BIOS for the MSI A320M-A PRO desktop motherboard, MSI board code MS-7C51, with the name indicating version 16. It comes as an 8.56 MB RAR archive. MSI uses MS-xxxx numbers to identify its boards, and the code is printed on the PCB. Technicians use the file to recover a board stuck in a no-POST state, either through the programmer route or a flashback feature. Confirm MS-7C51 is printed on the board, keep a copy of the original chip contents, and verify the image size matches the flash chip.
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.
