BIOS image for the ASUS PRIME B450M-A motherboard, revision 1.01, marked OK as working. It is a raw 16MB .bin, matching a 128 Mbit SPI flash, ready to be written with an external programmer. Technicians use it when an AM4 board no longer posts, shows no video or is stuck after an interrupted update. Check the revision printed on the PCB, read and keep the original chip before erasing it, and confirm the chip capacity is 16MB so the image fits exactly, then verify after writing.
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 @bios_laptopomi. Enginerys does not host this file.
