I have tried numerous tests of formatting the drives on the RAID, then moving them to another system and installing the software.  They still won't boot.  The RAID appears to be using a very unusual bootstrap.  I get the message "OS not found"  continuously on the screen regardless of how I build the system.  Somehow I am going to need to be able to boot from CD or memstick to get this working.

is the other system identical to your system? If you move disks from one RAID controller to another RAID controller, the success depends on many more factors than just the proper plugs.

Isn't there a way to boot the machine without RAID?
