Resource Configuration

3.3.1

PCI Autoconfiguration

The BIOS can automatically configure PCI devices.

PCI devices may be onboard or

add-in cards.

Autoconfiguration lets a user insert or remove PCI cards without having

to configure the system.

When a user turns on the system after adding a PCI card,

the BIOS automatically configures interrupts, the I/O space, and other system

resources.

Any interrupts set to Available in Setup are considered to be available for

use by the add-in card.
