After installing the expansion card, configure the it by adjusting the

software settings.

Standard interrupt assignments

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.
