windows 2003 to 2008 upgrade failed (SCSI driver) how best to get a command prompt or use the Rollback partition

Upgrading a Proliant from 2003 to 2008. It hangs on first reboot, I think because of a SCSI driver. (HP suggests Remove lsicsb6.sys)
I don't get the rollback option on reboot, but if I boot from the Windows 2008 CD, and choose repair, I do see the rollback partition, as well as the Windows partition

How do I either:
Acticvate the rollback partition.
Get a command prompt (lsicsb6.sys loads before the command prompt in safe mode with command prompt)

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Founs the command prompt which appears after selecting a partition to recover.
Got rid of lsicsb6.sys and the upgrade is continuing.
However if someone can tell me how to force a rollback, that would be interesting.
Usually there is an option in the bootloader (that's what I've seen in 2003 -> 2008 upgrades)

Assume that you don't see because of the SCSI driver!

Indeed, hence needing help. I stopped for lunch but will go back and see how it is doing...

I fixed it myself, there was a SCS controller problem and then the teaming on the NICs was borken and then a NIC was trying to authenticate against the IAS server I had previously removed. Generally a mess
