|"I tried to restore from OEM recovery CD w/o success."|
That sounds like a factory image recovery. You go into recovery console before you do such a drastic measure. What was the error(s) that prevented you from completing?
" I got to RAID setup once and reset."
Whoa there! That was diffinately the wrong thing to do. What exactly do you mean by "reset"? Remove the array?
" Then the system wouldn't reinstall because it didn't recognize the hard drives."
You have to present install with the raid controller drivers. Since you didn't the install wouldn't see the drives
" I haven't been able to get back to RAID setup"
You have to start here. You can't move on to installing anything until you have the raid array set and the drivers available.
