You can select the correct kernel at startup when the appropriate screen is displayed (ie a list of kernels), and I think that selection remains permanently changed. It's only on for a few seconds so be quick.
Otherwise login as root & do
pico -w /boot/grub/grub.conf
CAREFULLY make any necessary changes eg assuming the first listed kernel is what you want then change the line to read.
default=0
Ctrl o (to save)
Ctrl x (to exit)
then reboot.
Never mind, I got impatient and decided to try this again. It worked. default=2 was the state when I found it and I changed it to 0. all is fine now.

So why does this or how does this mix up happen? Am I the only one effected by it or are other SME users too? Is there something I can do differently to make sure this mixup doesn't happen again?
