Firmware set for Compal LA-7871P, labelled QAL31 with the extra tokens 50 and 51, likely referring to variant or chip designators that the name does not explain. The roughly 2.9 MB archive should contain SPI dumps intended to be programmed with a hardware flasher when the board fails to post or the BIOS is corrupted. Because Compal boards are sold under several brands, rely on the LA-7871P marking printed on the PCB, save a read of the original chip, and make sure the image size equals the chip capacity.
