Recently added DRAC5 card doesn't show up

Hi - I have a PE2900 that's been in production about 3 years.  I'm going to be using the server for a new project, and decided to install a DRAC card.  I got one at a discount on a DRAC5 card as a "new pull".   When it arrived, the cables were the wrong length, so I had to order the proper cables for a PE2900 - this proved to me that it did not actually come out of a 2900, but it's a DRAC 5, so it should still work fine, right?

Here's what has happened - I installed the card, and when the POST begins, it says that there are 2 Xeon processors, etc., and below that it says "Remote Access Controller Detected".  THen, it continues the POST process, and after it displays the RAID controller information, it waits for 40 seconds, then displays information about the "Base Management Controller".  I pressed Ctrl-E anyway just to try and configure it, but it looks like the system is responding as if it only has a BMC controller, although ti does show that it has detected the DRAC at the beginning of POST.

Once the system comes up, I can go into Server Administrator, but it still only seems to detect a BMC.

I have updated the BIOS, but nothing else so far.  I haven't tried to update any firmware in the box.  Am I missing something?  Is there something else I should have to do to "disable" the BMC, and cause the system to use the DRAC? 

Thanks!
