Intel has two 64-bit architectures - you probably downloaded the disk for
the wrong one.  On one hand they have the IA64 architecture which they
originally intended to be the successor to the IA32 (aka x86 or i386) architecture.
IA64 never became very popular however.

AMD created their own 64 bit architecture -  AMD64 (aka x86-64) which had
the big advantage of being backwards compatible with the x86 architecture.

Eventually Intel too started to implement chips around the AMD64
architecture - except they called it EM64T.

FreeBSD supports both the ia64 and amd64 architectures.  Unless you have a
computer with an Itanium or Itanium 2 CPU (which you do not have) you want
to install the amd64 version of FreeBSD and not ia64. (Or the i386 version since that
will also work fine, albeit only in 32-bit mode.)
