BIOS firmware for the Asus X541NC laptop motherboard, revision 2.1, supplied as a 5.54 MB RAR archive. It is useful for reviving a board that stays dark, loops at startup or lost its firmware during an update. Program the SPI chip with a CH341A or similar programmer after reading and archiving the existing contents. Confirm the board revision on the PCB reads 2.1, as Asus often changes layouts and firmware between revisions, and ensure the image size matches the flash chip.
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.
