How to Clear the Hardware CMOS & Reset Password

Why? You will need to clear the CMOS anytime you FLASH upgrade the BIOS or when you forget your password to enter the BIOS for making settings.

How? When clearing the CMOS, it's NOT done by pulling the lithium battery or DALLAS chip off of the motherboard for a short period of time. Instead, there is a jumper on the motherboard that clears the CMOS. The jumper varies for all Tyan motherboards, so you will need to see which jumper applies to your motherboard. (Please refer to your motherboard manual for jumper location.)

Here we go...step by step.

Turn the power off
If you have 2 pins, short the two pins with a jumper for 10 seconds or so then pull the jumper and return it back to the default position.
If you have 3 pins, then move the jumper pin from default postion, jumpered 1-2 and move over to pins 2-3. Wait for 10 seconds or so, then move back to default position 1-2.
Turn the power back on and you should get an error message indicated by 2 beeps to run the setup for CMOS.
You will need to make the BIOS settings at this point and you're done!

NOTE: for ALL Tyan Pentium II/III LX, BX, and GX Intel Chipset motherboards, prior to clearing the CMOS, you must disconnect the AC power cord. Otherwise, the CMOS will not get cleared. You do not have to do this for other Tyan motherboard models with the Intel VX, HX, TX, and FX Chipsets.

Viel Erfolg!
