Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

and found that the results of its output are different to mine, for example they say suggest using swapon -s to identify the swap, and then that fdisk -l should get:
fdisk -l /dev/hdb
Device Boot Start End Blocks Id System
/dev/hdb1 2328 2434 859446 82 Linux swap / Solaris
Replace /dev/hdb with the device of the hard disk on your system with the swap partition on it. You should see output that looks like this:
but on my system I get this:
# swapon -s
Filename Type Size Used Priority
/dev/mapper/VolGroup00-LogVol01 partition 2031608 0 -1
# fdisk -l /dev/mapper/VolGroup00-LogVol01
Disk /dev/mapper/VolGroup00-LogVol01: 2080 MB, 2080374784 bytes
255 heads, 63 sectors/track, 252 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/mapper/VolGroup00-LogVol01 doesn't contain a valid partition table
so does this mean that I'm not presently correctly set up?
do I thus need to do the following on my partition:
run fdisk and using the 't' menu option
btw, my existing single disk is partitioned as:
