BIOS image for the ASUS K42Jr, board revision 2.0, with the Intel Management Engine region cleaned, supplied as a 1.50 MB ZIP. A cleaned ME region avoids problems such as a laptop shutting down after a set time or failing to boot after a chip swap. Program it onto the SPI flash with an external programmer. Make sure your board shows rev 2.0, back up the original contents in case the serial or LAN data needs copying, and confirm the image size matches the 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.
