Making a BIOS reset switch

 

Time -- 30 min

Once you get yourself into over clocking and tweaking out your computers, your going to find yourself resetting the BIOS more than a few times. Like me, I enjoy pushing my system to the max - however push it too far and I'll be opening my case and searching for this little tiny jumper usually buried under my sound card.

Well NO MORE!

With this little easy to do tip, you can just turn off your computer and flip a switch - then back again. The BIOS will be reset in seconds ~ all on the outside of the case. Some motherboards offer a special key to hold down on the keyboard to reset the BIOS, however this only seems to work on PS/2 keyboards. So with this mod, whether you use a USB keyboard or your mobo doesn't support this feature - this should help.

 

All parts we will need:

-An On/Off switch with three leads
-One set of Led's that are paired together
-One Led by itself

-Solder (optional)
-Electrical tape

 

First of all you need to find a switch with three (3) connections on it. Most motherboards have a 3-pin connection on them to reset the BIOS. You just move the jumper over one pin and back again - while the middle jumper is always connected and boom, it's reset.

I had this switch laying around. It's already on a PCI rail, but wouldn't really matter. You can mount this where ever you see fit.


The next step was to find a set of Led's that were wired close together. I grabbed this reset Led from my stash.

Strip down the ends with your wire strippers. Now we need a third Led to make this process work. I used an old internal speaker for the job. Yes, there is now purpose to have one of these laying around.

We only need one of these wires so cut the plastic off in the middle of the wires.

Careful not to cut the wires - just slowly cut the plastic.

At this point go ahead and solder the wires to the switch. It doesn't matter which wires go to the three connectors. However it will matter when it's time to put all three Led's together - you just need to worry about the middle connection on the switch going to the middle Led.

So here is after I soldered.

Now find the middle wire and the middle Led.

Grab the Led that was cut all by itself and glue/bond this to the outside of this.

Once secured I also used electrical tape to secure it further. Also use electrical tape on the solder points as well.

Ready to be installed. I had to remove my sound card to get to my BIOS jumper - and it's so tiny to get a hold of.

 

Now, one side will be "off" and one will be "on". If you know your switch, then you know which way to place this on the motherboard. What I did was turn off my PC, make the connection to the mother board and try to turn on the PC. The PC did not turn on, so I flipped the switch and turned it back on.. of course my BIOS was reset but I'm just fine with that. But if your not fine with that, make sure your know your switch.

Once secured, I'd recommend looming or wrapping up the wires so it's "pretty". Do as I say.. not as I do.

 

Here is the switch from the outside.

 

Now, once I tweak a little too hard and need to reset the BIOS, I don't need to open the side of the case... I love it.

Update: A friendly viewer by the name of Hani just mentioned he did the same thing only he used a CD-ROM audio cable. This makes since due to the fact it is already equipped with three cables.
