I didn't either, but the vast profusion of CPUs that Intel calls "Xeon" 
makes matters very confusing.

Do you know the CPU model number?  (I suppose you could take the machine 
apart and read the chip, if nothing else.  See 
http://support.intel.com/support/processors/sb/CS-028738.htm)  Or is there 
possibly some useful information printed by the BIOS at boot time?  Once 
you have a number, http://processorfinder.intel.com/ may be of help.

Intel also has their own identification utility at 
http://www.intel.com/support/processors/tools/piu/index.htm .  There's a 
Windows version as well as a bootable version.  (The bootable version 
claims to be OS independent but the download is an EXE file, so I'm not 
sure how that is supposed to work.)
