That has always been one of the cool features of FreeBSD. If you specify only 
the default CFLAGS and don't take advantage of cpu features, you can drop the 
HDs from a Celeron into an AMD 2400+ XP and have it run out of the box. I had 
a voltage regulator blow last week and fry a mother board and all pci cards. 
I'm not sure what went first but when it exploded and sent shrapnel past me 
into the room it got my attention. I expect to replace the mobo with a new 
cpu and pci cards and have it boot on the first try. The only problem will be 
reconfiguring the video card. The old Geforce 2 was no longer available.
