How to recover from bad BIOS settings?

I have a PC with an ASUS A7N8X-X mobo, which worked perfectly at its
nominal speed, no overclocking. Then I had the insane idea to try,
just for fun, to push a bit the speed limits. I set the CPU clock at
200 MHz (instead of 166), the multiplier at 12, and the memory timings
at "Aggressive".
Result : the PC does not boot anymore, emitting a continous string of
long beeps. I would like to reset the BIOS settings to the default
values, but how can I do that? The power on sequence does not proceed
past the long beeps... why doesn't the BIOS revert to the default
values when there is an error, like my previous mobo (an Abit) did ?

Thanks for any help and suggestions

pull the battery out for a couple minutes or read the user guide for the
jumpers that reset the bios to default.

Don't forget to unplug the computer! You cannot leave +5VSB running
on the board when you reset the CMOS, as it will burn the dual diode
on the motherboard.

Have you tried clearing the CMOS by moving jumper CLRTC?

That worked, thanks, my PC is resurrected.
But shouldn't this mobo have a "crashproof" mode, I remember to have
read words to that effect, where the BIOS reverts to safe values in
case it is unable to initialize? Or were they just advertizing lies?
It isn't so comfortable to disconnect all the cables, put the PC on a
table, open the case, etc..... oh well....

Instead of clearing the CMOS and messing with jumpers isn't is simpler
to remove the ram sticks and boot? Then shut it down and put the
memory back in and boot again. A tech friend of mine at my local shop
showed me that trick and it seems to work.

I can't see how that could work... but if it works for him, great.

Besides, swapping the jumper seems easier to me. :)

Next time this happens, try holding the Insert key when you turn it on.
This may let you enter your BIOS by loading default settings.

Speaking of tricks, pressing "Pause" when you want to read the 2nd screen
of the BIOS info is a good one. The one that tells you what drives are
installed, com port addresses, memory slots in use etc.

Nope... did try that, didn't work...

Are you speaking from your personal experience?

Thanks for that tip. I used it yesterday to get a pc up and running. Much
easier than hunting for the motherboard jumper setting to reset the CMOS.

Woot, thx.
