Hi lost my CMOS jumper cab
what do???
where to get that little jumper cab
or can i just short it and let it like that
I APPRECIATE ANY HELP

redeemer · Apr 16, 2013

Short it! Or go to your local computer/electronic store for a replacement!

mcnumpty23 · Apr 16, 2013

or if you have an old ide dvd drive or hard drive lying about take the jumper off that

Yes, I've bridged the gap with a screwdriver without issues before. Do at your own risk though.

Alternatively, if you or someone you know has any old HDDs or cdrom drives lying around, grab one from the back of one of them.

Or as redeemer said, most places will just give you one for free if you ask them.

Ok
my motherboard is sabertooth z77 cmos jumper have 3 pins not 2
so i think i have to short 2 of them in a side right?
and i dont know where were the original
thanks to replay, hope u undrestand my english

i have a lot of cdroms, lol is there any jumpers cab in it?

mcnumpty23 · Apr 16, 2013

if they are ide cd roms then there should be one jumper on the back of them

and yes you only short 2 pins

the jumper should be on pins 1 and 2

Khalan · Apr 16, 2013

You need to bridge the 2nd and 3rd pins with the power cord unplugged for about 5-10 seconds.

To clarify, normal behaviour is for pins 1 and 2 to be bridged with the jumper. Bridging pins 2 and 3 will reset the BIOS.

how to know 1 and 2? in which side? do i start in left or right side sorry if this a stupid question :XD

mcnumpty23 · Apr 16, 2013

1 and 2 should be starting from the left side

Khalan · Apr 16, 2013

Left (1) and middle (2) is normal, middle (2) and right (3) to reset.

CSS:

Normal:
 -------
[1]  [2]  [3]


Reset:
      -------
[1]  [2]  [3]

and once the jumpers on you dont need to touch it ever again

there is a clear cmos button on the rear of the motherboard next to the usb ports

taman1 · Apr 16, 2013

so do i need to short 1 and 2 and let it to be shorted right? because u know i lost the jumper cab
Thanks

mcnumpty23 :

That button is actually for their usb bios update function. Flashing the bios will of course also reset it but can be risky. Unfortunately it doesn't look like the Sabretooth has a bios reset button.

From Asus troubleshooting:
1.) Turn OFF the computer and unplug the power cord.
2.) Move the jumper cap from pins 1-2 ( default ) to pins 2-3. Keep the cap on pins 2-3 for about 5-10 seconds, then move the cap back to pins 1-2.
3.) Plug in the power cord and turn ON the computer.
4.) Hold down the < Del > key during the boot process and enter BIOS setup to re-enter data.

Khalan :

says on their website it has a clear cmos switch on the rear io

unless i am looking at the wrong motherboard

yes that button in back is for flashing the bios and dunno what other things can do, simply i dont care about that for now, i just bought that piece of carp and accidently removed the jumper cab whay did i do that? I DONT KNOW.
Thanks alot guys i greatly appreciatethat

Khalan · Apr 16, 2013

That's where I'm looking too - however I believe they're stating IF there is a reset button do this etc.
A search for sabretooth z77 cmos gives quotes like the following:

Oddly on a "overclocking oriented" motherboard ASUS didn't give any CMOS clear buttons anywhere and even more they are using jumpers.

Apparently there is no 'clear cmos' switch or button

the clear CMOS is a jumper instead of a button

Have a look here for the function of that button (halfway down the page, USB BIOS Flashback):

taman1 :

If you just need normal behaviour (keeping pins 1 and 2 bridged) without a jumper, you can try powering off and unplugging the pc, and sticking a small piece of foil over pins 1 and 2, making sure nothing else is touching the piece of foil.
IE. cut a tiny piece of foil, and push it down so that the left and middle pins pierce the foil.
Do at your own risk though, and it may not work (though it has worked for me with some electronics instead of soldering), but you're best off trying to get another jumper instead. Just ask at any computer or electronics retailer service desk and they should give you one for free, unless you can find one on the back of a spare HDD or CDROM.

Thank you dude, i already sticked a small foil over 1\2 pin and now it worked perfectly
and again, thanks alot ^^
