Chapter Five : Deleting a Password 127
Chapter 5 Deleting a Password
Overview
If you forget the passwords you setup through AMIBIOS Setup, the only way you can
restart the system is to erase the system configuration information where the passwords
are stored. System configuration data is stored in CMOS RAM, a type of memory that
consumes very little power.
Erase Old Password
You can drain CMOS RAM power via JP10 on the motherboard. JP10 is a 3-pin berg
with a default setting of pins 1 and 2 shorted by a jumper. Perform the following steps to
erase the old password.
Important
Make sure you are properly grounded before
performing the following procedure. You must be
certain that no electrostatic discharge (ESD) occurs.
ESD can ruin your motherboard. Wear an antistatic
wristband attached to a ground. See “Avoid Static
Electricity” on the following page.
Step Action
1 Turn the system power off and remove the system cover.
2 Short pins two and three on JP10 from one to five seconds to clear the CMOS.

Since you drained power from CMOS RAM, all system configuration information has been erased. You
must now re-enter the system configuration information by running AMIBIOS Setup.
