Tested working BIOS image for board LA-D562P rev 1.0, with the platform code BIWP4-P5, supplied as a 4.28 MB RAR. BIWP4-P5 is the code printed on the PCB next to Compal's LA-xxxxP number. Use it to reflash the SPI chip when the board will not power on or show a picture because of corrupt firmware. Read and save the existing chip before writing, check that the image size matches its capacity, and confirm the board revision is 1.0, as other revisions may need a different dump.
