             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: wine-bugs at winehq.org
        ReportedBy: joey_z at anticbbs.strangled.net
    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.
