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.

Not to sound like TOO much of a newbie, but can a hard drive and a CD drive share the same IDE cable with the proper Master/slave settings? If so, what are the proper settings and what jumper pin configuration does Dell use. I'm hoping the readers of this questions will be believers in the "there's no such thing as a stupid question" axiom.
Yes you can connect a harddrive and a cd-rom on the same IDE cable. Just set one master and one slave. As for on which pin to place the jumper.. That'll be on the sticker that's usually on the harddisk and cdrom..
Maybe you will feel better if I display my ignorance
Does this mean there is no real difference between the 2 cables? For example, if the cables for the hard drives and the cd/dvd drives were switched an OS would install as normal. And the hard drives would now be hdc and hdd?
I'll probably regret asking this. The coffee hasn't quite kicked in.
yes, there is no difference between the two cables. ide cables are interchangable, they are passive components (i.e. the cables dont actually do anything, they are literally just peices of wire stuck together). you can get two different types of ide cable, 40's and 80's, the difference is in the number of wires in them, but dont worry too much about that, they are interchangable too, you can use whatever you have to hand.
you can swap cables at will, and it wont change drive assignments, thats handled on the motherboad and the drives. drkstr had it right with his list. most mobo's have their ide plugs labelled IDE0 and IDE1 (some label them IDE1 and IDE2), the IDE0 is the primary ide chain, then IDE1 is the secondary ide chain. it doesnt matter what cable you use, if you have a hard drive set to Master and plugged into IDE0, it will always be the primary master and appear in /dev/hda, and so on. in general, cables have no effect on the assignment of drives or devices, they are just there to connect two things together.
We appear to have some IDE cabling experts in this thread. Would someone correct or confirm my understandings on this IDE stuff? (p.s. - this isn't a thread hijack - I think the answers are relevant to the OP's original question )
(1) Cable Select will only work on 80 wire cables. With a 40 wire cable you will have to select your own Master and Slave manually. True or False? (I think True)
(2) Mixing devices of different speeds (e.g., a harddisk and a CD-ROM) on the same cable will slow the faster device down. (Again, I think True - but I'm probably wrong.)
I've avoided the need for an answer on my personal systems by using 80 wire cables with CS and manually setting M/S with 40 wire, and only putting similar devices on the same IDE cable. I'm now wondering if this is really necessary.
If you Google on cable select, you'll find a couple of sites which explain what cable select actually is, and how to quite simply modify a 40 cable to make it work (80 cables aren't univerally available, apparently.) Interesting stuff.
