Conversion details for the Dell XPS L502X built on the Quanta GM6C platform, with MLK and UMA noted in the name, archived as a 2.19 MB RAR. The material targets turning the board into integrated-graphics operation, typically through component removal, strap changes and a matching BIOS. Quanta boards carry DA0 style numbers printed on the PCB, so check that the board and revision match before modifying anything, and save a dump of the original SPI flash first.
