Certain address are used by the PC, others are free and may be used by the

CIO-INT32 and other expansion boards. We recommend BASE = 300H (768D) be

tried first.

RANGE

The CIO-INT32 BASE switch may be set for address in the range of 000-3F8 so it

should not be hard to find a free address area for you CIO-INT32. Once again, if you

are not using IBM prototyping cards or some other board which occupies these

addresses, then 300-31F HEX are free to use.

Addresses not specifically listed, such as 390-39F, are free.

3.2 INTERRUPT LEVEL SELECT

If the software you are writing employs interrupt service routines, you will need to

select and enable interrupts from the CIO-INT32 to the PC bus.

The table below lists typical IRQ assignments. The IRQs described as

UNASSIGNED are typically available to you.
