Firmware archive for the ASUS X409DL motherboard, revision 2.0, in the discrete graphics (DIS) variant, with an 8 MB BIOS image. The DIS marking matters because UMA and discrete versions of the same board use different firmware, and mixing them can cause no-display faults. An 8 MB file matches a 64 Mbit SPI chip, usually programmed off board or with a test clip. Confirm that the board revision and graphics configuration match the PCB, and save a read of the original chip before writing anything.
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.
