BIOS archive for the ASUS X442UQ, board revision 2.0, a rar of about 5.63 MB. The name lists no version, chip type or EC content, so open it and identify each image before you program anything. Dumps like this are used to recover boards stuck on a black screen or boot loop after a failed update, written with an SPI programmer straight to the flash chip. Read and keep the original contents first, confirm the board revision matches 2.0, and make sure the image size equals the capacity of the chip on the board.
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.
