problem with grub in redhat 9 (dual boot win98) - Linux Setup, Configuration & Administration

[Alex]

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!

While most peoples' opinions change, the conviction of their
correctness never does.

Assuming your slave drive has only one partition...

Try the syntax (as modified above). This chainloads to the partition's
BPB loader code (not the MBR on the slave drive.)

Yes, I think it does. 

I've tried your amendment and I get the same result - grub comes up in
command line mode, no menu.

thanks,

Problem now solved... the problem is detailed here:
http://mail.gnu.org/archive/html/bug-grub/2002-03/msg00093.html

basically, booting 98 causes (hd0,0) partition to be set to partition
type 0x93, I have set it back now with a parttype command in menu.lst.

thanks all who answered,
alex

Uh? I posted that! D'oh... where the hell is it?
<remembers> oh, mailserver was down, I did File -> Save and then
couldn't find where it had gone, then forgot that it hadn't been posted...
