Options for recovering from a failed BIOS update:
- Use the backup created by the flash util to restore the previous version
- Have an emergency floppy disk on hand that includes the "boot block" section of your BIOS. This has sufficient support to boot your PC from the floppy. No video is displayed. Once the PC has booted from the floppy and copied the correct BIOS over the corrupts one, reboot your PC.
- Flash Recovery Jumper Switch: Some mfgs include one of these on the mobo. You set the switch to the recovery position, insert the system upgrd into the drive and reboot. The system will boot from the disk and copy original BIOS over the corrupted one. Reset the jumper switch back to normal and reboot again.
- If none of the above work, will might need to replace the BIOS chip with a new one from your mfg.
