AST hardware and software, or vice versa, in order to resolve the conflict. For installing and connecting the two Synchronous Modems please refer to the Modem Manual, the AST 5251/12 User's Manual (part number 000427-001A) and the AST CC-432 User's Manual (part number 000140-001E) for more information. Note: This document assumes that the user is qualified to establish a successful Modem connection with the IBM Host. INSTALLATION: The Master PC contains the AST CC-432 Synchronous Communications Adapter, the 5251/12 Emulation program, the 5250GATE.EXE program which is attached to the network. The Slave PC contains the KERNELGW.EXE program which is attached to the network. A. MASTER PC CONFIGURATION 1. Type the following at the DOS prompt for the directory that contains the AST 5251/12 Emulation Software: C:\AST> CFG5251 [Enter] This assumes that the subdirectory name is AST and is located on the C: Drive. 2. Answer (n)o for MASTER CLUSTER. 3. Answer (n)o for ASYNC DIAL UP. 4. Answer (y)es for MASTER GATEWAY. 5. Answer (n)o for QUICK START. 6. From the AST 5251/12 Configuration Program (CFG5251.EXE) menu, highlight EDIT and press [Enter]. 7. Answer (y)es to modify the configuration file, AST5251.CFG. 8. The EDIT 5250 CONFIGURATION menu will appear with the following options: HARDWARE KEYBOARD STATION SECURITY VDISK CUSTOMIZE CLUSTER GATEWAY QUIT 9. Highlight HARDWARE and press [Enter]. These options will appear: HARDWARE DSP_ADAPTER QUIT 10. Select HARDWARE again. This is the HARDWARE selection. All the options in this section pertain to how the emulation adapter and communication line is configured. IRQ BPS NRZI I/O_ADR TRACE SDLC QUIT 11. The BPS, NRZI, TRACE and SDLC options are not set from AST (default factory settings). The user must set each option accordingly. 12. The BPS option pertains to the baud rate of the Synchronous Modem that the user is connecting to the AST CC-432 (AST 5251/12) Communications Adapter. Under this option the following list will appear and the user should select the correct rate: 1200 2400 3600 4800 6000 7200 8000 9600 QUIT 13. The NRZI option is host (IBM System 34, 36, 38 or AS/400) controlled. This is IBM's error correction detection system. It is either ON or OFF. The user must verify this parameter with the host's system operator. 14. Under the TRACE option these options will be displayed: NONE SNA SDLC QUIT Note: It is recommended that the TRACE option be used as this is a good trouble shooting tool. With this option selected the user will observe a fixed set of numbers followed by incremental numbers on the bottom left and right hand corners of the display during emulation. The numbers on the left bottom corner indicate that the AST package is receiving data from the Modem and the numbers on the right bottom corner indicate that the AST adapter is transmitting data to the Modem. If there are no numbers at either corner then it indicates that the Modem is not communicating with the AST CC-432 Adapter. Several probable causes for this occurring are as follows: A. Bad or wrong type of cable connecting the Modem to the AST CC-432 Adapter. User could be using a standard asynchronous null Modem RS-232 cable that does not have pin 15 (transmit clock) and pin 17 (receive clock) connected. B. IRQ or I/O_ADR conflict between other hardware in the PC with the AST Adapters. C. Memory resident (TSR) programs such as; fixed disk organizers, menu programs, keyboard macro programs, and etc., that may conflict with the AST 5251/12 Software. D. The NRZI option does not match between the host and AST 5251/12 Emulation. 15. Highlight SDLC and press [Enter]. This is the controller station address configured at the host (IBM System 34, 36, 38 or AS/400) site. The user must verify this parameter with the host's system operator. It is a hexidecimal value and ranges from 01 through FE. Enter the appropriate value and press [Enter]. 16. Press the ESC key and then highlight DSP_ADAPTER and press [Enter]. Highlight DSP_ADAPTER on the next screen and press [Enter]. Next highlight the type of display adapter you are using and press [Enter]. Example: "Color". 17. Press ESC until you return to the EDIT 5250 CONFIGURATION menu. Highlight STATION and press [Enter], the following list will appear: 0 2 3 4 5 6 7 8 9 QUIT 18. Station Address 0 will always be configured as a 5251/12 display type. This cannot be changed. Station Address 1 is reserved for SNA and is not available. The address scheme for the AST 5251/12 Station Addresses and the IBM Host Addresses are as follows: STATION option (AST) 0 2 3 4 5 6 7 8 9 Ports on IBM 0 1 2 3 4 5 6 7 8 Respectively for an IBM 5251/12 (what AST is emulating) remote controller where all device codes are configured for workstation address 0. Page 3-12 of the AST 5251/12 User's Manual (AST part number 000427-001) displays this scheme in more detail. 19. Highlight STATION Address 2 and press [Enter]. These options will appear: DISPLAY PRINTER CLUS_DISPLAY CLUS_PRINTER GATE_DISPLAY GATE_PRINTER QUIT 20. Highlight GATE_DISPLAY and press [Enter]. 21. Highlight 5251/11 (can also select 5291-1 or 5292-1 but will use a 5251/11 for this example) and press [Enter]. Press the ESC key when asked to "enter new session name for station address 2". For this configuration, session names will not be used. 22. Repeat steps 19 through 21 as many times as needed to configure all the station addresses that will be given to the Gateway. In this example a total of seven sessions are configured. Make sure that the number of sessions configured on the AST 5251/12 software matches the number that the IBM host will be allocating to the Gateway. 23. Highlight the other addresses and select the appropriate DEVICE TYPE and press [Enter]. Configure the station addresses as follow: ADDRESS 0 - 5251/12 DISPLAY IBM-API: OFF ADDRESS 2 - 5251-1* GATE DISPLAY (NO SESSION NAME) ADDRESS 3 - 5251-1* GATE DISPLAY (NO SESSION NAME) ADDRESS 4 - 5251-1* GATE DISPLAY (NO SESSION NAME) ADDRESS 5 - 5251-1* GATE DISPLAY (NO SESSION NAME) ADDRESS 6 - 5251-1* GATE DISPLAY (NO SESSION NAME) ADDRESS 7 - 5251-1* GATE DISPLAY (NO SESSION NAME) *The type of display can vary depending on what the host is configured for. The other device types that can be emulated by the AST 5251/12 software or the 5291-1 and the 5292-1. Note: This sample is configured so the Slave PCs will be assigned an address/session on a first-come first-serve basis which is called "session bidding". 24. When all the required addresses are selected press ESC until you reach the AST 5250 CONFIGURATION PROGRAM menu. Now save the MASTER/PASSTHROUGH configuration settings and exit to DOS. 25. Highlight SAVE and press [Enter]. 26. The program will ask "Save configuration file: AST5251.CFG (Y/N)?" Respond "yes" and press [Enter]. This concludes the configuration of the MASTER PC. B. SLAVE PC CONFIGURATION You can use one configuration file for all the network node SLAVES provided that all the Slaves have the same type of display. The slave software when executed will look at the master configuration software to see what gateway displays are available. 1. Type the following at the DOS prompt for the directory that contains the AST 5250 Gateway Software: C:\GATE\CFG5251G [Enter] This assumes that the software is located in a subdirectory named GATE which is on the C: Drive. 2. Answer (n)o for QUICK START 3. From the AST 5250 CONFIGURATION PROGRAM menu, highlight EDIT and press [Enter]. 4. Answer (y)es to modify the configuration file, AST5251G.CFG. 5. The EDIT 5250 CONFIGURATION menu will appear with the following options: HARDWARE KEYBOARD STATION SECURITY VDISK CUSTOMIZE CLUSTER GATEWAY QUIT 6. Highlight HARDWARE and press [Enter]. Highlight DSP_ADAPTER and press [Enter]. Highlight DSP_ADAPTER again and press [Enter]. Select the appropriate display adapter for this particular SLAVE PC (Mono or Color). NOTE: If the Slaves on the network have various types of displays (i.e., monochrome and color), different configuration files (AST5251G.CFG) will need to be created to match each type of display. 7. Press the ESC key until you return to the EDIT 5250 CONFIGURATION menu. Highlight STATION and press [Enter]. 8. STATION ADDRESS 0 is already configured for you. ADDRESS 0 - 5251/11* DISPLAY IBM-API: OFF (NO SESSION NAME) *The device type can also be a 5291-1 or a 5292-1. For this setup you do not need to delete or reconfigure. Address 0 on the MASTER PC is taken by the 5251/12 Controller so this SLAVE PC configuration would then go to the next available session on the MASTER PC which would be address 2. Note: We are setting this up for "session bidding", therefore we do not need to configure the exact station address for the slave. When the slave software is executed, it looks at the master configuration to see which gateway display is available. This is called session bidding. This is how all the slave configurations should be set up for session bidding. 9. Press the ESC key until you return to the AST 5250 CONFIGURATION menu. The user will now save the SLAVE PC configuration settings and exit to DOS. 10. Highlight SAVE and press [Enter]. 11. The program will ask "Save configuration file: AST5251G.CFG (Y/N)?" Respond (y)es and press [Enter]. 12. Highlight QUIT and press [Enter]. 13. Repeat Steps 1 through 12 at each SLAVE PC as needed. This concludes the configuration procedure for the SLAVE PC. C. ENHANCED KEYBOARD CONFIGURATION If you have an Enhanced Keyboard (Function Keys located across the top), you need to run an additional configuration program. Without running emulation, insert the AST5251/12 Terminal Emulation Diskette 2 of 3. 1. Type: A:[Enter] 2. Type: ASTKBD [Enter] 3. Use your down arrow key to highlight the COUNTRY selection. 4. Use your left arrow key to highlight the UNITED STATES as country type. 5. Use your down arrow key to highlight the KEYBOARD selection. 6. Use your left arrow key to highlight the ENHANCED-LIKE for the keyboard type. 7. Use the down arrow key to go to the PROCEED option and press [Enter]. 8. Type the drive letter and subdirectory where the KERNEL.EXE file is located for the MASTER PC or where the KERNELGW.EXE file is located for the SLAVE PC 9. Use your down arrow key to get to the EXIT TO DOS option and press [Enter]. This should be done for each machine that has the enhanced keyboard. D. STEPS FOR PROPER EXECUTION The following steps will show the proper sequence of loading the emulation and gateway programs: 1. MASTER PC A. Load your network programs. B. Load NETBIOS. C. Execute KERNEL.EXE. D. Execute GATE5251.EXE. E. Execute APS.EXE. 2. SLAVE PC A. Load your network programs. B. Load NETBIOS. C. Execute KERNELGW.EXE. D. Execute APS.EXE. ============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0705 09-17-91 ============================================================================= PREMIUM EXEC AND LCD BORDER COLOR Customers have noticed different border colors on the Premium Exec 386SX/20. These colors are blue and black and are only observed by looking at the edges of the Liquid Crystal Display (LCD) on the Premium Exec 386SX/20. AST's Portable Marketing department has concluded that this is not a problem. All three (3) LCD's that AST sources for use in the Premium Exec have a unique border color. The reason for the color difference is only possible to note when looking at the edges of the LCD, since the color beyond the edges is reversed out to white. Most importantly, AST has not compromised the quality of the Premium Exec 386SX/20 in any way by using multiple LCD sources. ============================================================================= AST RESEARCH, INC.

TECHNICAL BULLETIN #0707 10-10-91 ============================================================================= PREMIUM II 486SX/20 AND LOTUS 123 RELEASE 3.1 SYMPTOM: Unable to input numeric values into the Lotus 3.1 worksheet. The numeric values appear only as zeros while alphanumeric values are fine. PROBLEM: Lotus 3.1 recognizes that the system has a 80486 Processor and assumes that there is a Math Coprocessor available. This is true for the 80486DX Intel Chip but not for the 80486SX. When a Math Coprocessor is present, Lotus passes on the tasks of numeric calculations to the Math Coprocessor which is not available in the Premium II 486SX/20 as a standard option. This can be checked by accessing the Worksheet Status Menu option which will show the system information such as; Available memory, Processor type, Math Coprocessor type and other Lotus configuration information. SOLUTION: By typing "123 -s" at the Lotus 3.1 prompt the Premium II 486SX/20 system will be recognized as a 80386 system with no Math Coprocessor, enabling Lotus to handle the numeric calculations. The "-s" switch instructs Lotus that the system has a 386 Processor with no Math Coprocessor instead of a 486 Processor. This will allow the Premium II 486SX/20 to be able to input numeric data. Lotus is also aware of this issue and customers can contact Lotus at (800) 343-5414 and order the Lotus 3.1 update which resolves this problem. With this update the Lotus program will no longer assume that the 80486 Processor has a built-in Math Coprocessor and the "-s" parameter will no longer be necessary. ============================================================================= AST RESEARCH, INC.

Some of the problems experienced are as follows: Shaking of the screen. Slight shift of the screen. A line down the center of the screen. A loss of the screen when switching between video modes. PROBLEM: The current BVHVGA.DLL driver under AST OS/2 version 1.21 instructs the video chip on the AST system board to generate an output of 34.4 kHz instead of the VESA (Video Electronics Standard Association) specified horizontal frequency of 35.2 kHz for SVGA monitors. The AST SVGA monitors follow the VESA specifications for the horizontal frequency. SOLUTION: A driver called BVHVGA.DLL with the byte size of 37994 is available on the AST BBS under the file name of OS2-VGA.ZIP which is located in the file area called SYSTEMS. This driver sets the video chip output to match the VESA specified SVGA horizontal frequency of 35.2 kHz for the AST SVGA monitor. This new driver will be incorporated in AST OS/2 version 1.3. ============================================================================= AST RESEARCH, INC.

TECHNICAL BULLETIN #0744A 03-04-92 ============================================================================= AST 486 BASED SYSTEMS WITH ADAPTEC 1540 AND 1542B PROBLEM: AST 486 based systems using an Adaptec 1540 and 1542B SCSI HBA shows a significant loss of performance by Checkit and Sprinrite. Data transfer rates are reduced by 33 percent when compared to a Premium/386-33 or a Premium 386SX-16 system. CAUSE: Adaptec's controller request for the bus are being held off while the 486 completes code fetch sequences from Adaptec's byte-wide BIOS ROM. This results in 16 accesses to the ROM over the bus, because the 486 processor fetches 128 bits at a time then releases the bus. The 386 processor fetches 32 bits then releases the bus. Since the 486 processor holds Adaptec controller off the bus longer during this access, the overall performance is significantly reduced as compared to the 386 based system. AFFECTED SYSTEMS: AST 486 based systems SOLUTION: It has been determined that this problem will not be fixed. Customers experiencing this problem should use QEMM-386 version 5.1 or equivalent as a workaround. This application will allow shadowing of the Adaptec BIOS which will resolve the problem. ============================================================================= AST RESEARCH, INC.

CAUSE: The ASTART.EXE program supplied with the RampagePlus/MC board does not correctly register memory on the IBM reference disk, which allows the DCA 3270/MC board to corrupt the RampagePlus/MC memory configuration. SOLUTION: Use the ASTART.EXE (version 1.21.01) available on the AST On- Line! BBS. (This is not an AST released driver, and AST makes no warranty regarding the usability of this driver). ============================================================================= AST RESEARCH, INC. TECHNICAL BULLETIN #0748 03-18-92 ============================================================================= BIOS SHADOWING IN AST SYSTEMS This document presents information on the topic of BIOS shadowing. Persistent misinformation and rumors abound on BIOS shadowing. If properly informed most users should view shadowing as a positive and significant performance enhancer rather than a feature to be avoided. Performance: System BIOS and video BIOS shadowing is done to improve performance. This is done by executing the BIOS code out of RAM rather than ROM. A performance gain is achieved by executing out of RAM because it has a much faster response time than the ROM. The slower response time of the ROM acts as a barrier to today's higher speed processors. Shadowing Location: During POST the system BIOS copies an image of itself as well as an image of the video BIOS into RAM. The location where this image is copied depends on the vendor's philosophies as well as hardware capabilities. The AST philosophy is to follow the strategy of "in-place" shadowing. What in-place shadowing means is that the system BIOS will be copied into RAM located at F000:0 and the video BIOS will be copied into RAM located at C000:0. For those familiar with the PC architecture, in-place shadowing locates the shadowed BIOS at the same location as the ROM version (unshadowed BIOS). Early in AST's systems history, the hardware was not able to support the in- place shadowing strategy. The very early systems would shadow the system BIOS at F000:0 but the video BIOS had to be shadowed at E000:0. Progress in AST's hardware development made in-place shadowing possible for systems starting in the latter part of 1989. The choice of shadowing in-place or not is limited by hardware and is not a BIOS design issue. Advantages of In-place: Shadowing in-place has the significant advantage of conserving valuable upper memory addresses. A typical unshadowed system will utilize a total of 96K bytes of valuable address space between the 640K and 1M region. This is allocated as 64K bytes at F000:0 for the system BIOS and 32K bytes at C000:0 for the VGA BIOS. The AST strategy of in-place shadowing utilizes exactly 96K bytes of this valuable address space when shadowing is activated. A different shadowing strategy commonly utilizes 160K bytes of this address space between 640K and 1M. The chart below illustrates how the in-place shadowing strategy conserves valuable upper memory addresses. Upper Memory Address Utilization: No Shadow In-Place Other Scheme C0000-C7FFF VGA BIOS VGA BIOS VGA BIOS (ROM) E0000-EFFFF not used not used VGA BIOS (Shadowed) F0000-FFFFF system BIOS system BIOS system BIOS total space 96K bytes 96K bytes 160K bytes The second significant advantage of in-place shadowing is that it presents the same characteristics as the typical unshadowed system. For programs which "sniff" or search the 640K - 1M region, a system which has in-place shadowing has the video BIOS and system BIOS in exactly the same locations as the typical unshadowed system. There is no anomaly as in other shadowing strategies which have a video BIOS located at C000:0 (the ROM image) as well as at E000:0 (the shadow image). Reserved Memory: All current AST systems as well as all new AST designs have 128K bytes of reserved memory set aside to support shadowing. All memory except this 128K bytes is available to the user. The reserved memory is used as the shadow RAM. There has been no attempt to design systems where only 96K is reserved rather than 128K. Providing this extra 32K to the user would significantly increase hardware costs. There are a few exceptions to the 128K reserved memory rule. The Bravo 286/16 is an example of a system which gives reserved memory back to the user. This extra 128K is available if shadowing is turned off in specific memory configurations. Because of the costs and complications involved to provide an extra 128K bytes of memory for the minority of users who wish to disable shadowing, AST systems will continue with the 128K reserved memory rule. Write Protection: Write protecting the shadowed BIOS is important as it prevents program bugs or poorly designed programs from destroying the video or system BIOS images in RAM. This issue affects AST as well as all system vendors. This write protection attribute coupled with the in-place shadowing yields the perfect shadowing scheme. Systems with cache can present a wrinkle in write protecting the shadow RAM. Until very recently, AST systems with cache did not provide the hardware capability to write protect the video BIOS shadow area. Write protection of the video BIOS shadow area was complicated by the fact that the cache was caching the video BIOS addresses. (The system BIOS area has been write protected as the cache does not cover the system BIOS addresses.) With the exception of 486 based systems, recent AST designs now fully write protect the shadowed BIOS areas. The internal cache of the 486 chip presents a challenge to write protection schemes which AST as well as all other vendors are faced with. Essentially there are no hooks in the 486 which allow hardware designers to implement write protection of shadowed areas which are covered by the 486's cache. While full write protection could be achieved by preventing the 486 cache from covering the video BIOS area, this results in a significant performance degradation in video benchmarks. The AST solution to the write protection dilemma of 486 systems is to write protect the shadow RAM. While this does not prevent the cached copy of the video BIOS from being overwritten, the cache will always be able to fetch a correct copy from the protected shadow RAM whenever a cache load cycle is done. This pseudo write protection of the video BIOS presents a much smaller window of vulnerability to program bugs. Permanent Shadowing: All new AST systems and recent BIOS updates provide a feature called permanent shadowing. This feature no longer provides the user with the option to disable shadowing. With in-place shadowing and write protection of the shadowed BIOS, there is little reason to disable shadowing. Disabling shadowing only provides the user with a slower system. As mentioned earlier the reserved memory is typically not returned back to the user when shadowing is disabled. Summary: This paper has attempted to answer many of the persistent questions surrounding shadowing. It has also reiterated the long term AST strategy which, when implemented, results in the perfect shadowing scheme. ============================================================================= AST RESEARCH, INC.

TECHNICAL BULLETIN #0750 04-01-92 ============================================================================= PREMIUM EXEC NI-CAD BATTERY INFORMATION PROBLEM: All Nickel-Cadmium (Ni-Cad) rechargeable batteries have the inherent "memory" property that can cause early low voltage indications and premature system shutdown. CAUSE: When a Ni-Cad battery is put through repeated partial- discharge / recharge cycles, and is drained to approximately the same level each time - down to half capacity, for example - it develops a "memory" of this point in the discharge process. Once established, Ni-Cad memory distorts the battery's voltage output profile. The battery will produce a normal voltage until drained to the memorized location, but thereafter its voltage output abruptly sags to a sub-normal value, and stays below normal until actual battery depletion. The voltage depression can be deep enough to cause the Notebook to prematurely issue the low battery warning (audible beep and lighted amber LED) or battery fail warning (audible beep and blinking amber LED.) SOLUTION: The Ni-Cad battery "memory" effect can be corrected by "conditioning" the battery, a process which simply consists of fully discharging the battery before recharging. The battery pack should never be disturbed while the system is in use or while the battery is being charged. To remove or install a battery, the system should be powered down and the AC adapter removed. AST recommends conditioning the battery pack monthly to promote optimum performance. Conditioning of new, out-of-the- box Ni-Cad battery pack is also strongly recommended. Listed below are the steps required to correctly condition the Premium Exec Ni-Cad battery: 1. Charge the Ni-Cad battery up to full capacity. 2. Disconnect the AC adapter. 3. Configure the Notebook's Setup Menu as shown below. IMPORTANT: Note that Suspend must be ENABLED! Default Speed: HIGH Backlight Timeout: 0 Hard Disk Timeout: 0 Suspend: ENABLE Software Timeout: 0 (Exec SX-25 and SX-25 color only) Turbo Mode: ON AT BOOT Speaker: ENABLE Other Parameters: Don't care This configuration results in a near-maximum load on the battery during the first part of the conditioning process. Suspend mode then prevents an excessive drain rate as the battery nears depletion. 4. Store the setup menu setting and exit. The system will reboot and the screen will display the DOS prompt. 5. Keep the Notebook powered up with its LCD display open for 12 TO 24 HOURS. Most will find that overnight conditioning of the battery is the most convenient method. It is safe to use the Notebook in the normal fashion during the conditioning process. However, the following precautions must be observed: a. Save your work and exit all applications back to the DOS prompt immediately after the first low battery warning. Allow the Notebook to remain powered up with the LCD display open, however. b. A full 12 hours of on-time will insure complete battery discharge even with premature suspend activation caused by the "memory" effect. 6. After 12 hours, turn the Notebook off. Recharge the battery by attaching the AC adapter. Connect the AC adapter to the Notebook before plugging the adapter into the AC socket. Connecting the AC adapter in this sequence insures that the Notebook battery management system senses all signals on the DIN connector appropriately. NOTE: After completing a "fast discharge", wait at least 5 minutes before connecting the AC Adapter/Charger to recharge the battery. If this is not done, the AC Adapter/Charger could switch to Trickle Charge mode instead of Fast Charge mode. ============================================================================= AST RESEARCH, INC.
