BIOS image for the MSI MEG Z490I UNIFY mini-ITX motherboard, board code MS-7C77, stored in a 19.6 MB RAR archive. The Z490 model belongs to the Intel 400-series platform, and MSI identifies its boards with MS-xxxx numbers printed on the PCB. Use the file to reprogram the SPI flash with an external programmer when the board is stuck after a failed update, or compare it with the factory image. Check the archive contents, back up the original chip, and make sure the image size matches the flash capacity.
