Expansion Slots - Intel D865PERL Specification

2.8.2.1

Expansion Slots

The Desktop Board D865PERL has the following expansion slots:
•
AGP connector: The AGP connector is keyed for Universal 0.8 V AGP 3.0
cards or 1.5 V AGP 2.0 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.
•
Five 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 D865PERL.
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.

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. Figure 22 on page 68
illustrates the board's PCI slot numbering.
