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 have this SL 5.5 installed. But every time I try to shut down, it stops with 'acpi-power-off called'. I searched how to solve such problem, and is suggested to change 'grub.conf' and add 'acpi=off'. Here is detailed info. of my 'grub.conf'. Anyone can tell me where to add this 'acpi=off'? Thank you so much!
# grub.conf generated by anaconda
# Note that you do not have to rerun grub after making changes to this file

I logged in as root, as I've got [Permission Denied] message when I tried to change 'grub.conf'.
Then change it according to your suggestion, it still did not work.
Did i change correctly?
Distribution: Slackware (mainly) and then a lot of others...
If you just want to try 'acpid=off' you can go into the grub menu (when you have the grub screen) and then press 'e' to edit. Go down to the line that says kernel and then at the end add 'acpid=off' and then press 'b' to boot. Check if the shutdown works properly there.
If it does not work then we would look at BIOS.
