Frequently asked questions

Which laptops use the DAGD1BMB8B0 motherboard?
File names in the catalog tie DAGD1BMB8B0 to the Sony Vgn-cr MBX-177A, Sony GD1B and Sony PCG-5G2T. Laptops sold under one model name can use different boards, so confirm by the code printed on the motherboard.
Which revision of DAGD1BMB8B0 do I have?
Files for this board mention Rev 2A and Rev B. 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.
