NOTE
The BIOS has the capability (not currently enabled) of password protecting casual access to the
unit’s CMOS set-up screens. The CMOS Clear jumper allows the user to clear the password in the
case of a forgotten password.
1.3.1 CMOS Password
To clear the CMOS password:
1. Turn off power to the unit.
2. Momentarily short the pins of E3 for approximately five seconds.
3. Power up the unit.
When power is reapplied to the unit, the CMOS password will be cleared.
