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. Refer to the table on the next page for
details.
• By default, if you install a discrete graphics card on the PCIe x16 slot, the
onboard GPU will be automatically disabled. Connect the VGA cable to the
discrete graphics card first when using a discrete graphics card.
After installing the expansion card, adjust software settings if necessary.
1. Power 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.
