IRQ assignments for this motherboard
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.
Never connect a 1394 cable to the USB connectors. Doing so will damage the
motherboard!
