Using System Resources

Most ISA devices installed in the system require you to reserve an IRQ. PCI devices also
need to use an IRQ, but since they share system resources they can use the same IRQ. At least
one IRQ must be left unassigned, for use with any PCI devices installed in your system.
The system has a limited number of open IRQs. To install more ISA devices than you have
open IRQs, you must disable one unused system port for each excess ISA device, unless the
device does not require an IRQ.
To reserve an IRQ for an installed device:
1. Restart the system and start the BIOS Setup program.
2. On the PCI/PnP screen, select the IRQ you want to reserve.
3. Change the setting for the selected IRQ to ISA/EISA.
4. Save the changes and exit from the BIOS Setup program.
The following expansion cards require specific system resource settings, as noted:

PCI Devices

The system's PCI expansion slots comply with the PCI 2.1 specification. Devices that comply
with the PCI 2.1 specification are fully plug-and-play. You do not have to configure them
after installation.
