HP Trap Alerts

[Paul Crittenden]

I finally got around to looking at this again. Here is part of my
grub.conf.

default=1
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Red Hat Enterprise Linux AS (2.6.9-34.0.2.EL)
        root (hd0,0)
        kernel /vmlinuz-2.6.9-34.0.2.EL ro root=/dev/VolGroup00/LogVol00
rhgb q
        initrd /initrd-2.6.9-34.0.2.EL.img
title Red Hat Enterprise Linux AS (2.6.9-34.0.2.ELsmp)
        root (hd0,0)
        kernel /vmlinuz-2.6.9-34.0.2.ELsmp ro
root=/dev/VolGroup00/LogVol00 rhg
        initrd /initrd-2.6.9-34.0.2.ELsmp.img
title Red Hat Enterprise Linux AS (2.6.9-34.EL)
        root (hd0,0)
        kernel /vmlinuz-2.6.9-34.EL ro root=/dev/VolGroup00/LogVol00
rhgb quiet
        initrd /initrd-2.6.9-34.EL.img
title Red Hat Enterprise Linux AS (2.6.9-34.ELsmp)
        root (hd0,0)
        kernel /vmlinuz-2.6.9-34.ELsmp ro root=/dev/VolGroup00/LogVol00
rhgb qu
        initrd /initrd-2.6.9-34.ELsmp.img

As you can see the default is 1 and hiddenmenu is turned on. Would the
next oldest kernel be 2 or 3? Line 2 is the ELsmp but line 3 looks like
the next oldest kernel.

Hi Paul,

Going back to an older kernel sounds good

In principle, the GRUB boot menu should allow you to choose the kernel. 
Immediately after
the BIOS has handed control over to the boot loader, you have a couple 
of seconds to
hit a button, then you can select an earlier kernel manually.

For permanent selection, edit "/boot/grub/grub.conf" and edit the 
"default" index value to your
desired kernel as described here:
