BIOS image for the ASUS UX430UQ ultrabook, board revision 2.0, described in the name as a fully working dump. The RAR archive is about 8.06 MB, which suggests a full SPI flash image rather than a capsule update file. A technician writes it to the BIOS chip with a programmer such as a CH341A when the laptop shows no POST, a black screen or a corrupted firmware. Before flashing, back up the existing chip contents and check that the image size equals the flash capacity and that the PCB revision matches.
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.
