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'm looking to find out if I can add a second processor to my Red Hat 9 system. I am currently running one hyperthreading Xeon processor. The kernel sees this as two processors and has installed with SMP support, so I currently see 2 processors. I want to know if I can add another identical processor to the machine without recompiling or anything.
I guess the question is .....If I already have the SMP kernel can I just pop in additional processors without having to reconfigure things.
BTW this is a Samba(latest stable release) server with Red Hat version 9 using our windows 2000 active directory user accounts via winbindd if any of that matters.
Thank you for your responses, I appreciate the help. The grep command returned CONFIG_NR_CPUS=8. Soooo I guess when you install redhat in a dual processor enviroment, The default must be eight. I assume I should be good to go on my second processer addition as it will show up as 4 total. ( Two dual hyperthreaded ) I guess I will find out for sure. I'll just pop it in there and see what happens.
No think nothing of it, I just figured I would use a distro that I though would have the most possible support and some kind of company to link to it. It just seems that when drivers are released for linux there is always one for redhat specificly. I am a little bit of a newbie, but I have gotten this server to the point at which it is using dual nics (bonded) and the usernames from my Win 2k domain, printing pdf's etc..... I have lost a few handfuls of hair over it, but for the most part I haven't hit any really impossible roadblocks. I have tried Mandrake, Knoppix, Caldera and they seem to be very similar as far as configuring things...but for the most part I have been happy with RedHat's stuff. I know that many linux guys look at redhat like they are the next microsoft. I am willing to run other distro's though once I get the hang of this.
