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 just acquired, - at ENORMOUS expense (sic) an OCZ 520 ADJ power supply and an ASUS A7S8X-MX motherboard, and have deployed them in an old Dell 486 box chassis with a new 20 GB EIDE disk. ($10.00!)
If I test the power supply with a paperclip on the green lead etc, it comes up fine, but if I plug it into the motherboard along with a chassis fan
then all that happens when I switch on is the green LED comes on and I start getting network activity. (Guess its trying to boot from the lan).
Anybody got any ideas as to why it might not like the board, - Its a 500 watt+ model so would have thought it would be ok. Am I missing some vital signal going back to the power unit to tell it all is well?
Curious as to the significance of strapping the
green lead low, - this seems to be what it needs 'cos
it starts fine after that.
This is the same thing as pushing the power button. Does the 486 case have a momentary switch that plugs into the motherboard and is it connected to the correct header? Have you verified the case switch operates correctly?
The green LED is the 5V DC standby power that is also used to provide voltage to the ethernet adapter for Wake On Lan , power on timer functions etc.
Dur, - This has probably moved me forward considerably,
- albeit at the cost of some embarrassment! There is no
power switch on the box I'm using because it was hard
wired to the motherboard I've removed and now given
away. I thought the mains switch on the back of the
power supply would suffice, but from what you say it
seems I need to connect an on/off switch to the appropriate
pins on the new motherboard also.
I wonder whether I could simply short them out with a jumper?
I have found over the years that electrical equipment often
does work more successfully when switched on than otherwise.
Yes. The switch on the PSU itself is a master switch i.e. the unit is completely shut off including the standby power but it isn't used to actually turn on the computer.
Yes you could just use jumpers. In reality that is what the push button power switch does. Just make sure the 5VDC wire does not flap around which might cause damage if it randomly touches the motherboard.
