newbie needs help with freebsd and grub

[Dan Hassell]

Hello, I have not been able to get grub to boot freebsd.  I have 
Win2000pro and Linux in partitions on the first hard drive and have been 
using a grub on a floppy to get a boot menu.  I don't want to mess with 
the MBR or anything as this computer is shared with others.  The win2k 
and linux partitions boot cleanly.

I have now added freebsd on a second hard drive.  It installed from the 
CD without incident.  I gave it the entire drive and chose the automatic 
configuration of slices etc.  Root is ad1s1a, swap is b, /var is d, /tmp 
is e, and /usr is f.  I did not add a boot loader from the install since 
I thought I didn't need to with grub.  In grub I went to the command 
line and gave it --

root (hd1,a)
kernel /boot/loader
boot

as recommended.  It returns "Filesystem type unknown, partition type 
0xa5"  After the kernel command it says "Error 17, Cannot mount selected 
partition."  Using root(hd1,<tab> lists the partitions a to f as above. 
So what's the deal?  I have searched in the docs etc. and come up dry. 
 Any help is appreciated.  It is a eMachines 600 mhz celeron with 128 
mb sdram if that matters.
