It is free software and i preffer the sintaxis over gnu as. Nasm is not full intel sintaxis though. Some VESA functions need to run in protected mode. We can write asm code that run in real and protected mode with care about segments. I have see code like that before. I have not see a 486 with pci but maybe it exist.
Most of the BIOS runs in real mode, but I think some of the VESA stuff might be protected mode.

Start with minimal, then add incrementally. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
