Turned on with CMOS jumper shorted - Is this fatal

[EnglishLion]

In a moment of overclocking madness, I forgot to reset my CMOS jumper before turning on. This is on my Abit Fatality F-i90HD motherboard.

Now it will post to BIOS after I reset the CMOS (properly this time) but if I change anything in the BIOS and save it, it won't post. I've tried just changing the date and nothing else, still won't have it.

I'm off to the shop later to buy a replacement battery, just in case but I've not got high hopes on that one. I feel I may have fried whatever the CMOS info is stored in (EPROM or whatever).

Anyone know of a solution?

you know this is a huge prob....my mobo is doing something similar and i cant point out 2 more ppl on this forum that are having the same prob as me.....my first idea would to cut power remove the battery for like 10 min...while its out put the jumper in the short/clear position and pop the battery back in...then wait a few seconds....put the jumper back and plug your rig back in and boot it....

Go here and get a new BIOS chip;

That sounds like a dead battery.

Leaving the jumper on may have allowed to stored energy in the battery to leak into the system, there isn't a lot on those so it's not likely it killed your CMOS. The fact that you can get into your BIOS is a pretty good indicator that its still working, but not being able to save is pretty tied to your battery being dead. What happens when you save and exit, the battery tries to kick in to power and apply the new settings. Upon failure, well, yeah. Failure.

Replace the battery, you should be able to get one for 5 bucks. Just take the one you have to a Radioshack or even a department store. They'll match it up to the one you need. Can order them online even cheaper, albeit with a bit of a wait.

I don't think it's the BIOS chip as I can navigate the BIOS perfectly if the CMOS has nothing saved to it. But that link might well come in handy for another board I have - thanks

I have MSI K8N Diamond plus,It sometimes get the problem you said.After some bad OC and restarted 3 times without OS,CMOS resets then setting everything-->F10 and exit it wont save,Have to select save and exit and then only it will save it.So I guess you just have to act cool with these minor probs and sometimes time will solve it.

If the Battery is good(measure voltage) and it still won't "save" your BIOS settings than the chip is bad.
Had that prob before.

well, I've just been and picked up a new battery (glad for 24hr opening!) but am still having the same issue.

Sounds like a dead board walking. Or chip.

From my understanding the BIOS is on a non-volatile memory chip, ie data is retained upon loss of power. The BIOS settings (CMOS) are stored elsewhere and have to be battery backed up, so I don't see that getting a replacement BIOS chip will help.

After all I can access the BIOS no problem, I just can't save any of the settings.

Looks to me like I have a dead board, I'll probably contact abit support just in case, but if their support is much like the other manufacturers then I won't hold my breath.

I actually did manage to fry my BIOS once, and on this system I managed to mess it up so badly I had to get it replaced. There is a site however that can send you a new one:
http://www.bioschip.com , but I tried a last time at the store where I always buy my "stuff" from..and they actually could help me there. They did whatever Bioschip.com does (copy original BIOS onto a new chip).

A good solution is to get a "BIOS Savior" device, it's connected between your original BIOS and makes a copy to an EE/EPROM of its own. I don't know the price of them these days. But back then it was like around 20 bucks for one. I think most of people around here who modify/OC their systems a lot would see this is as an important "tool".


Ok, but this is only if you would need a new BIOS EE/EPROM.. But like the rest say - ask your MoBo manufacturer first for advice.

iv had a similar problem with my Fatal1ty AAX8E for weeks now i need to clear CMOS every time i want to boot iv gave up on trying to fix it ive tryed allsorts and have decided to smash it into little bit's with a hammer when my new pc is built. Also just out of curiosity check the 4-pin ATX power connector located right behind the optical out port mine was a bit burnt and i suspect that is my problem make sure you unplug it and check the connection.

good luck baz
