How do I enter setup when I donot know t

On most motherboard, there is a jumper to set to clear the CMOS memory.
Some have 2 jumpers, one to clear the memory, and one to clear the password.

Some require a sequence to clear the password.
Set the jumper to clear,
Boot the computer,
Shut down,
Set the jumper back to normal.

If that doesn't work, you can usually clear the CMOS memory by removing the battery for 15 minutes or so with power off.

If all else fails, I saw a CMOS password utility posted in the utilities section at www.amptron.com

Try this utility. It kills the password.

Hold down any key when booting the computer. This often causes a keyboard error, and you are prompted if you want to enter setup.

This doesn't always work, but since it is so simple to try, it's worth a shot.

Good Luck-
