Hi Shawn, as always you are correct thanks for the reply. I did a bit of messing around between 2 machines and the cabinet ID has no connection to the hard drive or update. The 8 pin security chip and hard drive have all the update information required. So you can also upgrade your machine by swapping these 2 two items from one machine to another. As you know The key item is the 8 pin chip from the I/o board, the hard drives are generic.
