FAQ: Fooling pc to think a keyboard is plugged in.

kevinlekiller · 11-01-2005, 11:52 AM

I was helping ooopseyesharted , and I told him that if you have no keyboard the computer might give an error. Anyways lets gon on with the tut. :

Theres 2 ways to get the computer to boot.

1) The soft method (might not always work).

2) The hard method (always works).

-----------------------------------------------------

1) The soft method: (soft = software)

a) Go in your computer bios settings.

*(on most computers: press delete when you first boot the computer)
**(On computers such as dell , compaq , hp , etc... , its usualy one of the F keys).

b) Look for: "halt on keyboard error" Or something similar. - Set it to False ( or no).

If you have this option : "halt on all errors" or something similar - Set it to False (or no.)

If you have none of these options move to the hard method

..c) On some computers enabling Quick boot in the bios menu will bypass the keyboard check.
-----------------------------------------------------

2) The hard method (hard = hardware)

For this mod you need a 10k ohm resistor (carbon film). (you can get them at radio shack).

AT style connector(older):

There are 3 ways you can do this:

1. get a old keyboard and cut the AT plug.

Strip the wires , with a tester check wich pins go with wich wires. We need the wires for pin 4 and 5(check the picture above).

Solder the resistor between the 2 wires you found.(solder the resistor in any direction it doesnt matter).

2. Insert the resistor on the motherboard connector between pins 4 and 5 and hot glue it in place.

Or 3. With a tester find were pins 4 and 5 lead on the motherboard. And solder the resistor there.

...........................................

Ps2 style connector (newer):

1. get a ps2 keyboard and cut the ps2 plug.

Strip the wires , with a tester check wich pins go with wich wires. We need the wires for pin 3 and 4(check the picture above).

Solder the resistor between the 2 wires you found.(solder the resistor in any direction it doesnt matter).

2. Insert the resistor on the motherboard connector between pins 3 and 4 and hot glue it in place.

Or 3. With a tester find were pins 3 and 4 lead on the motherboard. And solder the resistor there.

Thanks for the FAQ, Kevin. Added to the FAQ to the FAQ's.

Or better yet if you going to waste a KB just open it and extract the PCB (brain) and forget about the buttons, housing etc, connect it like a regular KB (hide the brain somewhere in the car)

BTW finally I see that the monkey (kev) is giving back to the community. J/k

Thanatos.

what about just bending the resistor into a U-shape and inserting it into the required pin receptacles on the motherboard and hot-glue-ing/taping it into place so it won't fall out?

then there's no need to waste a perfectly good keyboard.

EDITEd-------------

I miss read my own post , but its already there , its just I didnt write it well. Let me write it back.

Thanks.

Well that idea is better than solder something to the mobo, but like here in miami KB are $3.00

Thanatos.

Resistor - 5 cents.

Hotglue gun + hot glue 1 $

Installing it all - Priceless

hi,

can you please give me more detail, like step by step if you have a picture, it wil be awesome, sorry I am kinda noob. I'd like to do the hard method, since my computer doesn't has "halt on keyboard error" or something similar.

Can you tell me, what kind of stuff I need, and how I am gonna to do it, thanks for helping.

Call me crazy, but it would appear that the instructions clearly state what is required

There were even pictures!

No offense, but if you're having trouble following these instructions, maybe you need to look into a different hobby.

You dont need a keyboard, you can buy an extension , or use a broken keyboard that dont work in a pc no more.

And the reason why you would use just the cable and not the whole keyboard(pcb) is to save space.

shinjetko · 05-21-2006, 01:09 AM

Hi guys,

thank you for helping, I just want to make sure, what I do is right.

So, all I need is a connector (Ps2 style connector (newer)), then I need to use 10k resistor, to soldier between the wire of pin 3 and pin 4 for the keyboard connector right ? After that just plug in the other side of the keyboard on motherboard right ? thank you.

Bugbyte · 05-21-2006, 12:43 PM

Umm, right. But if you have to ask the same question three times to make sure that you have figured out how to bridge two wires with a resistor, I'd recommend that you not only don't do it, but seriously reconsider whether you're equipped to install a PC in your car.

There are lots more difficult and fuzzy things about installing a car PC than this three step, very clear tutorial.
