• When PCIEX16_1 slot installed with PCI-E x16 graphic card, there will be no video

output from onboard CRT and DVI port.

• The PCIEX4_1 supports PCI-E transfer rate up to 4x ONLY.

• When PCIEX4_1 slot installed with PCI-E x4 or PCI-E x1 card, there will be no

video output from onboard CRT and DVI port.

• When the PCI-E x16 graphic card is installed on PCIEX4_1 slot, since its maximum

PCI-E transfer rate is up to 4x, its performance won’t be as fast as the same

1.12.3.3 PCI Slots: PCI1, PCI2, PCI3, PCI4

The PCI slot supports LAN card, SCSI card, USB card, and other add-on cards that comply with PCI

specifications.

1. When adding or removing expansion cards, make sure the system power is OFF.

2. After the card is installed on the system, make the adjustments under system BIOS

if necessary, then install the card driver provided by the card vendor under system

OS.

3. When using PCI cards on shared slots, ensure that the card driver support “Share

IRQ” or the PCI cards do not need IRQ assignments. Otherwise, conflicts will arise

between the two PCI groups; marking the system unstable and the card inoperable.
