BIOS dump for the HP EliteBook 8440p on Compal motherboard LA-4902P, revision 1.0, given as an 8 MB image with no file extension. LA-xxxxP is the Compal numbering pattern, printed on the PCB along with the revision, and both should match before flashing. An 8 MB image fits a 64 Mbit SPI chip. Technicians use it to revive a board with corrupted firmware by programming the chip directly with a CH341A or similar tool, reading and saving the original contents first.
