Nope, haven't played around with the partitions at all. I really wanted a reference image out of the box, but when I saw Imagew trying to capture 55,000 MiBs I knew something was up.
Having a USB Gig NIC might help, but I thought I read something on Dell's site that not all USB NICs will work with that hardware and they were coming out with a specific dongle for this purpose. Also, it's hard to schedule multiple bare metal machines for Provisioning if they are sharing the same USB dongle (have to precreate the records with a unique ID and I didn't have luck using Serial Number). Capturing the image would work fine in this manner though so might be worth a try. Just wish I knew why it was trying to capture the whole drive.
