Working BIOS image for the ASUS K52JC laptop, board revision 2.0, packed as a 1.75 MB RAR archive. The dump is meant for restoring the motherboard SPI flash with an external programmer when the notebook shows no image, will not post or has failed a firmware update. Extract the archive and compare the file size with the installed flash chip before writing. Keep a backup of the original chip contents, and check that the revision printed on the PCB reads 2.0, since other K52JC revisions have their own images.
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.
