How to Properly Clear CMOS...

Hey Guys,
I’ve checked the MSI manual and I’ve taken a look at the sticky/FAQ’s over here in the forum as well, and I wasn’t really able to find instructions on how to properly clear the CMOS (after a BIOS flash).
So first of all what’s the correct way to clear the CMOS?
1. Should I leave the power cord connected to the PSU and then press the “clear CMOS button” while the battery is still in the motherboard?
2. OR should the power cord be detached from the PSU and the motherboard battery removed and then should I press the “clear CMOS button”? (And if so, for how long should the batter be removed before connecting it back to the motherboard?)
Secondly,
I was looking over the steps in this guide (http://www.msi.com.tw/html/support/bios/note/ntfs.htm) and I’m not sure at which point I should clear the CMOS. After I’ve executed the flash command and the flash has been complete, it says in step 12. “Reboot your system when prompted.”
So should I turn off the machine right after the BIOS flash and then clear the CMOS… or should I reboot the machine right after the flash and then clear CMOS ?
Any help would be greatly appreciated as I really don’t want to FUBAR my board.
Thanks in advance.

1. When I enter the flash command in DOS and the flash program completes the flash... will it say something like "flash successful" OR the only way I’ll know if the flash was successful is if after the flash I reboot and the machine posts?
You will have a message like 'Hit F1 to reboot' in principle all is well...

2. I understood everything in the steps that you listed up until step 4. Should I press the orange "clear CMOS" button first (Now do I have to hold it down... press it a few times... or just press it once) and THEN remove the battery... OR should the battery stay in at all times?
While you press the button the battery must stay in it's place, it's is voltage that will clear the BIOS in a certain pin of the IC...
As for the time to press...could be 1..2..3 seconds, no time defined, as soon as you press the button the Bios is cleared...but give it 3 secs.
And it's not necessary to remove the battery at this point only in extreme cases.

Finally, is it actually beneficial to clear the CMOS after flashing the BIOS? From what I’ve read... One of the main reasons to clear the CMOS after flashing to a new BIOS is so that you get rid of all the old BIOS options/commands that might be still lying around. So I can only see this as a good precautionary step rather than doing any harm to the motherboard, or causing the risk there of.
It is highly beneficial to clear the Bios after an update, because some settings could be somewhat out of place and mess up your discs or memory or even the processor...one never knows...it is always better to clear for ensurance.
Be well....

How do you clear CMOS on a MSI K8N-SLI board?

I no longer have the manual and I need to clear the CMOS on my MSI K8N-SLI Board. Actually, my issue is that nothing comes up on my monitor screen. I was 95% certain that it was the video card which was an old MSI NX6600 256MD eLite nVidia vid card. I'm in China at the moment and I bought a "Colorful" 9500GT 512MB vid card to replace it, however it does work. It may work for up to 2 minutes, and then prior to finishing the initial boot up, it says that the computer is placed into safe mode due to overclock???? I've never overclocked before.... Am I suppose to clear the CMOS? There is a small button near the HDLED jumpers which I had pressed assuming it was the clear CMON switch since I couldn't recognize anything else being a CLEAR CMOS. Can someone help me out? I'm in dire need of your expertise!

Properly clear cmos to acces the bios

Hello, my overclocking failed with my z77a-gd65.
The mainboard boots but there's no signal to the monitor (vga, hdmi, dvid) plugged into the mainboard.
And the usb keyboards don't work. Except the old ps2 keyboard that just turn the leds at the boot for 0,5 secs... Tried to press f2 but nothing does. I had the same issue one year ago. I think the daily overclocking wasn't good. And, ghe cpu was not fried. This time I tried 5 ghz with 2v. One year ago it was 4,5ghz and 1,3v. My board has a dead bios 1 one year ago and it still unusable. Last year, I still couldn't use the second bios for s.o.s. , I had to send to rma. Because the board was faulty and was under warranty. Should I again send it to the rma ? Or there's still a way to get access back ?

5GHz and 2v holy cow? you sure you didn't damage the CPU or its built in GPU? have you tried with a dedicated card? or a different CPU?
My mainboard has a dead bios1, I have now only bios2 working.
But, when my mainboard were working, I still couldn't switch bios, because it didn't worked. And, even when I tried to clear the cmos, while the mainboard was running, this option didn't worked. Battery, button, jumper.
My mainboard was faulty when got delivered first time.
I had one year ago to send it to rma to unlock it. That's how the bios was dead, I also thought that my cpu died or even my ram.
I will have to buy an ASUS Z77 board soon, I hate msi.
That was a 185€ flagship board. No warranty (just 12 months)...
The only solution is now to clear the cmos by a way that someone knows, I remember that I tried to remove everything from the board, and then put everything back on it. Still nothing.
Now, I don't know what msi have done last year. Last year wasn't an overclocking fail because I let the board on 4.5ghz 1.3mv daily and one day it didn't boot. I got the same thing now. The board has at least the instructions to reset everything if it does not work. But it does nothing.

How to Reset BIOS/Clear CMOS of an HP Pavilion 500-111ea

Hello,
I was trying to change my computers boot logo because i dont like the HP one, and now when i try to enter my bios i get beeping, can anyone tell me how to reset the BIOS/Clear CMOS, this will be much apreciated. The computer still works fine, i just cant enter the BIOS or the UEFI Firmware Settings thing. When pressing F10 at boot up the computer beeps 8 times
My computer is a HP Pavilion 500-111ea
Regards,
Kieran
<I posted this in the wrong selection a few moments ago, i hope this is the right place this time.>

Hi,
Please explain in detail what changes you made in an attempt to change the boot logo.
HP did not post a clear CMOS procedure for your model PC. Review the below image. Unplug your PC, hold down the power button for 1 minute. Now open up your PC and move the jumper blocks over to the left per the image for 30 seconds and then move the jumper blocks back. Plug the PC back in and give it go. If you still get the eight (8) beeps then you could try a ROM image recovery.
Eight (8) beeps in an invalid ROM image. Review this HP posted article for trying a BIOS recovery.
You might try this HP tools software. Download the software to a different PC and create the USB 2 bootable tools flash drive. If you can get the flash drive to boot up then look for a firmware management selection. There is not any documentation available on how to use this function so you are on your own. HP Support might be able to assist you with a BIOS recovery and/or you might be faced with sending in your PC to an authorized HP repair facility to have the BIOS reflashed.

How can I clear the CMOS/BIOS Password on Satellite L10

HOW can i clear the CMOS/BIOS Password?

Hi
Sorry to said this, but its not possible to delete the BIOS password without a help from the Toshiba authorized service provider.
The special procedure is needed to delete such password.
Therefore you have only one way out. Contact the ASP in your country and ask for the BIOS deletion

How to clear cmos with jumper method MSI Z97 Gaming 9 AC

no have socket for jumper/clear cmos ?

Quote from: pegadroid on 13-August-14, 18:37:12
ok. thank you all. now I'm not confused, I think its socket to clear cmos lost
If you mean the jumper no it did not come with one, nothing was lost. Older MBs had 3 pins for JBAT1 and came with a jumper and it was stored plugged into pins 1-2 and to clear CMOS it was moved to clear pins 2-3 and then moved back to the store position pins 1-2.

How to properly back up the iPhone (I clearly did it wrong)

I backed up my iPhone, named it and then restored it to the factory settings. When I went back and right clicked on the phone to "restore from backup", the backup I had just made was not there. Only a backup from September. Now, I've lost everything since September, that was on my phone. I was wondering what I did wrong and how to properly back up the iPhone for future reference. Does it only save 2 backups? I just am not sure why it didn't save my most recent backup, and rather, saved one from September. Sad, I lost a lot of important texts, numbers, notes and pictures. Thanks for any help!

I followed the Clear CMOS Ram guidelines but I can't get into Setup!

hey folks, thanks loads for the guildlines in the stickies, I followed the one for removing the battery to clear the CMOS RAM, and when it gets to the point where I press F1 to continue or DELETE to enter SETUP, whichever I press it just takes me to a blank screen with a flashing cursor in the top left corner (i think its the _ symbol or the -), and when I reboot I have to repeat the process of the monitor won't come on properly. If I just press DELETE to go into SETUP before the error comes up it does the same thing but theres a thick blue line at the bottom of the screen too.
Any clues?

cheers

Hello, thanks all for your reply.
I did notice my card is 2x and technically the board is 4x/8x, I read up on the AGP thing and it seemed very likely that it would work anyway. Am I stupid for thinking that it would work? Why would there be a checksum error because of that though?
Anyway, in answer to the original question I needed to boot from CDROM so I could format and install Windows XP on my hard drive so I entered the setup and changed it to boot from the CDROM first, there was also a section I changed from Manual to Auto - I can't remember specifically what it was for, but they were exactly the same anyway, I think I left it on Auto as that always went for the most stable option and I really wanted to avoid any trouble (ugh!). Either way, like I say it didn't change any settings anyway so I don't see how it could be that.
So I posted on Driverheaven.net here: http://www.driverheaven.net/showthread.php?t=102308
They suggested I clear CMOS and thats where I am now!
Thanks for the replies, any more ideas?

Clear CMOS ?

hello,
i'm gonna boot my pc for the first time, but not everything is installed yet, the hard drive, floppy drive and CD-RW aren't installed yet... . But still this is a very important first boot, because this way you can check the CPU and memory and graphics card, if they are installed properly and have them excluded for future troubles. my question is:
shoul i clear the CMOS (using hte onboard jumper) before booting it for the first time ? just to be sure there won't be any unlogical settings...with the consequensce that it won't boot...so clearing CMOS should be the right thing to do, right ?
thx
greetz

Hi hypetraxx,
No harm doing so Go ahead and clear 1st before installing anything as this is just a play safe method, in case your mobo have not got it cleared, but situations like this are uniquely rare
I usually don't bother to clear it before installing anything... :P but hey... everything still gets installed and works out fine and rock stable... :D!!!
All the Best... :D!!!

Clear Cmos KT4V-l

thanks !
due to a bad monitor the pc won't boot anymore
i think it did a bad voltage to the main board
now i know it because with my other main board
i got the same situation but there i could clear the
cmos with the jumpers.....
thanks for your replies ! ! !
(sorry for the bad englsih......) )

ok i'll try it tomorrow evening !
but i had the same problem with another mb and there i could solve it by clearing the bios
i ones let me tell that you can do it by sorting someting
wrong at the battery that would give me bad cmos check
but i don't know anymore how since the jumper for clearing cmos doens't work anymore
i even going to try the proposal of wonkanoby
one to success ? ? . . .i hop so almost one month and the board worked 1 day

[Athlon64] Clear CMOS Jumper orientation ???

I have a new MSI RS480M/RS482M Motherboard and the clear CMOS pin orientation is a little confusing. With the video connectosr and other connectors at the rear you normally count left to right, top to bottom, but the jumper came on the pins on the right side which would be pins 2 & 3 and in that case means "Clear CMOS". Which means of course if I boot that way I'll damage the motherboard. Since the numbers are not printscreened I can't tell which pin is number 1 so I'm not sure how to jumper it for "Keep CMOS Data"? Any help appreciated.

Thanks for the reply Foxbat. Yep .... I understand that. I guess my question is: Which pin is number 1? If you are looking at the pins from the left side of the motherboard the pins would be vertical and top to bottem would be 1,2,3. However, if you are looking at the pins from a position that all the connectors are in the back (video, com, audio) then ... normally (going by all the old rules - left to right, top to bottem) #1 would be different, the pins would be horizontal and #1 would be on the left side and just the opposite. So it depends on how you position the motherboard when you look at it. Looking at pin #s that are printscreened (the ones that happen to be numbered) there is no consistent method of numbering .... and I cannot see any numbering on the CMOS pins. Thus my dilemma.

Clear CMOS - without moving jumper/pins

Thinking about trying to OC my 3000+(W)@Neo2.
My case and eq. in genreall makes it hard to clear CMOS the "old way", and I remember someone telling of a keystroke one could do under reboot to clear CMOS.
How can I do this on the Neo2 and what are the dissadvantages?

Syar2003
If "Ins" Key is held down when powering up , system starts with reduced fsb and other safe settings . Making that clear cmos jumper uneccesary when OC has gone bad.
Note ! It must be powered off and powered on with the key pressed (just restart key + "ins" wont work).
