Computer Hangs after Many Card Installed
Any expansion chassis configuration requires the cooperation of the computer system’s BIOS in order to operate properly, regardless of the
platform (PC/Laptop/Server) or operating system (MS Windows/MACOS/LINUX etc.).
The BIOS hosts the first and the most fundamental code (firmware) that a computer executes upon boot-up. It is then that each PCI/PCIe add-in
card (be it located on the host system or on OSS’s expansions chassis) is allocated Input/Output memory space for proper operation.
The BIOS hosts the first and the most fundamental code (firmware) that a computer executes upon boot-up. It is then that each PCI/PCIe add-in
card (be it located on the host system or on OSS’s expansions chassis) is allocated Input/Output memory space for proper operation.
By installing multiple add-in cards in one chassis or chaining multiple OSS chasses (as discussed in: Appendix A), we are requesting more and
more resources from the BIOS and thus must make sure we pre-allocate them sufficiently.
It is therefore imperative that our computing platform allocates at least 32KB of I/O memory space to allow multiple add in cards to operate
properly. This setting may be editable or preset by your BIOS (or computer) vendor. If you are having this problem it is recommended that you
first update your system to the latest firmware provided by your vendor. Instruction on how to do that (as well as making a backup of your
current BIOS firmware) should be provided by your computer vendor on their web site.
In case this property is editable, your computer vendor should also be able to tell you how to select at least 32KB using their BIOS interface.

Nothing Works
Recheck all power connections.
Verify cable installation.
Verify host card is properly configured for the # of lanes in the host computer slot.
If it powers up OK, but nothing works, check the computer’s Device Manager or System Profiler to see if the expansion chassis has been found.
If not found, try the troubleshooting steps for My Computer Can’t Find the expansion chassis. If the expansion chassis is visible, but has a
problem, try to resolve the problem (See Note above). If that fails, go to
Troubleshooting
to get additional help.
