Discarding Changes, however, the BIOS setup continues to be active.

System CMOS
The NI PXIe-8105 contains memory backed up by a battery 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 W2 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.
Caution Do not leave the jumper on pins 2–3. Doing so decreases battery life and prevents
the controller from booting.
