[Bug 31923] New: when starting an win16 application, "int 2F unknown/unimplemented parameters"

Bug #: 31923
           Summary: when starting an win16 application, "int 2F
                    unknown/unimplemented parameters"
           Product: Wine
           Version: unspecified
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

I have an older win16 program (made for windows 3.x, I wouldn't dare file a bug
report for 2.x or 1.x :) that seems to call a function that is unimplemented or
otherwise undocumented in int 2F AX=7b00. the full error message wine gives is:

err:int:DOSVM_Int2fHandler int2f: unknown/not implemented parameters:
int2f: AX 7b00, BX 0000, CX 001c, DX 1c37, SI 7110, DI ffc0, DS 2157, ES 1c37

after this, the program gives a dialog box that says 'Invalid property value'.
if it helps at all, the program is called 'Worldgroup Manager' and it works on
server 2003 (and it is supposed to work on XP) after enabling a compatibility
fix called 'WOWCFEX_FORCEINCDPMI' (I can supply a more detailed description if
it is needed). I checked the application on windows server 2003 without that
compatibility fix, but it does not give the same error. instead it gives NTVDM
hard errors and then an 'unrecoverable error' not the same problem it seems...
if a copy of the application is needed, it can be supplied. the program is not
the kind of program that you pay for since it is meant to be distributed to
clients of a BBS.

guess I forgot some info I meant to paste in:
wine version: wind-1.3.28
ubuntu version: 11.10
installed wine from a package, not sure which one
used wine "C:\WGMAN\GCSVCMAN.EXE" to start

I'm not seeing INT 2F AX=7b00 nor AH=7b documented on
http://www.ctyme.com/intr/int-2f.htm

Unsure if the WOWCFEX_FORCEINCDPMI compatibility flag plays a role here yet or
if it dies before hitting that.

If you could run your program with WINEDEBUG=+int,+int21,+int31,dosmem and
attach the output that might provide some additional clues.

Wine gives the same output as before when I run it with those options. still
says:

err:int:DOSVM_Int2fHandler int2f: unknown/not implemented parameters:
int2f: AX 7b00, BX 0000, CX 001c, DX 1c37, SI 70fc, DI ffc0, DS 2157, ES 1c37

the application still behaves the same way as well,

As far as the 'WOWCFEX_FORCEINCDPMI' flag goes, if I run it on windows 2003
without this flag, the application doesn't give an error, only NTVDM does
("NTVDM encountered a hard error" or some similar error) so I think it is
probably not producing the problem I am seeing, but it is not impossible.

according to the 'Microsoft Application Compatibility Toolkit', the
WOWCFEX_FORCEINCDPMI flag says this: "Compatibility flag for 16 bit
applications. This forces DPMI memory allocations to use ever increasing linear
addresses. This may prevent the ntvdm from hitting a GPF."

Please change your path in the console window to (wineprefix)/drive_c/WGMAN
and run the command (all in one line):

WINEDEBUG=+int,+int21,+int31,+dosmem,+pid,+tid,+process,+loaddll wine
GCSVCMAN.EXE 2>&1 | tee log.txt

Now attach the file log.txt to this bug.

Is this still an issue in current (1.7.35 or newer) wine? If so, please attach
terminal output.

No download. No name of the application. No answer from the OP since 7 years.
Can an administrator close this bug as ABANDONED?

Marking abandoned.
int 2F AX=7b00 aka AH=7b is totally undocumented. So without the application
there is no chance to figure out anything.
