ACER Aspire One Cloudbook 11 AO1

BIOS .rar 3.37 MB Shared

BIOS firmware for the Acer Aspire One Cloudbook 11 (AO1 series) laptop, supplied as a 3.37 MB RAR archive. The name does not list a board number, revision or firmware version, so identify the motherboard code on the PCB and compare it with the contents before use. Technicians use such a dump to recover a unit that powers on without display or fails after a bad update, writing it to the SPI flash with an external programmer. Read and keep the existing image first, and ensure the file size equals the flash chip capacity.

The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
