BIOS package for the PRIME B460M-A motherboard, board revision 2.0, with 8 MB and 16 MB mentioned in the name, suggesting images for two flash chip sizes. The 9.05 MB zip is intended for writing to the SPI chip when the board fails to post or after a failed update. Identify the chip fitted on your board and choose the image whose size matches it, since an image of the wrong length will not fit. Read and save the original contents with a programmer before writing, and confirm the revision on the PCB.
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.
