BIOS firmware archive for the Asus X442URAS-series laptop mainboard, revision 2.0, packed as a 4.11 MB RAR. The name gives only the board model and revision, so open the archive to see whether it holds a full SPI dump or just a BIOS region. Technicians use such images to recover a board that no longer posts after a corrupted update, writing the file to the SPI chip with a programmer such as CH341A. Confirm the revision printed on the PCB matches 2.0, read and save the original chip contents first, and check the image size against the 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.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
