grub.conf / dual boot redhat 9 and WinXP

Hello,

My guess is that this question has been asked hundreds of times and will thus be an easy 250 points for someone :)  Enjoy.

Here is my hard drive configuration (view in monotype font for better readability)

Additional information:
Disk 1 (30gb) is connected to the Primary IDE controller and set to Master
Disk 2 (45gb) is connected to the Primary IDE controller and set to Slave
Disk 3 (200gb) is connected to a separate PCI controller (Promise Ultra100 TX2).  Disk3 is the only device on this controller and is configured as "Single"

Windows XP is installed on Disk3.
Disk 1 has a FAT32 partition for holding Linux setup CD images, and Disk1 holds the Linux installation itself.

When I setup Linux, I had it install GRUB to the MBR of disk1.  I reconfigured the system BIOS to boot from disk1 instead of disk3.  Thus, when the computer boots, I'm presented with the GRUB menu from which I can choose which OS to boot.  Unfortunately, if I choose "Windows" it does not boot.  It spits out:

"Booting Windows
rootnoverify (hd0, 4)
chainloader +1"

and then sits there.

Linux boots fine from this menu.

I am still able to get into Windows by changing the BIOS setting to boot from disk3 instead of disk1.  This is cumbersome, and is what this question is about:
How do I reconfigure GRUB so that it boots windows properly on this system?

Here is the /boot/grub/grub.conf file:

==============
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,1)
#          kernel /vmlinuz-version ro root=/dev/hda3
#          initrd /initrd-version.img
#boot=/dev/hda
default=2
timeout=10
splashimage=(hd0,1)/grub/splash.xpm.gz
title Linux (2.4.20-8smp)
      root (hd0,1)
      kernel /vmlinuz-2.4.20-8smp ro root=LABEL=/ hdd=ide-scsi
      initrd /initrd-2.4.20-8smp.img
title Linux-up (2.4.20-8)
      root (hd0,1)
      kernel /vmlinuz-2.4.20-8 ro root=LABEL=/ hdd=ide-scsi
      initrd /initrd-2.4.20-8.img
title Windows
      rootnoverify (hd0,4)
      chainloader +1
==============

I am confident the problem lies with the line: "rootnoverify (hd0,4)" but I am unsure what values to put in there.  So, how do I tweak the above grub.conf file so that I can boot Windows XP and Linux?
