BIOS firmware for the MSI Z490-A PRO desktop motherboard, model code MS-7C75, revision 1.1, stored in a 16 MB RAR archive. MS-7xxx codes are MSI's internal board numbers and are printed on the PCB, which makes it easy to confirm a match. Program the image into the SPI flash with an external programmer when a board fails to post after a bad update. Back up the original chip first to keep the MAC and serial data, and confirm the image fits the installed flash capacity.
