HP 15 notebook BIOS for the CSL52 platform on Compal board LA-F761P, compressed in a 4.42 MB RAR archive. The name gives no revision or version, so compare the board marking before use. Compal ODM boards follow the LA-xxxxP numbering, and HP used this one in its 15-inch line. A technician extracts the image and writes it to the SPI flash using a CH341A, RT809 or similar programmer when the machine will not POST. Back up the original chip and verify that the file size equals the flash capacity before programming.
