Ok .. just purchased a used Dell PowerEdge 6850 on Ebay.  4 CPUs at 3.16
GHz.  I purchased it to make a computational box out of it ... wanting the 8
cores and lots of memory.

Now ... I put VMWare ESxi 4.0 on it and was installing a 64 bit version of
Scientific Linux.  During the install ... it tells me that I can not install
a 64 bit version ... and that I should install a 32 bit version.

The CPU details are listed below ... I THOUGHT these were 64 bit CPUs ...
did I mess up?  

3.16GHZ INTEL XEON-MP 667MHZ SOCKET 604 1MB SL84U

Thoughts and comments welcome.  Thanks in advance.
