2.8.2.1 Expansion Slots
The board has the following expansion slots:
• One Accelerated Graphics Port (ATX Expansion slot 6). A 4X AGP retention mechanism can be
installed during board manufacturing (at OEM request).
• Five PCI Local Bus slots (compliant with PCI rev 2.2 specification). The SMBus is routed to
PCI bus connector 2 only (ATX Expansion slot 4). 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 5 (ATX Expansion slot 1).

NOTE
This document references back-panel slot numbering with respect to processor location on the
desktop board. The AGP slot is identified as “AGP” and is not numbered. PCI slots are identified
as “PCI slot #x, starting with the slot closest to the processor. The CNR slot shares a PCI slot
number.
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 11 on page 63 illustrates the
board’s PCI slot numbering.
