Hi All,
      Does Mac OS X 10.5 provide separate 32-bit and 64-bit kernels
?Or there is only one type of kernel supported.

What I mean is that like Windows has separate version x86, x86_64, IA
is there something like this for Mac OS X 10.5 as well ?

If not are there only 2 version:
Intel i386 and PowerPC ?

and does the same thing run on 32-bit and 64-bit hardware ?

Most (if not all) of the answers are in the 64 bit Transition Guide and in The Universal Binary programming Guide.
