ZIP archive for the MSI MS-7398 motherboard, 3.27 MB. The name provides only the board number, with no revision or contents described, so extract it with any standard unzip tool to see what it contains. Typical content for MSI desktop boards includes schematic PDFs used to follow power rails and signals, or BIOS images for SPI reprogramming. MSI uses the MS-7xxx scheme for these boards. Verify the PCB revision first, and keep a backup of the original chip before writing anything.
