2.8.2 Internal I/O Connectors
The internal I/O connectors are divided into the following functional groups:
• Audio (see page 58)
 Telephony
 Auxiliary line in
 ATAPI CD-ROM
• Power and hardware control (see page 60)
 Fans
 ATX12V
 Main power
• Add-in boards and peripheral interfaces (see page 63)
 CNR (communication and networking riser)
 PCI bus (three on the D845HV board; six on the D845WN board)
 AGP
 IDE (two)
 Diskette drive
 SCSI LED
2.8.2.1 Expansion Slots
The board has the following expansion slots:
• One AGP connector. The AGP connector is keyed for 1.5 V AGP cards only. Do not install a
legacy 3.3 V AGP card. The AGP connector is not mechanically compatible with legacy 3.3 V
AGP cards.
• PCI rev 2.2 compliant local bus slots (three on the D845HV board, six on the D845WN board).
The SMBus is routed to PCI bus connector 1 only (ATX expansion slot 6). PCI add-in cards
with SMBus support can access sensor data and other information residing on the board.
• One CNR (optional), shared with PCI bus connector 3 (ATX expansion slot 1) on the D845HV
board or with PCI bus connector 6 (ATX expansion slot 1) on the D845WN board.

NOTE
This document references back-panel slot numbering with respect to processor location on the
board. The AGP slot is not numbered. PCI slots are identified as PCI slot #x, starting with the
slot closest to the processor. The CNR slot shares an ATX expansion; slot 3 on the D845HV board
and slot 6 on the D845WN. The ATX/MicroATX specifications identify expansion slot locations
with respect to the far edge of a full-sized ATX chassis. The ATX specification and the board’s
silkscreen are opposite and could cause confusion. The ATX numbering convention is made
without respect to slot type (PCI vs. AGP), but refers to an actual slot location on a chassis.
Figure 13 on page 63 illustrates the board’s PCI slot numbering.
