AA>        Hi, I'm starting to program graphics in assembly

AA>(BIOS calls, screen calls) when doing it in OS/2 or is ASM
AA>exactly the same as in DOS.

There are two API's (Application Program Interfaces) in OS/2 for
graphics, for PM graphics, there is GpiXxxxx and for full screen
graphics there is VioXxxxx.  Generally you use these to do graphics.
There isn't really a BIOS you can use, although you can still do direct
access to video hardware ports - again this is recommended only for the
very advanced.

If you are just learning assembler, I would recommend sticking with DOS
for graphics for now - it will let you do some pretty amazing stuff.  If
you want to use C, then go play with OS/2's graphics.  You might also
check into the DIVE spec for OS/2 - it is interesting.

Rob.
