You need a flash drive formatted as fat (Right click on drive. Click format. Select fat for file system. Press start)
Down load the bios 3310 from here:
http://macles.blogspot.com/p/acer-aspire-one-bios.htmlExtract all files. Put both FLASHIT.EXE and the BIOS file with FD suffix
in the root directory of the flash drive. The files must not be in a
folder. Rename the BIOS file to
ZG5IA32.FD before proceeding. It only works with this exact filename.
Make sure laptop is off and has battery and power plugged in.Plug in flash drive to netbook. Press
Fn and
Esc simultaneously, keep them pressed and
press the power button. Release Fn+Esc after a few seconds. The power
button starts blinking at this point. Press it once. The netbook will now
access the files on the flash drive and initiate flashing the BIOS.
After a while the power button stops blinking, and the netbook reboots by
itself. Wait patiently.
If it doesn't reboot, but keeps blinking, wait at least a few minutes before turning it off, and try again.
