BIOS package for a board identified as APW5U with the Compal number LA-C401P, including images for both an 8 MB and a 16 MB flash chip. No laptop brand is given in the name, though APW5U looks like a Compal project code. Systems with two SPI chips split firmware between them, so each image must go to the chip of matching capacity. Read and save the existing contents of both chips with a programmer before writing, and verify the board number on the PCB.
