1.5.2Configuring an expansion card
After installing the expansion card, configure it by adjusting the software settings.
1.Turn on the system and change the necessary BIOS settings, if any. See Chapter 2 for information on BIOS setup.
2.Assign an IRQ to the card.
3.Install the software drivers for the expansion card.
When using PCI cards on shared slots, ensure that the drivers support “Share IRQ” or that the cards do not need IRQ assignments. Otherwise, conflicts will arise between the two PCI groups, making the system unstable and the card inoperable.
