Windows 2003 SBS Says I have more than two processors, but I only have two.

Today I installed Windows 2003 SBS on a Dell Poweredge 2650 server with two Xeon 3 gHz processors.   The SBS installation program issues a warning:

This computer has more than two processors.  It goes on to warn that it will not use more than two processors.

According to the BIOS setup (and to my physical inspection) the server has only two processors.

This is the second Dell Poweredge on which I've observed this problem.

Questions:

(1) Why does SBS see more than two processors when there are, in fact, only two?

(2) Will it use both processors?

I found this on the Microsoft website:

(1) It reads dual core processors as being two separate processors, hence my systems have looked like four.

(2) It will use both processors.

ignore the warning. Hyperthreading is turned on and the OS sees it as 4 processors. It will drive on happily despite the warning
