I think the problem here is that some of us have been talking about Core 2
Duo chips being 64 bit capable, however, the OP has a T2500 chip which is a
Core Duo chip and not a Core 2 Chip and therefore it is not 64 bit capable.

Nonsense. The manufacturer is not going to list drivers for x64 just on
the chance a customer might upgrade a cpu. They are listing drivers for
the machine in factory condition. Show me a Core 2 Solo, Duo, or Quad
that is not a 64-bit cpu. Only the Core Solo and Duo are not 64-bit.

Then why does Dell list Vista x64 drivers for the D820? I never heard
of an Intel Core 2 Duo, Centrino or otherwise, that was not 64-bit.
Where did you get the info that this machine was not 64-bit capable?

Go to

http://www.intel.com/cd/channel/rese...sors/index.htm

and you'll see that Intel Extended Memory 64 (Intel EM64T) is NOT a
feature of the T2500.

Dell includes 64-bit drivers because a 64-bit capable CPU is optional in
the D820.
Unfortunately, you didn't get one of the higher-end processors.
