AMI BIOS Recovery

  1. Download the latest version of your BIOS from your computer or motherboard manufacturer’s support site.
  2. Rename the downloaded file to AMIBOOT.ROM. (NOTE: Please see paragraph 3 to make sure you pick the right name)
  3. Copy the file to a floppy disk (or USB)
  4. Insert the floppy disk to the floppy drive.
  5. Turn on the system.
  6. The system should automatically access the floppy drive (indicated LED will light up). If no floppy access occurs press Home to force update. Follow any on screen instruction to restore and recover the good BIOS from the floppy disk.
  7. When 4 beeps are heard or a reboot prompt you may remove the floppy disk.
  8. Restart the computer.

Note: If USB keyboard doesn’t work, try usins 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 doesnt have to be bootable and no flash utility needs to be used. 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.

    I try the same step with my Biostar TA790GXE v6.1 mainboard with no sucess. I use an USB Flash (256MB) instead of FDD. Flash Recovery read the USB but it say “FLASH ROM not detected”

    Any one can help. Many THX.

    • wuhoatu:

      I already try with USB FDD with no sucess.

    • admin:

      The USB Flash device normally needs to be in the primary USB slot on your motherboard in order for detection to be successful with the name “AMIBOOT.ROM” For more support, please consult our forums.

    Many THX for your help but I already tried with old traditional FDD with no sucess. Same above link screen. Also tried with all USB port, none working.

      What kind of USB flash you use?, I was working as engineer in a computer related enterprise, and I remember not all USB drives were usefull to flash BIOS, just old ones (less than 2 GB).

  • Guys,after trying to update my laptop`s bios it shut down and doesnt want to start.No led,no fan,just dead…Any chance to fix this home?!?Or should I go to a service to re-write my bios ?

    • Please identify your BIOS type and try the procedure for your BIOS type. If it doesn’t work we’d recommend you take it into a nearby shop to have it serviced. (Either solder new chip on or order new motherboard).

    Hi. This is my first post and last resort. I can’t get past a blue screen (BSOD)when Windows tries to start which states …The BIOS in this system is not fully ACPI compliant… I’ve researched this site and the web and can’t find an answer that works. I’d like to try to update the BIOS since it’s the original and I think it’s corrupted. There are 2 newer versions but they appear to require windows to run and I can’t boot into windows. My system is:

    HP Pavilion Elite Desktop m9340f
    Q6700 @ 2.66 GHz
    6 GB RAM (2x2GB+2x1GB)
    Asus IPIBL-LB “Benicia” Motherboard
    AMI (HP) BIOS 5.25 dated 6/16/2008
    Core: 08.00.14
    Win Vista 64-bit

    I can get into setup and I’ve cleared the CMOS etc. I’ve booted from a DOS USB stick successfully but when I run AFUDOS with a 5.43 ROM downloaded from here:
    and extracted using 7zip, I get “-Error: BIOS is write protected”
    Any advice/help would be greatly appreciated!
