RAR archive with BIOS firmware for the HP Compaq CQ40 built on Compal mainboard LA-4103P. Compal labels its notebook boards with LA-xxxxP numbers silkscreened on the PCB, so read it there and compare before flashing, as the CQ40 shipped on more than one board. The small archive of under 1 MB likely contains the image for the SPI flash. Extract it, check the size against the chip, back up the original contents with your programmer, and then write and verify the image.
