RAR archive of about 1.13 MB covering FIC MR055 and MR056 boards at revision 0.2. FIC (First International Computer) was a Taiwanese ODM that built notebook and desktop boards for other brands, so the MR code on the PCB is the key identifier. The low revision number suggests an early design stage, and production boards may differ in places. Expect schematic pages useful for tracing power rails, locating regulators and test points, and isolating shorts. Confirm which of the two models you have before using it.
