1.5.3

PCI Express x1 slot

This motherboard supports PCI Express x1 network cards, SCSI cards, and other cards that

comply with the PCI Express specifications.

1.5.4

PCI Express x16 slot

This motherboard has a PCI Express 3.0/2.0 x16 slot that supports PCI Express 3.0/2.0 x16

graphic cards complying with the PCI Express specifications.

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.

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.
