DAX31MB1AA0 REV A i7-7500U WORKING BIOS 100%

BIOS .rar 17.7 MB Shared

Working BIOS dump for the Quanta X31 mainboard DAX31MB1AA0, revision A, taken from a unit fitted with an Intel Core i7-7500U processor and marked as 100 percent working. The DA prefix with MB in the number is the usual Quanta motherboard code. Use it to reprogram a corrupted SPI flash with a hardware programmer when the board shows no POST. Confirm the revision and CPU match your board, back up the original chip first, and verify the extracted image size matches the flash capacity before writing.
