BIOS firmware for the MSI Z370 PC PRO desktop board, model code MS-7B49, compressed as a RAR archive of about 20.5 MB. The name does not say whether it is a full SPI dump or a vendor update capsule, so inspect the contents and compare the image size with the flash chip before programming. A full image can be written with a CH341A or similar programmer to recover a board with corrupted firmware. Always read and save the original chip contents first, as they hold the board's own serial and MAC data.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
