The AJA engineering, QA and technical support teams have determined the optimum slot placement for the AJA KONA cards in the Apple MacPro.  In order to assure proper functionality, the card should be seated in the slot specified by AJA.

Expansion Slot Placement for:
MacPro (2008)

For optimal performance of the KONA LHe card AJA recommends slot 2. See Option 1 for slot placement. The KONA 3 operates properly in slots 2 and 3.

Expansion Slot Placement for:
MacPro (pre-2008)

If you are unsure of the slot configuration as used in your machine, it can be determined by using the Expansion Slot Utility application. This application is found in the following directory location on your Mac Pro: System/Library/CoreServices.  The correct configuration is with the slots configured as follows:

x4 for slot 4
x4 for slot 3
x1 for slot 2
x16 for slot 1

XServe Intel (pre-2008)

AJA only supports the PCI-X and PCI versions of the KONA cards in slot 1 of the Intel XServe.  The PCIe versions of the KONA cards (KONA3, KONALHe) should not be used in the Intel XServe.  The AJA PCI-X and PCI cards (KONA3X, KONALH) can be used in the Apple Intel XServe with the Apple PCI-X riser, P/N 922-7860.
