BIOS for the Biostar P41D3 desktop motherboard, version 6.2, sized at 1MB for an EN25F80 flash chip, which is an 8Mbit SPI part from Eon. The small RAR archive holds the image for restoring a board left dead by a failed update or corrupted firmware. An EN25F80 is supported by most common programmers, though some need the device selected manually. Confirm the 6.2 marking on the PCB, dump the original chip before writing, and make sure the extracted file is exactly 1MB.
