ASUS X540UBR revision 2.0 BIOS for boards fitted with an 8th generation Intel processor, supplied as a 6.73 MB RAR file containing an 8MB image reported as fully working. A separate version exists for 7th generation CPUs, so check the processor on your board and the revision marking before use. Technicians flash such dumps directly to the SPI chip with an external programmer to fix corrupted firmware or no-boot issues. Always back up the existing chip first, and verify the image size equals the 8MB flash capacity.
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.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
