GPIB Interrupt Level
You can program the GPIB interface on the VXIpc-800 to use one of
two ISA interrupts—5 or 11. Switch S8 controls which interrupt line the
GPIB interface uses. Figure 3-11 shows these settings.

System CMOS
The VXIpc-800 contains a backed-up memory used to store BIOS
defaults and configuration information.
To clear the CMOS contents, simply short the pins of W2 as shown in
Figure 3-12b.
Warning: You should not keep these two pins shorted because the CMOS memory
cannot be sustained when the power is turned off if these two pins are
shorted.
