System CMOS

Caution Do not leave the jumper on pins 2-3. Doing so decreases battery life. Also, the
controller will not boot.
NI PXI-8186/8187 User Manual
The Exit setup menu includes the following settings:
• Exit Saving Changes—Any changes made to BIOS settings are stored
in the battery-backed System CMOS. The setup program then exits
and reboots the controller.
• Exit Discarding Changes—Any changes made to BIOS settings
during this session of the BIOS setup program are discarded. The setup
program then exits and boots the controller without rebooting first.
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.
The NI PXI-8186/8187 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 2-3.
4. Wait one second. Move the jumper back to pins 1-2.
5. Reinstall the controller in the chassis.
