installing WinXP as dual boot: how to see installation CD?

[Derek Lee]

Hi,

I am stuck on a problem using GRUB (v0.92). I have only played with GRUB 
configuration in trivial ways before, so this is a bit of newbie question...

I have a RedHat 8.0 system and would like to install XP on a partition 
of my first hard disk. I cannot use the XP installation CD directly 
because that would overwrite the first partition of my disk which 
contains the Linux /boot partition. (But my BIOS can indeed boot from CD.)

So, I have learnt to use the map function, and I am proposing to do the 
following in grub.conf for the installation of XP:

title Windows bootable CD
        map (hd0,0) (hd0,8)
        map (hd0,8) (hd0,0)
        chainloader (hd1)+1

Problem: I cannot persuade GRUB to find the bootable CD which sits in 
/dev/hdc

In fact, GRUB only recognises fd0 and hd0 at the moment.
I tried adding /dev/hdc as (hd1) in /boot/grub/device.map but that did 
not help. (Do I have to do grub-install before I reboot the system? How 
do I get GRUB to read that file on booting...?)

My /dev/hdc is an IDE CDROM drive. It lives on a different channel from 
/dev/hda which is my hard disk.

Does it help if I try to address the CDROM drive using BIOS numbers?
Can one deduce it from the info below?

Any help would be much appreciated!
