Right, of course.
Here's /boot/grub/grub.conf on sda1:
# grub.conf generated by anaconda
.........................
#boot=/dev/sda
default=saved
# default=0
fallback 0 1
timeout=5
title Fedora (2.6.27.25-78.2.56.fc9.i686)
root (hd0,0)
kernel /vmlinuz-2.6.27.25-78.2.56.fc9.i686 ro root=/dev/VolGroup00/LogVol00
initrd /initrd-2.6.27.25-78.2.56.fc9.i686.img
savedefault
title Fedora (2.6.27.24-78.2.53.fc9.i686)
root (hd0,0)
kernel /vmlinuz-2.6.27.24-78.2.53.fc9.i686 ro root=/dev/VolGroup00/LogVol00
initrd /initrd-2.6.27.24-78.2.53.fc9.i686.img
title Fedora 12 (2.6.31.5-127.fc12.i686.PAE)
root (hd1,0)
kernel /vmlinuz-2.6.31.5-127.fc12.i686.PAE ro
root=/dev/mapper/vg_server-lv_root LANG=en_US.UTF-8
SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=us
initrd /initramfs-2.6.31.5-127.fc12.i686.PAE.img
savedefault 0
And grub does find the kernel and initrd on (hd1,0)
grub> find /vmlinuz-2.6.31.5-127.fc12.i686.PAE
find /vmlinuz-2.6.31.5-127.fc12.i686.PAE
(hd1,0)
grub> find /initramfs-2.6.31.5-127.fc12.i686.PAE.img
find /initramfs-2.6.31.5-127.fc12.i686.PAE.img
(hd1,0)
So I'm beginning to think my problem is that grub just doesn't boot F12.
As I said this is a remote server. And I want to make sure it's running
_something_.
I've set up grub.conf with fallback and savedefault, as you can see. I
then run "savedefault --default=2 --once" from the grub command line,
and reboot.
Any thoughts? I'll start a new thread with better subject line.
Thanks,
sean
