Hi....I purchased this server (8658) and have been successful in upgrading memory, but am stuck adding second cpu. I picked up a slot 1 800eb, but when installed I get a "VRM" error. Now, according to chart on side panel there is no "VRM" installed. Yet....the server will work fine with single cpu and terminator in second slot. I'm new at IBM stuff...can someone please advise me on what to do? Thanks in advance.
