Which laptops use the DAGD1AMB8C0 motherboard?
File names in the catalog tie DAGD1AMB8C0 to the Sony Vgn-cr MBX-177A, Sony PCG-5J5M and Sony VGN-CR220E. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of DAGD1AMB8C0 do I have?
Files for this board mention Rev 2A and Rev C. The revision is printed on the PCB silkscreen, usually next to the board code.

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.
