BIOS dump for a laptop mainboard labelled FH5AT, board number LA-K091P revision 2.0, packed in an 11.7 MB RAR archive and marked as fully working. The LA- prefix follows Compal numbering, so the board was built by Compal regardless of the brand on the lid. Technicians write such an image to the SPI flash chip with a programmer such as a CH341A when the original firmware is corrupt. Confirm the LA number and revision silkscreened on the PCB, and save a backup read of the existing chip before erasing it..
