BIOS package for the Acer Aspire One AOP531h netbook, listed as AOP531p in the name, compressed into a 789 KB RAR. The name gives no version, board number or chip capacity, so open the archive and check the image size against the flash chip on the board. Such dumps are used to revive netbooks with corrupted firmware, often by programming the SPI chip directly with a CH341A. Always save a read of the original chip before writing, and verify the write afterward.
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.
