Upgrade BIOS on Acer Aspire One

In a previous post I wrote about how easy it was to upgrade the BIOS on Asus Eee Box. It turns out that the Acer Aspire One is just as simple.

  • Go to Acer’s support pages and download the BIOS you want to use.
  • Format a USB stick with FAT32
  • Put the BIOS image file and FLASHIT.EXE (also from Acer) in the root directory. Rename the BIOS image file to ZG5IA32.FD
  • Turn off the computer, then turn it back on while pressing Fn+ESC. Release Fn+ESC after a few seconds. The power button should now be blinking. Press the power button once. This will start the BIOS flashing process.

N.B. Keep the computer connected to AC and do not interrupt the process once it has started. Also, while the above worked very well for me I can offer no guarantees.
