Use USB Bootable flash drive with these alteranate bios recovery name : a. Get recovery name with phoenixtools : "AMIBOOT.ROM" and "UASL1.ROM" and do this hxxp:// forums . mydigitallife . info/threads/870-Bios-Recovery-Procedures. Still no luck. b. I found hxxp://www .helpowl. com/manuals/Acer/AT110F2/112300 , Acer AT110F2 service guide, It says that recover name is "FLASHABL.ROM". I use for recovery still no luck. 2.
