Select the AHA-1740A/1742A/1744 installation configuration as follows:
1. Select the host adapter interface mode. There are two available. Standard Mode al-
lows software written for the AHA-1540 or AHA-1640 families to run the AHA-

When Standard Mode is selected, the host adapter interrupt level can be selected by
pressing Enter when the Host Adapter Interface Mode is highlighted.
