That goes for most OS out there. If the boot record are at a certain 
.... (fill in the rigth unity and value) then the system simply don't
startup. FreeBSD has some filesystems that you wanna have a the front
of the disk because of the performance. I recond the best thing to do 
is create tree or four partions. Two for FreeBSD and one or two for 

The first partions holds / (128M) , the swap (2x mem, of 1x mem if you 
got two disks) and /var (256M). The secord partion hold the XP fs. The 
thirth hold the rest of FreeBSD fs and the fourth old more for XP if you 
are likly to experiance problems. (aka have the second partion in the 
dainger zone)
