I've heard this idea a few times in answer to my question. Is there a 64 
bit Intel distro I'm missing? I saw someone suggesting I use the AMD64 
version, but when I attempt to boot that from the install disk I get 
some debugging output and a message saying "BTX halted" - I suspect that 
means I can't follow that suggestion...

Thanks again for all your help!
