Setting the hardware interrupt
The PCI card requires a hardware interrupt (IRQ) in the range of 3 to 7 that is
not in use by another device on your PC.
Table 6 : PC hardware and IRQ settings
The configuration tool shows you the available IRQ settings, and allows you
to choose the IRQ setting for the PCI card.
CAUTION!
Do not use a pencil to change the
switch settings. Graphite deposits are
electrically conductive and can cause a
short circuit in the switch.
