A loss of power or other similar event during a BIOS upgrade can leave the BIOS in an unusable state. To recover the BIOS, follow these steps:
Be sure a power supply and speaker have been attached to the motherboard.
Be sure a floppy drive is connected as Drive A:
Change the Flash Recovery jumper to the recovery mode position.
Install the bootable upgrade diskette into Drive A:
Reboot the system.
Because of the small amount of code available in the non-erasable boot block area, no video is available to direct the procedure. Consequently, you must monitor the procedure by listening to the speaker and looking at the LED on the floppy disk drive. When the system beeps and the LED is lit, the system is copying the recovery code into the FLASH device. As soon as the LED goes off, the recovery is complete.
Turn the system off.
Change the Flash Recovery jumper back to the default position.
Remove the upgrade floppy in Drive A:
Turn the system on.
NOTE: If the error message “CMOS/GPNV Checksum Bad. Press the F1 key to Run SETUP“ appears during the boot operation, press the F1 key to enter the BIOS Setup Utility. After entering the utility, press the F9 key to load the setup defaults. Finally, press the F10 key to save and exit.
