Subject:	Info re an interrupt wanted
Message-ID:	<192EC21F07@fs2.mt.umist.ac.uk>

In a Gnu C++ program, I am trying to use the interrupt "AX=0x4f, CX=SuperVGA
video mode, int10" to get SuperVGA mode information in ES:DI etseq for each
possible screen mode for whatever PC the program is running on. Sometimes it
works; usually it divide-overflows somewhere inside the interrupt routine and
exits to DOS with a pig's ear made out of the stack pointers so the computer
locks up soon after. I can find no other easy way that the program can find
this information. As this interrupt seems to have a bug in, please can someone
out there email me a decompilation of the innards of this interrupt routine?,
so I can write my own version with the bug removed.
