dual booting

[budman7]

I am attempting to get grub to boot DesktopBSD and I am not having any success.
I put BSD on the slave drive, I was hoping for the option to install the BSD loader to the root partition, but sadly, I don't get that option.
I googled for "grub freebsd", but the results don't produce understandable info.
If someone could explain the naming scheme for BSD partitions.
I have DesktopBSD on /dev/hdb1.

I did manage a partial fix, using the BIOS to select which hdd to boot to, but this is a PITA.
I found this guide for booting BSD with grub.
http://tips.enderunix.org/view.php?id=70&lang=en
I was hoping that I could get grub to install, then it would be much simpler to chainload it. But, this didn't work either.
As suggested in the guide, I looked in /boot/grub/device.map to make sure that /dev/rad1 is there instead of /dev/ad1.
I do not have /dev/rad1, I have /dev/ad1. And I get this error

localhost# grub-install /dev/ad1

Problem solved.
I attempted to install grub to /dev/hdb1.
I think during that attempt I borked my DesktopBSD boot loader.
So I went and reinstalled it.
Now this entry in my Suse grub works fine

root (hd1,a)
