1.7 PCI Express* Connectors
The board provides the following PCI Express connectors:
• One PCI Express x16 connector supporting simultaneous transfer speeds up to 8 GBytes/sec
• One PCI Express x1 connector. The x1 interface supports simultaneous transfer speeds up to
500 MBytes/sec
The PCI Express interface supports the PCI Conventional bus configuration mechanism so that the
underlying PCI Express architecture is compatible with PCI Conventional compliant operating
systems. Additional features of the PCI Express interface include the following:
• Support for the PCI Express enhanced configuration mechanism
• Automatic discovery, link training, and initialization
• Support for Active State Power Management (ASPM)
• SMBus 2.0 support
• Wake# signal supporting wake events from ACPI S1, S3, S4, or S5
• Software compatible with the PCI Power Management Event (PME) mechanism defined in the
PCI Power Management Specification Rev. 1.1
1.8 IEEE-1394a Connectors
The IEEE-1394a interface addresses interconnection of both computer peripherals and consumer
electronics. The IEEE-1394a interface provides a throughput ranging from 100 Mbits/sec to
400 Mbits/sec. As a manufacturing option, the board includes three IEEE-1394a connectors as
follows:
• One IEEE-1394a connector located on the back panel.
• Two IEEE-1394a front-panel connectors located on the component side.

1.9 Legacy I/O Controller
The legacy I/O controller provides the following features:
• One serial port
• One parallel port with Extended Capabilities Port (ECP) and Enhanced Parallel Port
(EPP) support
• Serial IRQ interface compatible with serialized IRQ support for PCI Conventional bus systems
• PS/2-style mouse and keyboard interfaces
• Interface for one 1.44 MB or 2.88 MB diskette drive
• Intelligent power management, including a programmable wake-up event interface
• PCI Conventional bus power management support
The BIOS Setup program provides configuration options for the legacy I/O controller.
