Available IRQs
If you install an ISA device that requires an IRQ in the system, the BIOS automatically
configures the MIDI/Game port as a write-only device and makes IRQ 5 available. If you
install additional PCI devices that require additional IRQs, see “Freeing IRQs” below.
In dual-processor systems, the system board has one IRQ available (IRQ 11).
Freeing IRQs
To free IRQs for use by an ISA device or a PCI device that uses drivers that do not comply
with the PCI 2.l specification, you can use the system BIOS to disable unused system ports.
To disable an unused system port:
1. Restart the system and press
DEL
when prompted to enter Setup.
2. Select Setup, and then select Peripheral Setup.
3. Select the port you want to disable (OnBoard Serial Port 1, OnBoard Serial Port 2, or
OnBoard Parallel Port).
4. Change the value of the setting to Disabled.
5. Save the changes and exit from AMIBIOS Setup.
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.
Some older PCI device drivers cannot share an interrupt, which is a violation of the PCI 2.1
specification. If you install a device that uses such a driver, you must free an IRQ for the
device to work in the system.
