PCI Express slot
The PCI slot supports cards such as a LAN card, SCSI card, USB card, and other
cards that comply with PCI specifications.
PCI Express 2.0 x16 slot
This motherboard supports PCI Express x16 network cards, SCSI cards, and other
cards that comply with the PCI Express specifications.
PCI Express 2.0 x1 slot
This motherboard supports PCI Express 2.0 x1 network cards, SCSI cards, and
other cards that comply 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.
