PCI slots
The PCI slots support PCI cards such as a LAN card, SCSI card, USB card, and
other cards that comply with PCI 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.
