Hmm, according to CPU pages the T5600 is 64-bit capable (see
http://forums.anandtech.com/messageview.aspx?catid=29&threadid=2067695&enterthread=y&STARTPAGE=2),
but according to the 7.0 hardware notes it is not:

"
2.1 amd64

...

 * Intel Pentium(R) 4 Processor supporting Intel EM64T ("Prescott").
This is fabricated on 90nm process technology, uses FC-LGA775 package,
and operates with 3.20F/3.40F/3.60F GHz and Intel 925X Express
chipsets. The corresponding S-Spec numbers are SL7L9, SL7L8, SL7LA,
SL7NZ, SL7PZ, and SL7PX. Note that processors marked as 5xx numbers do
not support EM64T.
"

Yes, there are only two x's in the last sentence.  Does that refer to
another processor type?

Rene
