Grub Raid5

I finally replaced my X-Fi so I can get sound on Linux   But now I've gotten Vista installed with all of my games, and I don't particularly want to have to go through all that again.  I currently have 6 hard drives arranged as such:
0.0 - 320GB
0.1 - 500GB
1.0 - 500GB (where I plan on installing Arch)
1.1 - 160GB \
2.0 - 160GB  } Semi-hardware RAID5 with vista installed. (Motherboard chipset's Raid5, 680i is the chipset)
2.1 - 160GB /

I can easily switch around any of the non-RAID drives if its necessary.  I was wondering what configuration I would have to use in GRUB to boot off of the RAID5 so I would still be able to get to Vista for gaming.

To install Arch I was planning on just unplugging all hard drives excluding the 500GB I planned to install on (I don't want to lose any data, so this seems the easiest way to make sure its installed to the correct drive, unless someone has a better suggestion).

Thanks in advance to whomever can help me.

Re: Grub Raid5

I assume you are using the BIOS RAID driver for windows vista. I am currently using this for raid-0 of two disks and dualbooting arch and win xp. In linux this is most likely accomplished by dmraid (installing both systems on the same raid set). There is a wiki describing how to do this, however i don't know if dmraid supports raid-5.

http://wiki.archlinux.org/index.php/Ins … _Fake-RAID

Aha, now that I really read your post I realize this will not help you directly. Wiki could still be useful thou.
Sorry for confusing stuff

Anyway, my grub config:
==============================
timeout   5
default   0
color light-blue/black light-cyan/blue

title  dmraid arch
root   (hd0,0)
kernel /vmlinuz26 root=/dev/mapper/nvidia_ejebcchf5 ro vga=795
initrd /kernel26.img

title MS microborg xP
rootnoverify (hd0,1)
makeactive
chainloader +1
==============================

Where hd0 is my first raid-set and Win XP is located on the second partition of this set. This should help you decide what numbers to use depending on the harddisks order.
