BIOS file for the Acer Aspire One D255 netbook, labelled AOD255, delivered as a RAR of 793 KB. The name carries no version, motherboard number or chip capacity, so verify these from the archive and the board itself. A common use is recovery of a unit that powers on without display, by writing the dump to the SPI flash with a programmer such as CH341A. Keep a backup of the existing chip data, and confirm the file size equals the chip size before flashing.
