RAR archive with a 16 MB BIOS image for the MSI X470 Gaming Plus desktop motherboard, model code MS-7B79, an AM4 board on the AMD X470 chipset. Use it to reprogram a corrupted SPI flash chip with an external programmer when the board fails to post or loops on power-up. The name does not state a BIOS version or PCB revision. Read and save the original chip before writing, and check that the chip is 16 MB. MSI's own update files may need conversion before you burn them raw.
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.
