I don't think there's a basic problem if you run a 32 bit OS on a 64 bit
hardware. AFAIK the AMD64 platform is backward compatible with 32 bit OSs.
W2k is running fine on a AMD64 machine here, and there are absolutely no
problems.

In one of his earlier posts David mentioned that there were no problems when
he was running WXP on that machine.

I would rather expect some possible problems if you run a 64 bit OS (WXP x64
or Vista x64) on a 64 bit hardware, and then run a 32 bit application under
that 64 bit OS, if the 32 bit compatibility layer of the OS has not been
implemented properly.

I don't think it would make much sense (or would be even possible) to run a
program compiled for a 64 bit target OS on a 32 bit OS, just because the
hardware is 64 bit.
