Intel® Desktop Board D865PERL Specification Update 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. For information about Addition of the SMBus to the PCI Connector ECN Refer to http://www.pcisig.com/data/s pecifications/smb_ecn_0405 01.pdf ✏ 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. 21
