Intel MB440LX manual Cmos

CMOS

The jumper on the J2J1, CMOS PROT pins preserves the CMOS settings during system reset. Moving the jumper to the CLR pins clears CMOS and sets it and the real-time clock (RTC) to the manufacturing default settings during system reset.

To reset the system’s CMOS and the RTC to factory default values, do this:

1.Observe the precautions on page 3, “Safety Guidelines.”

2.Remove the left side cover as described in Chapter 4, “Working Inside Your System.”

3.Move the jumper on the J2J1, CMOS PROT pins to the CLR pins.

4.Replace the left side cover, and connect the power cord(s) to the system.

5.Turn the system on, and wait for POST to complete. This automatically reprograms CMOS and RTC to their default settings. For instructions on running POST, see Chapter 3, “Configuring The System.”

6.Turn the system off, disconnect the power cord(s) from the system, and remove the left side cover.

7.Move the jumper on the J2J1, CMOS CLR pins to the PROT pins.

8.Replace the left side cover, and connect the power cord(s) to the system.

9.Run the SCU to configure your system. For information on running the SCU, see Chapter 3, "Configuring The System."
