Assigning Board-Unique Hardware Interrupt
Request Level
If you specified board-unique hardware interrupt assignments, the system
now displays a list of available hardware interrupts and prompts you to enter
the interrupt number to be assigned to the first board that you wish to install.
At the factory the hardware is set to IRQ10; if IRQ10 is already assigned, the
first available interrupt in the displayed list appears as the default. The
hardware IRQ setting(s) will be set in Chapter 4 to match the IRQ
assignment(s) made in this chapter.
The following is an example of how the display and prompt may appear
on your screen:
Please enter the following system configuration information for IPC-1600
Board 1. The available interrupt(s) for the IPC-1600 Board 1 are:
IRQ 3
IRQ 5
IRQ 10 (default)
IRQ 11
IRQ 12
Type the interrupt number and strike the ENTER key or type
Q to cancel installation. Striking the ENTER alone will
select the default.
Enter Interrupt:
Either press the ENTER key (to enter the default) or type in the name of
the interrupt that you wish to assign and then press ENTER.
Again, write down the IRQ settings so that you may refer to your records
during the hardware installation.
