Yes. With clear documantation from nvidia directly for specified chip it would be much easier. I'm not angry they don't provide code for something but documentation is needed to code it myself...

Do you (anybody else here) have any experiences with modern ATI VESA BIOS? I was nvidia fan and had only nv cards for long years. But as I know ATI would be better because it allows you to hardwire your own refresh rates via bios editor even it had only VBE 2.0 so this is an advantage over nv.

> maybe slightly better ... but VESA is 15 years old and has very low

I think VE 3.0 was "only" ~10 years old :) But I'm afraid that VESA nad also VGA compatability will disappear and will be replaced by some EFI. Then it will be end of DOS era on real HW, only emu will be possible.

Another thing how nvidiots sucks my blood (i wrote here to upper thread):
I found another source of problems with running VGA/VESA DOS programs fullscreeen under NT/2K/XP NTVDM - New nVidia BIOSes are missing some functions (VBE-PM?) which cause that any VGA/VESA program I run displays only black screen ad hangs. It happened on 7600GS after VGA BIOS update. The new version is about 5kB smaller so it's clear that something is missing. Solution is downgrade back or use http://www.volny.cz/martin.sulak/videoprt.zip hook driver which gives back some missing functionality. After I installed it I can run VGA/VESA DOS progams as before under XP.

DOS gives me freedom to unlimited HW access.
