Installation Procedures

Specify Shared or Board-Unique Hardware

Interrupt Assignment

The installation process then asks you to specify how hardware interrupts

are to be assigned.

The IPC-1600, Intelligent Ports Card - Version 1.0

package allows the ports boards to be configured to all use the same interrupt (shared) or for each board to be configured to a different interrupt. If interrupts are shared, a maximum of 7 ports boards

may be installed. If each board is configured to a different interrupt, then at most 5 can be installed.

Do you want to share interrupts among all boards? (y or n)

If you specify to share an interrupt level among all boards, you are then asked to select the interrupt to be used by all IPC-1600 boards as follows.
