Slight correction, switching to Legacy Bios works. Note you must switch
back to boot something like Windows 8. In my case mine had the option to
support both, and default to UEFI. Note, Macs don't have this option so
they're still dead in the water without 64 bit.

Doing this I got v5.5 to boot, apparently that's the most current one I
have on a stick right now. I'll test 6.0 and 6.5beta tomorrow and then
go looking for a Mac to prove my theory.
