got still one old TR1 CDROM and Voodoo 2 Cards. Some months ago I managed to play TR1 with the Voodoo 2 Glide patch. I ran this on a ABIT KT7A Board + Athlon-M.
But now for some unknown reason none of the DOS based 3DFX games are working anymore. Everytime the game is changing in to 3DFX hardware rendering the screen went blanc. For instance Descent 2, the DOS space shooter also. Apart from that all other Windows based 3DFX games are still running well as before, so here nothing has changed.
Its just the DOS Problem. I checked the memory, put the Voodoo 2 in severeral slots, removed all other cards, tried some other glide2x.ovl. No success.
I tried the voodoo 2 then on a older ABIT BH6 mainboard with a PIII 500. There everything is working fine. But I want to keep my ABIT KT7A for my Voodoos.
What can cause such a oddly behavior of the hardware. Why don't like my voodoo 2 work in DOS Mode on the ABIT KT7A no more? I assume that there is no physical damage. May it be a BIOS related matter....? hmmmmmmmmm...
Please help....thank you!
/EDIT: I reseted my mainboard BIOS. Now it works again. I will test how far i can go up with CPU Speed an other things...
EDIT: Fixed problem with resetting mainboard BIOS CPU Speed to minimum. Maby faulty CPU.
