ICH9DO Overview

Intel® ICH9DO Southbridge is an advanced I/O controller hub (ICH) connected to the

Intel® Q35 Northbridge through a DMI connection. The Intel® ICH9DO has six PCIe x1

ports, supports up to twelve USB 2.0 devices, six SATA 3Gb/s drives with Intel® Matrix

Storage Technology (ACHI, RAID 0, RAID 1, RAID 5 or RAID 10), and comes with an

integrated GbE controller that is interfaced to an external RJ-45 connector. A

High-Definition audio (HDA) controller can be connected to an HDA codec on an optional

audio kit. Four PCI Masters provide PCI expansion capabilities on a compatible PICMG

1.3 backplane.
