MSI desktop BIOS package labelled Z170A GAMING with board number MS-7923 version 1.0, compressed as a 6.21 MB RAR. The model name and the MS number in the file name may not correspond to the same product, so check the silkscreen on the board before use. MSI marks its boards as MS-xxxx with a revision on the PCB. Extract the image and write it to the SPI chip with a programmer to recover a board that fails to post. Keep a backup of the original chip so the serial and MAC data can be restored.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
