Problems can arise if two devices attempt to use the same IRQ line. To avoid this type of conflict, check the documentation for the default IRQ line setting for each installed device. Then consult Table B-8 to configure each device for one of the available IRQ or other lines.

NOTE: Interrupts for the on-board sound and NIC are assigned dynamically by the sys- tem basic input/output system (BIOS).
