Booting wrong kernel

I have been using grub on a remote linux (redhat) server. After a yum update
now I always boot a kernel which is old. If I modify the grub.conf and
change the default it STILL boots the same kernel ignoring the entry I asked
for. I noticed lilo is installed. Could it be I got switched to lilo during
my yum update ? Is there a way to tell remotely which boot manager I am
using? Thanks

Why not just install or re-install grub eg with

grub-install --recheck /dev/hda

Then you will know you are using grub.

A switch to Lilo is almost assured _not_ the case. Would require that
Lilo be written to MBR(?) and that Lilo be run from Linux, rebooted,
etc.

Are you sure that the "update" did not _replace_ your old kernel?

What does
$ ls -l /boot
and
$ ls -l /boot/grub
show?

As root, what does your /boot/grub/grub.conf show? Your
/boot/grub/device.map?

When you change grub.conf, do you change the default ;)?
default=???

Since you can re-boot the machine are you able to run grub without the
menu, ie., are you physically present at the machine's console? If so,
can you get grub to load your old kernel "manually"? If not, see above
;)
