problem with grub in redhat 9 (dual boot win98)

I've just installed redhat9 to make a dual booting system (with win98)
and am having problems with grub.
(Note: my friend is sick of windows 98 virus++ and I am weaning her onto
linux so I really want to get this working for her!)

The setup: I had an existing windows 98 system, that had one hard disk
(master on ide0). I added another disk to the system, putting the new
disk as master on ide0, and the win98 disk as the slave on ide0. Then I
installed redhat 9 (shrike) from the three CD set.

The problem: well, setup went fine, I rebooted, and sure enough, grub
comes up, offering windows 98 or RedHat Linux. Selecting RedHat worked
fine, but selecting Windows 98 caused grub to hang and not boot windows
98. I searched on the internet for problems like this, and found a post
of someone advising you map hd0 to hd1 and vice versa to fix the problem
in this situation. So, I edited the windows98 section of my grub.conf to
be as follows:

title Windows 98
  map (hd0) (hd1)
  map (hd1) (hd0)
  rootnoverify (hd1)
  chainloader +1

..which appears to be the way to do it. (I didn't edit the RedHat
section, I left it as is).
Now when I boot up, grub drops through to the grub command line, without
showing a menu, which I believe is what happens when the config is wrong
or erroneous. Can anyone advise if indeed this means my grub.conf is
bogus, and how to fix it?
(Funnily enough, if I type the windows98 rules at the grub command line
as they appear above, and then type 'boot', windows 98 boots just fine!)

My full grub.conf reads as follows:

#boot=/dev/hda
default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Red Hat Linux (2.40.20-8)
        root (hd0,0)
        kernel /vmlinuz-2.4.20-8 ro root=LABEL=/ hdd=ide-scsi
        initrd /initrd-2.4.20-8.img
title Windows 98
        map (hd0) (hd1)
        map (hd1) (hd0)
        rootnoverify (hd1)
        chainloader +1

all help greatly appreciated!
