Question Grub setup for SATA RAID array (FC3)


Hey, I apologize if this was already posted but I'm having a problem.

First off, I have Fedora Core 3.

I have 3 hard drives in my computer. 2 of them are SATA drives in a RAID-0 array. I don't use these for linux, they hold Windows XP. I have a 10GB IDE drive that I use for linux. I cannot get Grub to boot to Windows. I can boot to FC3 fine from Grub. When I try to select Windows, it gives me a "disk read error...hit ctrl-alt-del to restart your computer"

Grub is installed in the /boot directory.

I think I have mapped the SATA drive correctly in device.map. In the /dev folder, it shows the following:

sda
sda1
sda2
sdb

I have tried mapping each one but none work. Do I have to mount them somewhere? I am pretty much a complete noob when it comes to this so any help would be appreciated.

Here are how the files look:

device.map

# this device map was generated by anaconda
(fd0) /dev/fd0
(hd0) /dev/hda
(hd1) /dev/sda


grub.conf

title Windows XP
rootnoverify (hd1, 1)
chainloader +1

I'm probably just missing something little or stupid but any help would be appreciated, thanks.

If windoze is on the first partition of your RAID array then you could try:
Code:
title Windows XP
rootnoverify (hd1, 0)
chainloader +1
Hope that helps.

I assume that since you have a sata raid, that you wont need the "map" command. If you are still unable to get your setup to work, post back.

I still have yet to get my grub working...I also just upgraded to FC4 64bit and still no luck.

as stated in my original post, I have 4 sda drives in my /dev dir (sda, sda1, sda2, sdb).

in device.map, i have tried mapping all 4 to hd1 and in grub.conf have tried the following

In all cases if i put down

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

It displays:
rootnoverify (hd1,0)
chainloader +1
and does nothing.

If i put:
title Windows XP
rootnoverify (hd1,1)
chainloader +1
it says "disk read error...hit ctrl-alt-delete to restart"

My method of getting to Windows now is simply to go into BIOS and make my sata raid array the primary hard drive. It's annoying, but feasible, and I am looking to get grub to work to avoid that. It worked before on my old pc with the same raid controller so I know it is possible. Any ideas? I am a newbie so I'm still not very familiar with this stuff...I've been looking online and have found nothing that I could understand enough to know if it was a fix or not so please help. Thanks.
