Small 215 KB RAR archive for Apple 820-2274, also tagged 051-7448 and A000, with LIO in the name. Apple pairs 820 board numbers with 051 schematic numbers, and A000 looks like the revision code of the drawing. LIO most likely refers to a left I/O daughterboard rather than the main logic board, so expect a small schematic. Use it to check ports, connectors and the flex lines back to the main board, and match the board number on the PCB first.
