The baseboard provides two riser slots; one providing PCI-X signals to a riser capable of 
supporting Low Profile add-in cards, and the other implementing Intel® Adaptive Slot 
Technology providing both PCI-X and PCI-Express signals to risers capable of supporting full 
height add-in cards. The following tables show the pin-out for each riser slot. 

The low profile riser slot pin assignments are shown below. On a given riser card, the PCI add-
in slot closest to the baseboard will always have device ID 17. On a three-slot riser card the 
middle PCI add-in slot will have device ID 18, and the top slot will have device ID 19. The 
interrupts on the PCI add-in slots should be rotated following the PCI bridge specification 1.0. 
To prevent anyone from putting a PCI add-in card directly into the riser slot, the connector has 
been pined out so that Pin 1 is furthest from the board edge. Side B should be closest to the 
memory DIMMs.
