2.2.2 INTERRUPT LEVEL SELECT

The interrupt jumper need only be set if the software you are using
requires it. The Universal Library and other programs which take
advantage of the REP-INSW high speed transfer capability of the
board require an interrupt. If you do set the interrupt jumper, please
check your PC's current configuration for interrupt conflicts.

There is a jumper block on the CIO-DAS800 located just above the
PC bus interface (gold pins). The factory default setting is that no
interrupt level is set. The jumper is in the 'X' position at the factory.
It is shown in Figure 2-2 set for IRQ 5.
