BIOS package for the PRIME B460M-A desktop board, revision R2.0, with the name indicating both 8 MB and 16 MB images are included. B460 is an Intel chipset for 10th generation Comet Lake processors. Having two sizes matters because revisions may ship with different flash capacities, and an image that does not match the fitted chip will not program correctly. Read the marking on the SPI chip, choose the corresponding file, and save the original contents before flashing with a programmer such as a CH341A.
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 @afsbiosfree. Enginerys does not host this file.
