BIOS release 1.02 for the ASUS PRIME Z270-AR desktop motherboard, an Intel Z270 platform board, supplied as a ZIP of about 8.2 MB. A version file like this suits recovery of a corrupted SPI chip, either through a programmer or the board's own flash utility if it still posts. Keep in mind that a clean vendor image lacks the board's serial and MAC data, so dump the original chip first and transfer those identifiers where needed. Verify the exact model on the board before writing.
