Not booting after raid cont replacement

Hi.. Here’s the problem

1) You perform a cold backup using veritas of a Win2k server.
2) You install Win2k and veritas on a new server with different hardware.
3) You perform a complete restore on new server
4) Server no longer boots because of the different raid controller drivers.

Now I have been searching the ‘net and found a MS technote that explains how to change a raid controller driver using registry editors and ERD disks. This was tried several times without sucess.

Any ways forward.
