INT 2F - Novell NetWare - Adv NetWare 4.0 DOS Requester - GET VLM CALL ADDRESS
AX = 7A20h
BX = 0000h
Return: AX = 0000h on success (installed)
ES:BX -> far call address for DOS Requester (see #02859)
Notes: the DOS Requester replaces the NetWare Shell (ANETx, NETx) on
NetWare LAN's as of the release of Advanced NetWare 4.0 (1993). It
is backward compatible with NetWare 2.1x through 3.11 servers as
well. Note that there was a NetWare 4.0 in the early 1980's, which
can cause confusion.
this call is used as the installation check by VLM.EXE, which is the
loader for all the modules of the DOS Requester
.VLMs are standard old .EXE format executables whose normal entry point
merely terminates to prevent loading from the command line (Novell's
VLMs all return errorlevel 6). The real entry point is found by
looking at the VLM header at the beginning of the load image
(see #02862)
Index: installation check;NetWare 4.0 DOS Requester

WORD destination VLM ID (see #02861)

Return: AX = status code (0000h,8811h,8846h,8848h,8853h) (see #02860)
ZF set if successful, clear on error
other registers as appropriate for function

INT 2F - CS_TSR specification - GET PROCESS BLOCK BY PROCESS HANDLE
AX = 8002h
BX = process handle for TSR (see AX=8001h"CS_TSR")
Return: ES:DI -> process block for specified TSR (see #02928)
unchanged if no match for process handle
Note: This function is used to allocate a process handle when the TSR
installs itself, by setting ES:DI to point at something other than
a CS_TSR process block's signature string and iterating through the
possible process handles (0001h to FFFFh) until ES:DI is returned
unchanged

The function is probably implemented in the ARABIC.COM/HEBREW.COM
driver.
The CX = 0 on call is not actually a requirement, but it should be
initialized this way to receive a fontpage 0 if ARABIC.COM/
HEBREW.COM is not loaded. A fontpage 0 indicated no fontpage
support. At least this is what CODEPAGE.COM assumes (by using
the CX=0 init status of a .COM program, when not being loaded
in DEBUG.)

of code page 437

Notes: this call requests execution of the command which a previous call to

BUG: Novell DOS 7.0's COMMAND.COM (prior to Update 12) will attempt to run
a disk program with the indicated name even if the returned length
byte is zero, because the register used to flag this case is
clobbered without first checking it. The workaround is to set the
command name buffer to "REM" followed by enough blanks to pad out
the original command's length, which will also work with MS-DOS 6.

is written over top of the filename passed to the INT 21h call. The
application must provide a sufficiently large buffer. This state is
reset after the next INT 21h call processed by APPEND.
APPEND uses the byte at offset 3Dh in the PSP

Notes: this call replaces the address to which the network software chains on

or transmit
this command should not be used by applications to
set the buffer sizes
06h 6 BYTEs padding (0)
---command 01h---

if the RxCB is opened for RPC, the port number indicates the
allowable RPC (see #03040)

because all TxCBs for a given destination are stored
on a separate subchain, it is necessary to kill all
failed TxCBs to a given destination before any new

Program: NWCACHE is the disk cache included with Personal NetWare,
Novell DOS 7, Caldera OpenDOS 7.01, DR-OpenDOS 7.02, DR-DOS 7.02,
and Caldera Thin Clients/Lineo DR-DOS 7.03.
Note: This function is called by the NetWare Lite and Personal NetWare
SERVER. It may also be called by future (post DR-DOS 7.03)
COMMAND.COM before it returns to the prompt.
BUG: Some pre-BETA 17 (1993/09/28) versions of NWCACHE returned -1,0,1
instead of 1,2,3 for the memory type in CL.

Format of NWCACHE cache statistics:
Offset Size Description (Table 04122)
00h WORD version
02h BYTE memory type
03h WORD initial cache size in KB
05h WORD current cache size in KB
07h DWORD number of read requests
0Bh DWORD number of physical reads performed
0Fh DWORD number of write requests
13h DWORD number of physical writes performed
17h BYTE delay ticks for deferred write (0 if no deferral)
18h WORD maximum number of sectors in lookahead buffer
1Ah WORD number of disk errors
1Ch WORD number of cache memory errors
