BIOS dump for the HP 15-ay000ur laptop on Compal board BDL50 LA-D702P, archived as a 3.64 MB RAR. BDL50 is the Compal project code and LA-D702P the board number printed on the PCB; the extra word in the name appears to mark it as the uploader's own dump, read from a working unit. Write it to the SPI flash with a programmer to recover a board with corrupted firmware. Check the board number matches, save the original chip contents, and restore the serial and product data afterwards if needed.
