Compal AIA20 LA-B692P motherboard BIOS, revision 1.0, with a 2014-08-29 date in the name, provided as a 1.96 MB RAR archive. It is meant for the earlier production revision of this board, so it is not interchangeable by default with the later 1C release. Typical use is rewriting the SPI BIOS chip with an external programmer when the laptop has no POST or a corrupted firmware. Compare the board number and revision on the PCB, read and save the current chip contents, and check that the image size matches the 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.
