Well, when I say "reset" I dont mean it will reflash the bios back to what it was...hehe..I mean it will more or less return the BIOS to all the default settings. But sometimes that will help you to boot up...then you can get into the bios and check out the settings to see whats up.
The jumper is almost always right beside the cmos battery on the board.
And yes, if you have a manual it will almost always tell you where the cmos reset jumper is.
Usually there is a little jumper and 3 pins. When you find it, the jumper will be sitting on two of the pins....thus "shorting" or "closing" or "connecting" those two pins.
That it the normal place for the jumper to be set at.
But to reset the bios. you move the jumper to the other pin.
Picture 3 pins in a row....pins 1,2,3. Now, say the jumper on pins 1 and 2 is normal. So to reset the bios you take the jumper off of 1 and 2 and you put it on 2 and 3.
Let it sit a minute or so (for good luck) then put it back on pins 1 and 2 again and try to boot up.
I suppose it is best to have the computer unplugged while doing this.
If you take a flashlight and look at the motherboard..you will find the battery (looks like a nickel laying flat) and the jumper will be near it. You will usually see some small writing next to the jumper telling what to do to set it to "clear" or "reset".
Sometimes just taking the battery out for 30 minutes with the comp unplugged will do the same trick....but the jumper is there for a reason and its less hassle.
Here's a picture of a battery and jumper. If you look closely you see the other pin next to the jumper....so to reset it you merely move the jumper over one pin to short that extra pin and the center pin together. 30 seconds or a minute..then put it back like it was.

And here is a typical motherboard manual showing the layout....you see the battery and beside it happen to be several jumpers...so you look at the chart and it tells you which is the battery jumper....then you see it tells you which pins to put the jumper on etc. pins 1-2= default or "normal" and 2-3 = clear cmos.
