The following is a list of IRQ, Interrupt ReQuests, which can be exampled much as the
COM ports and LPT port above can. When an I/O device wants to gain the attention of
the operating system, it signals this by causing an IRQ to occur. When the operating
system is ready to respond to the request, it interrupts itself and performs the service.

As above, the choices are On and Off.
When set On, activity will neither prevent the system from going into a power manage-

ment mode nor awaken it.

- IRQ3 (COM 2) - IRQ4 (COM 1)

- IRQ5 (LPT 2) - IRQ6 (Floppy Disk)

- IRQ7 ( LPT 1) - IRQ8 (RTC Alarm)

- IRQ9 (IRQ2 Redir) - IRQ10 (Reserved)

PCI IDE IRQ Map to

This items allows you to configure your system to the type of IDE disk controller in use.
By default, Setup assumes that your controller is an ISA device rather than a PCI control­ler.

If you have equipped your system with a PCI controller, changing this allows you to
specify which slot has the controller and which PCI interrupt (A, B, C or D) is associated
with the connected hard drives.

Remember that this setting refers to the hard disk drive itself, rather than individual parti­tions. Since each IDE controller supports two separate hard disk drives, you can select the
INT# for each. Again, you will note that the primary has a lower interrupt than the second­ary as described in
“Slot x Using INT#” above.

Selecting “PCI Auto” allows the system to automatically determine how your IDE disk
system is configured.
