BIOS firmware for an HP Compaq Presario CQ45 AMD-platform laptop built on the Compal LA-4111P motherboard, compressed into a 783 KB ZIP. The LA prefix marks Compal's board numbering; HP used several Compal designs for CQ45 models, so check that LA-4111P appears on your PCB. Technicians write images like this to the SPI flash with a programmer to revive a board after a failed update or corrupted firmware. Back up the original chip before flashing and verify that the image size fits the chip capacity.
