Chapter 8 System Board Jumpers
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."
