Acer Aspire One BIOS Recovery

The BIOS is now also available from Acer european server. There is actually a text file included which recommends to flash the BIOS from DOS via a bootable USB stick.

Also available from here if above does not work

BIOS 3310 • Download

First format an USB stick with FAT.

Download the latest BIOS, and put both FLASHIT.EXE and the BIOS file in the root directory of the stick. Rename the BIOS file to ZG5IA32.FD, that's important. Do not remove the USB stick.

Turn off the Acer Aspire One, make sure both battery and AC adapter are connected. 

Press Fn+Esc, keep it pressed and press the power button to turn on. 

Release Fn+Esc after a few seconds, the power button will be blinking. 

Press the power button once. 

The Acer Aspire One will now initiate the BIOS flash, do not interrupt it under any circumstances. After a while the power button will stop blinking, and the Acer Aspire One will reboot shortly after. Wait patiently.

The BIOS has been flashed and all settings reset to default.

If for some reason you made a mistake during the procedure and it doesn't reboot by itself wait 5 minutes before turning it off, just to be safe that it isn't still flashing the BIOS.
