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.

I assume you burned it as image onto the CD. Did you get anything at boot that indicated you're booting from CD or does it just ask you for a password before doing anything? Have you had the change to look at the jumper devnull10 referred to?
I haven't tried the jumpers yet (assuming since it's effectively the same thing as removing the battery-just powering it down- that it the jumper trick wouldn't work either)- And no, I didn't burn it as an image (I don't think ) Just extracted the downloaded image (.iso) and extracted it. This worked for the 2 dell servers I just installed OSs on and thought it would work the same here. I know the .iso files are supposed to be detected and are self-extracting but I haven't had much luck getting this to work thus far... If I'm going about this the wrong way please let me know...
Not saying your explicitly doing it the wrong way but I for example use CDBunerXP on my work laptop (to bad but it comes with Windows XP) and always use the option to Burn from image. Hasn't failed me yet. Have you tried the CD on other machines to see if it can be booted from?
The jumper works differently than the battery removal. The jumper actually discharges a capacitor on the motherboard to clear the CMOS information. Every system I've tried it on, removal of the battery has done the trick, but I have read that some motherboards also require the discharge of this capacitor. As long as it is still storing electricity, it maintains the current CMOS settings. The procedure is: the jumper will be across two of the three pins available (middle pin and one of the other end pins), move it to the middle pin and the other end pin; power up the machine and let it (try to) POST; turn off the machine and move the jumper back to its original position; power up again.
EDIT: This method is not available on all machines. The jumper board, if it is there, will be a small, 3-pin one, near the battery on the motherboard. If you don't see this set of jumper pins near the battery, chances are your machine doesn't support this method.
