Hello,
Yes the ROM is all that you have to transfer to make the PCB compatible. On SATA boards this is all done through the SATA connection (for WD drives). I won't be back in the office until Monday to post a picture, but you can use the Samsung adapter on the USB models to read the ROM code. I know Bankie has a pic I shared in another forum, so maybe he can post the connection for you. Though on functioning drives you can often read it even through the USB via the utity.
