BIOS backup for an ASUS X455LD mainboard, revision 2.3, in the UMA variant that relies on integrated graphics instead of a discrete GPU. The name marks the dump as OK, meaning it was reported working. The 3.35 MB RAR archive needs extracting before the image is loaded into programmer software and written to the SPI flash. Check that the board revision and graphics configuration printed on the PCB match, and keep a copy of the original chip contents before you erase 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.
