BIOS image for the Compal board LA-C831P, revision 3.0, compressed into a ZIP of 8.44 MB, a size that suggests a full SPI flash dump of around 8 MB. Technicians write such dumps to the BIOS chip with an external programmer to fix boot failures, corrupted firmware or password locks. Always read and save the original chip first, and compare the image size with the flash capacity, since a mismatched dump will not fit. The board number and revision printed on the PCB should match the name.
