Compressed BIOS dump for the Acer Aspire ES1-520 series, linked to the Compal LA-D121P mainboard, though the short file name gives no revision, version or chip details. The 2.20 MB RAR is meant for recovering a laptop with corrupted firmware by reprogramming the SPI flash with a hardware programmer. Compal uses the LA-prefix numbering for its own board designs. Open the archive and check the image size against the chip on the board before writing anything, and keep a full backup of the original contents in case the dump does not suit your unit.
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.
