Chapter 3 Configuration and Default Settings

• Load Setup Defaults—This setting restores all BIOS settings to the
factory default. This is useful if the controller exhibits unpredictable
behavior due to an incorrect or inappropriate BIOS setting. Notice
that any nondefault settings such as boot order, passwords, and
keyboardless operation are restored to their factory defaults. This may
produce undesirable behavior, and in heavily customized cases, may
cause the controller to malfunction or fail to boot.
• Discard Changes—Any changes made to BIOS settings during
this session of the BIOS setup program are discarded. Unlike Exit
Discarding Changes, however, the BIOS setup continues to be active.
• Save Changes—Changes made to BIOS settings during this session
are committed to battery-backed System CMOS. The setup program
remains active, allowing further changes.
System CMOS
The NI VXIpc-882 contains a backed-up memory used to store BIOS
configuration information.
Complete the following steps to clear the CMOS contents:
1. Power off the chassis.
2. Remove the controller from the chassis.
3. Move the jumper on W1 from pins 1–2 to pins 2–3, as shown in
Figure 3-10.
4. Wait one second. Move the jumper back to pins 1–2.
5. Reinstall the controller in the chassis.
Caution Do not leave the jumper on pins 2–3. Doing so decreases battery life. In addition,
leaving the jumper on the pins prevents the controller from booting.
