Intel Desktop Board D865GVHZ Technical Product Specification ✏ NOTE The back panel audio line out connector is designed to power headphones or amplified speakers only. Poor audio quality occurs if passive (non-amplified) speakers are connected to this output. 2.8.2 Internal I/O Connectors The internal I/O connectors are divided into the following functional groups: • Audio (see page 63)  Auxiliary line in  ATAPI CD-ROM  Front panel audio • Power and hardware control (see page 65)  Fans [3]  ATX12V power  Main power  Chassis intrusion • Add-in boards and peripheral interfaces (see page 68)  PCI bus  Parallel ATA IDE  Diskette drive  SCSI hard drive activity LED (optional)  Serial ATA 2.8.2.1 Expansion Slots The board has three PCI rev 2.2 compliant local bus slots. The SMBus is routed to PCI bus connector 2 only (ATX expansion slot 6). PCI add-in cards with SMBus support can access sensor data and other information residing on the Desktop Board. ✏ NOTE The SMBus routing to the PCI bus connectors does not conform to the PCI Engineering Change Notice (ECN) "Addition of the SMBus to the PCI Connector ECN", dated October 5th, 2000. The ECN specifies that SMBus signals must be routed to all PCI bus connectors. On this board, SMBus signals are routed to PCI bus connector 2 only. Add-in cards that implement PCI bus connector pins A40 and A41 for any purpose other than SMBCLK (SMBus clock) and SMBDAT (SMBus data) should not be installed in PCI bus connector 2. For information about Addition of the SMBus to the PCI Connector ECN Refer to http://www.pcisig.com/data/specifications/smb_ecn_04 0501.pdf ✏ NOTE This document references back-panel slot numbering with respect to processor location on the board. PCI slots are identified as PCI slot #x, starting with the slot closest to the processor. Figure 17 (page 68) illustrates the board's PCI slot numbering. 62
