Installation instructions:

Upgrade the packages as root:
# upgradepkg kernel-*.txz

On Slackware 14.0 systems the kernel version has changed, so you will need
to rebuild your initrd if you are using one.

For Slackware 64-14.0 use this command:
/usr/share/mkinitrd/mkinitrd_command_generator.sh -k 3.2.45 | bash

For Slackware 14.0 (32-bit) SMP, use this command:
/usr/share/mkinitrd/mkinitrd_command_generator.sh -k 3.2.45-smp | bash

For Slackware 14.0 (32-bit) uniprocessor, use this command:
/usr/share/mkinitrd/mkinitrd_command_generator.sh -k 3.2.45 | bash

Please note that "uniprocessor" has to do with the kernel you are running,
not with the CPU. Most systems should run the SMP kernel if they can
regardless of the number of cores the CPU has. If you aren't sure which
kernel you are running, run "uname -a". If you see SMP there, you are
running the SMP kernel and should use the 3.2.45-smp version when running
mkinitrd_command_generator. Note that this is only for 32-bit -- 64-bit
systems should always use 3.2.45 as the version.

For all systems (13.37 and 14.0):

If needed, edit your /etc/lilo.conf to adjust the version number on the
"image =" line. By default this will not have a version number and will
just follow the /boot/vmlinuz symlink, but you might need to make this
change if you've edited your lilo.conf manually.

Then, run "lilo" to reinstall the boot loader.

If there are no errors from LILO, reboot the system to begin using the
new kernel.
