I found a bootable cd. Boots ok and I can see two of my three drives listed in /dev. Also in bios setup. Plugged the suss drive back in and system stays up. Now I need to figure out mounting drives after a cd boot and how to scan for the suss drive.

Don't think cmos is bad but could be time to get a new battery just in case.
