A single drive has been partitioned to accommodate
both systems. The
RH8 install was the first installation, and in the process of installing
RH9 grub was rewritten for it (and not for the RH8 partition). So, how
do I indicate the choices ? Here's what I'm thinking about for an edited
grub.conf :
default=0
timeout=10
splashimage=(hd0,4)/grub/splash.xpm.gz
### RH9
title Red Hat Linux (2.4.26-1.ll.rh90.ccrma)
root (hd0,4)
kernel /vmlinuz-2.4.26-1.ll.rh90.ccrma ro root=LABEL=/1 hdc=ide-scsi
initrd /initrd-2.4.26-1.ll.rh90.ccrma.img
### RH8
title Red Hat Linux (2.4.19-1.ll)
root (hd0,0)
kernel /vmlinuz-2.4.19-1.ll ro root=LABEL=/ hdc=ide-scsi
initrd /initrd-2.4.19-1.ll.img
Is this kosher ?
It looks good to me given the partition map. But I'm not a grub expert
either...
What will happen if it's incorrect,
As long as you have not touched the rh9 boot line the worst, I guess, is
that you won't be able to boot into 8.0.
and what should I
do if grub fails ? How do I specify that I want RH8 to be the default
system ?
If you get to the point of being able to boot 8 then changing the line:
default=0
to
default=1
should do the trick and the system should boot into 8 after the grub
timeout...
I guess you are editing the grub.conf that is in the /boot partition for
redhat 9, right? (/boot/grub/grub.conf, the last /boot partition
installed).
