I manually edit grub.cfg and add for OS that use their own boot loader a
chainload, e.g.

menuentry "FreeBSD"{
    set root=(hd0,msdos1)
    chainloader +1
}

menuentry "XP"{
    set root=(hd1,1)
    drivemap -s hd0 hd1
    chainloader +1
}

If you want to use grub with the automatically thingy and the
automatically generated grub.cfg shouldn't work anyway search the web
for explanations, how exactly a chainload does work and what to consider
to get your Windows version booted.
