BIOS firmware for an HP Pavilion DV4 on the Compal board LA-4102P, PM45 chipset variant, packed in a 788 KB RAR. LA numbers follow the Compal scheme, and the PM45 note indicates the discrete-graphics Intel version rather than an integrated one. Use it to reprogram the flash chip with a programmer when the board fails to start. Verify the LA number and chipset on the board, back up the original chip, and check that the image size matches the chip.
