4.Align the card connector with the slot and press firmly until the card is completely seated on the slot.

5.Secure the card to the chassis with the screw you removed earlier.

6.Replace the system cover.

2.5.2Configuring an expansion card

After installing the expansion card, configure the it by adjusting the software settings.

1.Turn on the system and change the necessary BIOS settings, if any. See Chapter 4 for information on BIOS setup.

2.Assign an IRQ to the card. Refer to the tables on the next page.

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.
