BIOS archive for the HP 15 model 15-r216tx, built on the Compal LA-B972P mainboard; no revision is given. The 4.35 MB RAR must be extracted, and the image compared with the flash chip capacity before programming. Compal identifies its motherboards with the LA-xxxxP format shown on the board silkscreen. Technicians use this to recover a laptop after a failed update or corrupted firmware, always reading and saving the original SPI contents first so system data can be reinstated.
