Which laptops use the DAX8MMB18D0 motherboard?

Which revision of DAX8MMB18D0 do I have?
Files for this board mention Rev D. The revision is printed on the PCB silkscreen, usually next to the board code. Pick files with the same revision when you can; if yours is not listed, the closest revision is usually fine for the schematic but check part positions in the boardview carefully.

Read the original chip with a programmer and save two copies before writing anything. A dump from another board carries that board's serial number and MAC address, so restore yours from the backup.
