Device31 and Bus1, Device8).
BUS: DEVICE:FUNCTION FUNCTION DESCRIPTION
Bus 0: Device 30: Function 0 Hub Interface to PCI Bridge
Bus 0: Device 31: Function 0 PCI to LPC Bridge
Bus 0: Device 31: Function 1 IDE Controller
Bus 0: Device 31: Function 2 USB Controller #1
Bus 0: Device 31: Function 3 SMBus Controller
Bus 0: Device 31: Function 4 USB Controller #2
Bus 0: Device 31: Function 5 AC´97 Audio Controller
Bus 0: Device 31: Function 6 AC´97 Modem Controller
Bus 1: Device 8: Function 0 LAN Controller
Additional onboard Components
There are two Onboard PCI connectors assembled on the D2 BASIC- CPU. A
complete PCI–Bus is implemented on the Onboard PCI connector for
assembling a POSboard.
The second Onboard PCI connector may be used to assemble alternatively
one Plug In Module with up to two PCI-Slot functionalities (double sided).
