Configuring An Expansion Card; Pci Slot; Pci Express X1 Slot; Pci Express X16 Slot - Asus A58M-A/USB3 User Manual

1.5.2

Configuring 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.
