Dual Booting FreeBSD

[germain at purdue.edu]

Hello,

      I have recently come into possessing a new hard drive which is 40 gigs.  
I also have a 160 Gig hard drive with an unformatted partition that is approx. 
40 gigs.  Would it be easier to install FreeBSD on the unformatted partition 
or the new hard drive for the purpose of dual booting with xp?  Also, does 
anyone know how to set up a dual boot system or know of a good guide to doing 
so?

Thanks in advance,
Edward Germain
