ASUS K42JR BIOS for board revision 2.0, packed in a 7.24 MB RAR and labelled as a fully working image. Use it to recover a laptop that powers on without POST because of corrupted firmware. After extraction, check the file size against the SPI flash chip on the board, read and save the original contents with a programmer, and confirm the mainboard revision silkscreen shows 2.0. Restoring the model serial and other data from the original dump may be needed afterwards.
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.
