BIOS image for an ASUS AMD board DANJMMB1AA0 revision A, from 2021, with a Ryzen 7 processor and an NVIDIA GN20-E3-A1 GPU variant noted in the name. The DA prefix with MB in the number follows the Quanta scheme, the ODM that produced this mainboard. The rar archive is about 11.6 MB. Technicians use it to reprogram the SPI chip on boards that no longer post. Check that the board number and revision on the PCB match exactly, confirm the GPU variant, and save a copy of the original flash first.
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.
