Choosing Linux Kernel

Hi All
I recently upgraded my Mandrake 9.1 box to Mandrake 10.0 and the 2.6 kernel. However when I execute uname -a I still get a 2.4 kernel:

Linux hostname 2.4.21-0.13mdk #1 Fri Mar 14 15:08:06 EST 2003 i686 unknown unknown GNU/Linux

I assume this means I am still booting into a 2.4 kernel? In my /boot directory I have the following:

There appears to be a 2.6 kernel in this directory - so how do I tell Linux to boot from it, and is that a wise thing to do?

Do I change the symbolic link 'config' to point at the 2.6 config file?

Thanks for any help!

systemd-volatile-root.service

SYSTEMD-VOLATILE-ROOT.SERVICE(8)			   systemd-volatile-root.service			  SYSTEMD-VOLATILE-ROOT.SERVICE(8)

NAME

       systemd-volatile-root.service, systemd-volatile-root - Make the root file system volatile

SYNOPSIS

       systemd-volatile-root.service

       /lib/systemd/systemd-volatile-root

DESCRIPTION

       systemd-volatile-root.service is a service that replaces the root directory with a volatile memory file system ("tmpfs"), mounting the
       original (non-volatile) /usr inside it read-only. This way, vendor data from /usr is available as usual, but all configuration data in
       /etc, all state data in /var and all other resources stored directly under the root directory are reset on boot and lost at shutdown,
       enabling fully stateless systems.

       This service is only enabled if full volatile mode is selected, for example by specifying "systemd.volatile=yes" on the kernel command
       line. This service runs only in the initial RAM disk ("initrd"), before the system transitions to the host's root directory. Note that this
       service is not used if "systemd.volatile=state" is used, as in that mode the root directory is non-volatile.
