Working BIOS image for the ASUS X407UBR laptop at mainboard revision 2.0, marked as fully tested. A dump like this is used when the firmware is corrupted and the laptop shows no POST, a black screen or a boot loop: the SPI flash chip is reprogrammed with a CH341A or similar programmer. The archive size is 16.8 MB, so check what the image file inside it is. Back up the original chip, check the image matches the flash capacity and confirm the revision on your board before 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 @biosarchive. Enginerys does not host this file.
