BIOS for the MSI PRO Z690-A WIFI DDR4 motherboard, MSI project number MS-7D25, provided in a RAR archive of about 26.5 MB. No firmware version or tested status is given in the name. MSI uses MS-xxxx codes to identify its boards, and that number is printed on the PCB, so confirm it matches before flashing. The image can be written to the SPI flash with a programmer to recover a non-booting board; read and save the original chip contents first and make sure the image size fits the chip.
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.
