Working BIOS for the Compal LA-E131P motherboard, platform CAZ20, revision 2.0 (A01), with a build date of 2017-10-13, archived as a 9.90 MB RAR. The board code follows Compal's LA-xxxxP pattern, so the actual brand of the laptop may differ from the board maker. Use it to reprogram the SPI flash chip with a hardware programmer when the firmware is corrupt. Save a copy of the original contents before erasing, confirm the image matches the chip size, and verify the PCB revision.
