BIOS or firmware image for the Pegatron PMSB-VH1 motherboard, revision 1.01, packed in RAR. Pegatron builds boards for OEM desktops and laptops, but the name does not say which branded system this board went into, so identify it from the PCB markings. The image is meant for reprogramming the SPI flash chip with an external programmer after corruption or a failed update. Back up the original chip first and make sure the image size matches its capacity.
