Internal I/O Connectors - Intel D845GEBV2 - OCTOBRE 2002 Manual

✏
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, power, and hardware control (see page 62)
 Auxiliary line in
 ATAPI CD-ROM
 Front panel audio
 Fans
 ATX12V power
 Main power
•
Add-in boards and peripheral interfaces (see page 67)
 CNR (optional)
 PCI bus
 AGP
 IDE
 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 (six on the Desktop Board D845GEBV2, three on the
Desktop Board D845GERG2). 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.
•
One CNR (optional), shared with PCI bus connector 6 (ATX expansion slot 1) on the Desktop
Board D845GEBV2, or with PCI bus connector 3 (ATX expansion slot 1) on the Desktop
Board D845GERG2.

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 6 on the D845GEBV2
board and slot 3 on the D845GERG2 board. 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 15 (page 67) and Figure 16 (page 68) illustrate the board's PCI slot numbering.
