BIOS image for the Pegatron APM80-D3 desktop motherboard, version 0500, compressed in a 565 KB rar. Pegatron produces OEM boards for many branded PCs, so the same board may appear under a different system name. The file is useful for restoring a board that will not POST because of a corrupt firmware chip, written with an SPI programmer. Verify the APM80-D3 label on the PCB, compare the image size with the flash part, and back up the current chip contents before erasing in case model data must be kept.
