The hard part would be actually getting the data out of the BIOS ROM and getting the new data back into it. With an older video card that has a socketed DIL chip for its ROM, it's not too bad, as you could take the chip out, stick it in a programmer, read the data, then stick the equivalent EPROM into the programmer and blow the new data. With a newer card... if its BIOS is in an electrically-erasable non-volatile memory, a Flash or similar, you might be able to find a utility somewhere that would re-flash it, or you might be able to hook an in-circuit programmer up to the relevant lines on the card. In summary, it's probably possible, but you'd probably need to buy or borrow some extra hardware (and boot an M$ OS to drive it)... exact details would vary from card to card. -- Pigeon Be kind to pigeons Get my GPG key here: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x21C61F7F
