2000 only shows 2 CPUs because it cannot take advantage hyperthreading. >From what I have read (Intel's website, some others), hyperthreading requires both BIOS and OS support to be utilized. Currently, XP and the newer Linux releases are all that I have seen that will take advantage of it.
My research on this was fairly light since I was just after can Redhat Advanced Server support it, but I do remember seeing that W2K would not. -- Michael Brown Glen Raven, Inc./Info Services Senior Oracle DBA 1831 N.

The Windows 2000 family counts each hyper thread as 1 CPU. In contrast, Windows XP and Windows 2003 Server count each CPU instead of each hyper thread. Thus, the task manager in Windows XP Professional show 4 CPU's (on a dual XEON CPU computer with hyper threading enabled) while Windows 2000 Professional only shows 2 CPU's in the task manager.
