Any PCI Cards you install in the expansion chassis will appear behind
the pci-bridge device.
Mac OS 10.4.x
If any of these devices are not displayed as shown above, you should
shut down your system (computer first, then the expansion chassis) and
reconnect the cables and the PCIe expansion host card to ensure that
you have a solid connection. Then restart the Magma expansion
chassis followed by the computer. Next, try to verify the installation
again, as shown above. If you are still having problems, contact Mobility
Technical Support at (858) 530-2511.
