- Download the latest version of your BIOS from your computer or motherboard manufacturer’s support site.
- Rename the downloaded file to AMIBOOT.ROM. (NOTE: Please see paragraph 3 to make sure you pick the right name)
- Copy the file to a floppy disk (or USB flashdrive).
- Insert the floppy disk into the floppy drive.
- Turn on the system.
- The system should automatically access the floppy drive (indicator LED will light up). If no floppy access occurs, press Home to force update. Follow any on-screen instructions to restore the good BIOS from the floppy disk.
- When the computer beeps four (4) times or a reboot prompt is displayed, you may remove the floppy disk.
- Restart the computer.
Note: If a USB keyboard does not work, try using a PS/2 keyboard. Sometimes, taking out the CMOS battery to clear the configuration settings or resetting the CMOS jumper switch to clear the CMOS may help too. Only the BIOS file is needed. For AMI BIOS recovery, the floppy disk does not have to be bootable and no flash utility is required. This procedure is also applicable with USB drives on most newer systems that use AMI.
IMPORTANT: If you have an HP BIOS and the recovery method above was unsuccessful, please rename the recovery BIOS to HPBIOS.ROM and try again.
