64 bit download for Intel Pentium

[james gray <windzebragrass@gmail.com>]

i have looked at the information available for downloads and do not see a designation for 64 bit intel.

i have installed 32 bit squeeze and it works , yet is slow.

does any one have a suggestion for a download for the 64 bit, Intel Pentium B960 @ 2.20 Ghz.

I am working with a:

HP

Pavilion G4-1318dx

Thank you in advance
