i've put the 256mb bios on instead of the 128mb bios and as you would suspect the card will not boot now is there anyway of reverting it back to the original bios (yes, i did back it up ) without using a PCI card? was using nvflash
There used to be an old program called vgabois (not the linux one) that would allow you to test graphics cards bios but I doubt if it is still floating around it save me from making an gf2mx a £125 paperwieght when they first came out.
Depends if the PC boots or not. If it boots, just gives no display, then you can blindly boot to DOS and type in the right commands (or make a batch file to do them from Windows on another computer). If it won't boot at all, then I don't think you have any choice but to find a PCI card.
