Video BIOS for an NVIDIA GeForce 9400 GT graphics card with 1024 MB of memory, dated or versioned 081029 in the name, and marked OK, meaning tested. It comes as an 85.9 KB RAR. A VBIOS is flashed to the card EEPROM with tools such as nvflash or a hardware programmer when the card shows no display or corrupt firmware. Back up the original ROM first and confirm memory size and type match, since a VBIOS for different memory chips can leave the card unstable.
