PRO EX Installation and User’s Manual
4.5. Driver Installation
No drivers are necessary to use the PRO EX. Add-on cards installed in the PRO
EX are seen as if they were connected directly in the host computer, and drivers
for each particular add-on card are still needed.
The PRO EX Uplink Host Adapter and the PRO EX Expansion Enclosure
registers as PCI-to-PCI Bridge, add-on cards are registers as devices behind
these bridges.
4.5.1. Mac Pro – Expansion Slot Utility settings
This section applies exclusively to the Apple Mac Pro built
before January 2008, this section can be skipped for all other
computers.
The Mac Pro (Intel Xeon-based) will detect changes in the PCI-e slot
configuration, it will automatically launch the Expansion Slot Utility
where you can make performance adjustments for the various PCI-e slots. The
utility can be manually started also, it can be found at: Under my Mac Pro:
/System/Library/CoreServices.
Ensure there is at least a x4 speed assignment for the slot where the PRO EX
Uplink Host Adapter is installed, making sure also that your video capture /
playback card and video display card also get a sufficient x value.
Example below is a good balance, it shows the PRO EX in slot 3 set for x4
speed, a popular video capture card in slot 4 also in x4 speed, and the standard
graphic card in slot 1 at x16 speed.
