Cmos Error

[JoeSoapy]

What does 'CMOS checksum error' mean. I had to press the F1 key
as required to get this computer started.
Motherboard is Gigabyte GA-K8V Ultra-939. One gig ram, AMD 64
CPU running WinXP Pro Sp2.
I am a bit scared to reboot in case it wont start again, I must
add I am a novice with computers.
Thx for any help given.

Sometimes it just happens for no reason, (not often)

Change the CMOS battery.

Thx I will change the battery.

If you change the battery, don't forget to short the pins near the battery.

 

[JoeSoapy]

Why would I want to do that??

You wouldn't. You don't need to.

I thought not, thank you for the reply.

Jumpering the pins sets the BIOS to default settings. If you boot without
jumpering the pins, you will get a CMOS checksum error unless you set the
the BIOS first to default settings anyhow. That is why the pins are there.
It is in your manual.

Removing the battery and installing a new one will do this. If it makes
you happy to move jumpers around and your motherboard supports it, by
all means do it. However, in all the years that I and other techs have
been changing out CMOS batteries, it has not been necessary. The error
you are seeing happens because you need to go into the BIOS and reset
the date, etc.

Hi I am starting to get confused here. Surely if I replace the
battery within seconds nothing will change. It was written that
the reason for the CMOS error was I need to replace the battery.
Why would I have to reset the BIOS???

Just replace your battery and don't worry about this. It really just
depends on your motherboard what will happen. If CMOS retains the
settings, fine. If it doesn't, fine. Just set the correct time and
date. Really, this is *not* something to make a big deal out of.

If you can get its manual, the procedure for replacing the battery is in
there. Most likely, you just replace the battery and restart. If you had any
custom settings in the BIOS, you can then reapply them. In almost all cases,
replacing the bettery resets the BIOS in seconds. No big deal.

You can always reset the BIOS later if necessary, but I bet a nickel it's
not.

I quote from the Abit procedure for flashing the BIOS:

8. Switch off the power supply unit or pull the power cord. There is a
CMOS jumper near the battery. Change the jumper position from default 1-2
to 2-3 for one minute to discharge the CMOS data, and then put it back to
default 1-2. Switch on the power supply unit or put in the power cord.
Press the power on button to boot up the system. If it works, hit the
"Del" key to enter the BIOS setup page to do correct settings.

Do it the right way. Do it the Abit way. Every motherboard manufacturer
provides the identical instructions for flashing the BIOS.

Forget about "most likely" and "In almost all cases."

Go to the Gigabyte web site and download the instructions for flashing the
BIOS. They will be identical to Abit, Aopen, and Asus at least.

Ok folks that's it I will go for it. Thx to all for the help.

Sorry, but there's a reason you can't use "every" and "identical" in this
context. It's because you'd be wrong. Sure, the instructions are often
the same for each variety of BIOS, but the chipset plays a role in this,
too. FWIW, the most recent Intel boards require no such playing with the
jumper. Thus, the language we used. Bottom line...read the manual for YOUR
motherboard. ...looks like Gigabyte mobos are different...

I followed BobN's advice and Flashed the BIOS, all is back to
normal again, it looks it was not the battery after all.
