NOTE:
Switches 7 and 8 on SW1 are not used so they may be On or Off. The
example shows them On.
Make a note of the base address used so you can verify/set that address in the
HotWire Hardware Setup window after the HotWire software is installed.
Setting the IRQ Switches
IRQ (hardware interrupt request) is a signal used by your device to inform your
CPU when it wants to transfer or receive data. Use Switch Banks 2 and 3 (SW2
and SW3) to select an IRQ. You can use the following illustration to locate these
switches. The callouts show the switch settings when IRQ is set to 5.
NOTE:
The IRQ setting must not conflict with any other device in the PC.
