The BIOS is a very critical component for correct functioning of your VGA card. We do not recommend users to flash the BIOS themselves because slight difference in  functionality may require a different BIOS completely. Consequently, not all our graphic produts are equipped with flash ROM. If there is no flash ROM on your VGA card and you try to flash the BIOS, the flashing utility may sometimes report the message "EEPROM not compatible". Please note that if you flash the BIOS incorrectly at your own risk, your VGA card may function abnormally and we cannot be responsible for any damages caused.
