MSI H510M Bomber desktop motherboard BIOS, model code MS-7D22 version 1.2, sized for a 32 MB flash, compressed in a 9.26 MB RAR. MSI desktop boards use MS-7xxx codes, and the version is printed near the PCIe slots, so make sure it matches. A 32 MB image requires a 256 Mbit chip. Back up the original with an SPI programmer before writing, and verify after flashing, since a mismatched image can leave the board without POST.
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.
