Tested BIOS for the Scorpius mainboard, revision A, Wistron board number 16515-1, supplied in an 8.11 MB RAR. Wistron identifies its laptop boards with this five-digit dash numbering. Use the dump to reflash a corrupted SPI chip on a board that will not power on properly or post. Extract it, read and save the original chip with a programmer, ensure the number and revision printed on the PCB match, and confirm the size equals the flash capacity.
