Unfortunately, Windows always wants to be the first OS on the first
drive. But there is a way to fool Windows into thinking it IS the
first OS on the first drive, even though it is not, as in your case.

I have a little more simple setup, but perhaps you could learn from it.

I have Ubuntu linux on the first (80 gig) drive. It possess the whole drive.

Win XP Pro is on the second drive (20 gig). It possess that whole drive.

My drives are not scsi or STAT, but I believe my grub setup will steer
you in the right direction.

The Ubuntu is straight forward for setting up Linux on a hard drive.
So I won't list it here.

Here is the Windows part for the second drive:

title		Windows XP
root		(hd1,0)
rootnoverify (hd1,0)
map (hd0) (hd1)
map (hd1) (hd0)
chainloader +1

The first map line fools my system into thinking that the first drive
is actually the second drive.

The second map line fools my system into thinking the second drive is
actually the first drive.

Now, Windows is fooled into thinking it is on the first drive and it
will boot and run as normal.

Best of luck to you.
