BIOS image for the HP Envy Ultrabook, Compal project VBU50 on mainboard LA-9512P, in a 3.73 MB RAR archive. Compal pairs a four- or five-letter project code with the LA-xxxxP board number, both usually printed on the PCB. The dump serves to reprogram the SPI flash with an external programmer after a failed update or corruption. Read and save the existing contents before writing, compare the image size with the chip capacity, and check that the LA number on your board matches exactly.
