Overview
PROVIEW is a menu driven program used to analyze, view
and edit the basic components of a system, including the
system memory, system interrupts, device drivers, and
installed disk drive sectors and file contents. PROVIEW
will allow you to view system elements in HEX, ASCII or
disassembled code format. Full searching and editing
functions are included.
PROVIEW displays data in real time. For example, if you are
viewing a memory location that is being updated by
the system (the clock interrupt, for example), PROVIEW
will display the changes as they occur.
PROVIEW provides an extensive on-line context sensitive
help function. At any point in the program you may press
the <F1> key to display help text for the process you are
currently engaged in. NOTE: The PV.HLP file must be
in the same directory as the PV.EXE file.
PROVIEW is Novell Network aware. You may view any network
file and edit any network file that is not locked.
Using The Menus
After you have entered the PROVIEW menu system (type
PV at the DOS prompt), you will be able to move
about the PROVIEW menus to access all of the system
functions. To pull down one of the available menus,
press the ALT key and the highlighted letter of the
menu you want or use the mouse to select the pulldown
list. For example, to access the Memory menu, press
ALT-M. To access the functions within the pulldown
list, you can either use the arrow keys to move the
highlight to the option you want and press ENTER,
select the option with the mouse, or press the letter
that is highlighted in that option. For example, in the
Memory menu to access the list of interrupt vectors,
press I.
The PROVIEW menu system allows you to open more than
one window at a time to view the system parameters.
Using the PROVIEW Windows
The Window menu contains commands to close, move and
perform other window-management commands. Most of the
windows in this program have all the standard window
elements, including scroll bars, a close box, and zoom
icons.
Size/Move (Ctrl-F5)
When you choose Size/Move, the active window moves
in response to the arrow keys. Once you've moved
the window to where you want it, press Enter.
If you press Shift while you use the arrow keys,
you can change the size of the active window. Once
you've adjusted its size or position, press Enter.
You can also move a window by dragging its title
bar with the mouse. If a window has a Resize
corner, you can drag that corner with the mouse to
resize the window.
Zoom (F5)
Choose Zoom to resize the active window to the
maximum size. If the window is already zoomed, you
can choose this command to restore it to its
previous size.
You can also double-click anywhere on the window's
title bar (except where an icon appears) to zoom
or unzoom the window.
Next (Ctrl-F6)
Choose Next to cycle forwards through the windows
on the desktop.
Close (Ctrl-F4)
Choose Close to close the active window.
You can also click the Close box in the upper
right corner to close a window.
Cascade
Choose Cascade to stack all file viewers on the
desktop.

Using the Edit Functions
The Edit menu contains all the commands you need to
edit or change the system elements that are accessed with
the Memory and Disk menus.
Undo (Backspace)
To undo any change that you have made. Note that
any values that have been changed are highlighted.
Set Mask/Value (F3)
The mask/value may be set to any hex byte value for
XOR/Negate or Add/Subtract operations.
XOR/Negate (F7/Shift-F7)
XOR/Negate the selected byte using the mask value.
Add/Subtract (F8/Shift-F8)
Add/subtract the Mask/Value to the highlighted field.
Rotate Left/Right (F9/Shift-F9)
Rotate selected byte left or right.
The FILE Menu
The file menu has three options:
Save Edited Object
Permits saving any changes you have made without
having to exit the current edit in process.
Read only (Default = No)
This options allows you to enable or disable the
Read Only function. When enabled (ON), you will
not be able to change or edit any system data with
the PROVIEW program. To make changes, and be able
to save them, toggle this option to read NO.
Exit to DOS
Returns you to the DOS prompt. Be sure to save any
changes that you have made before exiting.
The MEMORY Menu
System memory may be viewed and edited by PROVIEW.
Memory may be viewed in HEX, ASCII or disassembled
code format. If viewing in assembler format, you
may follow the control of the program by selecting
the numbers in parenthesis to the right of each
branch instruction that is displayed on the screen.
to reverse the flow of control, press (0) to return
to the previous branch instruction.
The following options are available in the Memory Menu:
DOS System Area
View/Edit the DOS System Area, starting at 0K and
continuing as much as space as necessary for all
the information loaded. Information stored here
includes the BIOS DATA Area, DOS Communication
Area, IO and DOS code, System File Tables, FCB
Tables, Disk Buffers, System STACKS (CODE and
DATA), as well as devices loaded with the
CONFIG.SYS file (e.g., HIMEM.SYS, SETVER driver,
MOUSE driver).
Program Area
View/Edit the Program Area of memory, starting
at the end of the DOS System Area and including
all used and unused space up to 640K. Information
stored here includes the COMMAND.COM code, as well
as any TSR programs loaded by the system (e.g., MOUSE,
DOSKEY).
Upper Memory Area
View/Edit the Upper Memory Area, starting at 640K
and including all the used and unused space up
to 1MB. Information stored here includes the
Graphic and Text Video RAM, Video ROM BIOS, and
System ROM BIOS.
Interrupts
View/Edit the System Interrupt Vectors. Proview
indicates which ones are currently in use, their
memory addresses, owners and interrupt chains.
You may display/edit the actual interrupt code in
hex or ASM format.
NOTE: Do not use the "Display Interrupt Chain"
sub-function of this feature if you are running
any background multi-programming operating environment
such as DESQview. Your system may hang under some
circumstances if it is attempted.
Drivers
View/Edit installed system device Drivers. PROVIEW
displays the list of installed drivers and their
attributes. Individual drivers may be selected for
viewing or editing.
Absolute Memory View
View/Edit a user selectable memory address range
within the system absolute memory.
WARNING!!
Changes made to system memory can cause system crashes
or data loss. Make sure that you understand any change
that you wish to make to any memory location.
DISK Menu
File View
View/Edit files on the default hard disk drive.
You can view the file in either HEX, ASM or ASCII
format. Files may be selected from hard disk, floppy
diskette or network drives.
Sector View
View/Edit logical sectors on any installed disk
drive, hard or floppy. This option may not be used
on network drives.
Physical Sector View
View/Edit physical sectors on any disk drive. This
option may not be used on network drives.
Boot Record
View/Edit the boot record on any installed drive. This
option may not be used on network drives.
Master Boot Record

WARNING!!
Changes made to the Boot sector, Master Boot Record or
File allocation table area of the hard disk or floppy disk
can cause system crashes and/or loss of data. Make sure
that you understand any changes made to these areas.
HELP Function
Comprehensive context sensitive help is provided with
PROVIEW. At any point in the program press <F1> to
display help instructions for the function you are
engaged in.
In the Help Menu is also a section on Help On Help.

Mouse to return to the PROVIEW menu.
AUTHENTICITY
Before using PROVIEW for the first time, verify that it has
not been tampered with or infected by a virus by using the
the enclosed VALIDATE program. For instructions on using
VALIDATE, please read the VALIDATE.DOC file.
The validation results for Version 1.2 should be:
FILE NAME: PV.EXE
SIZE: 87,885
DATE: 03-05-1993
FILE AUTHENTICATION
Check Method 1: 4C16
Check Method 2: 0048
If your copy of PROVIEW differs, it may have been damaged.
Always obtain your copy of PROVIEW from a known source. The latest
version of PROVIEW and validation data for PV.EXE can be
obtained from McAfee Associates' bulletin board system at
(408) 988-4004 or from the McAfee Virus Help Forum on
CompuServe (GO MCAFEE), or the mcafee.COM anonymous ftp site on
the Internet.
PROVIEW series are archived with PKWare's PKZIP Authentic File
Verification. If you do not see an "-AV" after every file is
unzipped and receive the "Authentic Files Verified! # NWN405
Zip Source: McAFEE ASSOCIATES" message when you unzip the files
then do not use them. If your version of PKUNZIP does not have
verification ability, then this message may not be displayed.
Please contact us if you believe tampering has occurred to the
.ZIP file.
