BIOS firmware for an HP Pavilion dv7 laptop using Compal board LA-4091P, packed as a 770 KB RAR archive. The image is meant for restoring a corrupted or locked BIOS by writing the SPI flash chip directly with a hardware programmer. LA-xxxxP numbers identify Compal-designed motherboards. Verify the board number on the PCB, since dv7 models were built on several platforms. Make a full backup of the original chip, and make sure the extracted file size equals the chip capacity before flashing.
