BIOS archive for a Compal LA-994P board, revision 2.0, with ZS050 as the Compal project code; the laptop brand is not given in the name. Compal numbers boards LA-xxxxP and pairs them with short project codes. The dump is meant to restore the SPI flash when the machine is dead, has no display or fails after a bad update. Confirm the board number and revision on the PCB, check the image size against the chip, and back up the original contents first.
