Thanks Steve,

So USB2 from a PC should work, which is good.    I had problems  
booting FreeBSD 7.1 from even the internal drive on the mac mini until  
I partitioned it with MBR (as opposed to GUID)..   I tried installing  
to a USB drive last night, but it doesn't seem to show up when I hold  
down option while booting (that normally shows all bootable drives).   
I was hoping if anyone has done this for some pointers.
