Olympus Wistron board 07258-1, PCB part 48.4Y603.0SA, packed in a RAR archive of roughly 1.28 MB. It covers revision -1 of the design, while a sibling archive covers revision -3. Its contents are not stated, so open it to see whether it is a schematic, boardview or BIOS. Wistron uses this five-digit-plus-revision numbering, commonly on Acer machines. Revisions can differ in parts and nets, so check the silkscreen on your board before tracing rails or flashing anything.</p>
