BIOS for the MSI Z170A KRAIT GAMING motherboard, board version AB, provided as a 6.66 MB ZIP. The Z170 chipset in the model name places it on Intel's Skylake desktop platform. Technicians use such a file to reprogram the SPI flash with a CH341A or similar programmer when the board fails to post after a bad update. Check the PCB version marking matches, confirm whether the file is a full chip dump or an MSI update file, and save the original chip contents before writing so you can roll back.
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.
