834053 2009-11-26 22:53:00 How do I reset the BIOS on my PC? convair (13650)
834054 2009-11-26 23:00:00 Go into the bios and select the default settings. Then reconfigure it, then save Speedy Gonzales (78)
834055 2009-11-26 23:00:00 Log into the BIOS on startup, usually del key, or sometimes F2.

Look and some place there it will tell you what key to press to reset to default.

834058 2009-11-27 07:05:00 If you need to reset the BIOS because the settings are preventing the PC from booting, you must do it another way...

Some modern motherboards have a "Clear CMOS" button on them, this will do it (Computer must be OFF when you press this)

Everything else will have 3 pins usually called CLR_CMOS or something similar, and a jumper over 2 of the 3. When you want to clear the data, you swap the jumper around. So you may go from Pins 1-2 to Pins 2-3. Then after a couple of seconds, put it back again (again the PC must be OFF)

Others just have 2 pads on the board somewhere called "CLR_CMOS" or similar, and you just short them out with a screwdriver etc for a couple of seconds.

Alternatively, taking the battery out for a while usually works as well.


There are also some DOS-Based BIOS tools (like uniflash) which can also clear the CMOS data. Of course this is only of use if the PC can actually start up.

834059 2009-11-27 07:09:00 -- or on some motherboards you have to set a jumper and restart to a BIOS menu for resetting. Then turn off, change the jumper back to normal and restart. I came across a Intel board the other day that does this.

The important thing is to read the instructions - damage can be done!

Never heard of that one before, but since it's Intel, it doesn't surprise me :rolleyes:

I read the instructions, when I remember to.
