Figure 6: Jumper Setting for Restoring BIOS Defaults
To restore default BIOS settings:
1. Remove the CPU from the CTP2000 device chassis. See “Servicing the CTP2000
CPU” on page 23.
2. Locate the BIOS reset pins, which are shown as two black circles inside a figure 8 and
captioned as CMOS Clear.
NOTE: The two BIOS reset pins are the only reset pins that are used in
this procedure.
3. Attach the BIOS reset jumper included in the CTP2000 upgrade kit to the BIOS reset
pins in order to short them together.
4. Insert the CPU into the device. See “Servicing the CTP2000 CPU” on page 23.
5. Apply power to the device for 10 seconds.
6. Power off the device.
7. Remove the CPU from the chassis.
8. Remove the BIOS reset jumper so that the BIOS reset pins are no longer shorted
together.
9. Insert the CPU into the device. When you power on the device, the default BIOS settings
will be in effect.
