AX-78 loses BIOS settings every power outage.

I changed the battery w/ one from a working board. Did I lose a jumper or something?

Are you sure it looses the settings, or does it just say "Updating DMI Settings Update Sucessful" which is what these boards say each time they boot up. Beyond that, you changed the battery, then the BIOS chip is bad.

Ensure the following two step are met, for instance the jumper cap are at it's correct position as in pin 1 and 2 (default) normal instead of pin 2 and 3 (clear cmos memory)

Same goes to EZ-CCMOS1 at the back of the mobo which you find all the port like usb, lan, PS2 inbetween. Fyi this switch enables clearing the CMOS memory without uncovering the system chassis, so ensure is at it's correct position, neglecting it might face similar issue as what you are encountering now.

Turn left this switch to the “Clear
CMOS” position.
Turn right this switch to its default
“Normal” position. The default CMOS
memory is now reloaded

If u're indoubt look at the manual or the guide which i've attach here

If after trying the above and still no go, no harm getting a new cmos batt, after all is very cheap

I'll try that. It's been a real PITA as we've lately been have Enron-esque rolling blackouts a few times of day. It forgets the date and that I set the usb mouse to be run by BIOS, everytime.

Since I'm there... I was pretty decent at running the old soft menu on the KT7A. This is harder to figure
Is there an easy little fsb OC for a Phenom x4 9500 (I think). Summer heat on a giant heatpipe sunbeam fancooler?

I'm just running 2GB of Kingston Valu-Ram

I put the battery back in the other pc and it's still fine.

I don't need to reflash do I

I hate doing BIOS flashes. They always seem to go wrong, then I have to get a new chip. Biosman is great, I think the chip is less than $10 and it will have the newest available BIOS.

FF is the Full Function code, means its ready and should be good to go.

If you lose the CMOS jumper it might do this, but in most cases it will not post.

Battery will do this, but looks like you tried that.

Bad BIOS Chip can do this, as well as a bad BIOS needing reflashed.


Another piece of hardware can be at fault also....but I would stick with the BIOS chip...and you can order a new one from places like BIOSMAN.Com
