FreeBSD on first hard drive - Windows on the second, configuring

[Chuck McManis]

I don't believe you can configure Windows to boot on anything other than 
what the BIOS believes is disk 0 (aka Drive C), so set it up such that 
Windows is on the "first" drive and FreeBSD is on the second, and have the 
boot manager or Grub or whatever set up to boot from the other drive.
