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!
