Magma EB7-X8G2 User Manual page 22

Magma
Mac Operating System is prompting you to choose a PCI Express profile that maximizes the performance of your
attached devices. The Magma host card can communicate up to a bandwidth of x8 to and from the expansion chassis
and devices. You should choose a profile that matches the configuration of all the cards installed in your Mac. Magma
recommends that you install the system host card into a x8 slot in order to maximize throughput.
In this example, the Magma host card is installed in slot 4 and appears as "Intel PCI-to-PCI Bridge Card".
If your computer did not automatically prompt you to choose a PCI Express profile, you can locate this utility under
System  Library  CoreServices  Expansion Slot Utility.app.
Apple System Profiler
When using Mac OS X no additional software or drivers are needed. As long as you are using Mac OS X Version 10.4 or
newer, the operating system should automatically recognize the Magma expansion chassis.
