root seems to be incorrectly set after install

[George Lengel <lengel1@comcast.net>]

Hello,

I have a problem with my grub2 installation. I am using the latest 
Debian package (1.95+20080128-1)and I could properly boot using the 
chainloader method suggested during the initial installation 
(grub-legacy still in MBR and it calls grub2), but when I decided to 
place grub2 in the MBR, it will not work.

I have a bit of a complicated disk setup. My hd0 is the BIOS boot disk, 
but /boot/grub resides on (hd2,7).  I also have partitions spread all 
around my three drives with various OSs that I have not cleaned up 
(OS/2, DRDOS). I try to put grub2 in the MBR using grub-install (hd0) 
and then also try grub-setup directly and the setup almost works.

When I reboot I get thrown into rescue mode and typing set shows
grub>prefix= (hd0,7)/boot/grub
grub>root=hd0,7

If I manually set root to (hd2,7) and prefix to (hd2,7)/boot/grub I can 
insmod normal and then running normal proceeds perfectly. It makes no 
sense to me why it is prepending hd0 instead of hd2. I have searched all 
over for a solution and the closest I came was someone a few months ago 
posted a similar problem. It was suggested to delete system.map and 
regenerate it, but this did not help.

Here is my device.map which makes sense to me
(fd0)    /dev/fd0
(hd0)    /dev/sda
(hd1)    /dev/sdb
(hd2)    /dev/sdc

and here is the output of grub-setup when I manually run it trying to 
get the proper file in the MBR. It clearly understands the root should 
be hd(2,7), but when it boots it seems to change it to hd(0,7).
