Appendix A - Troubleshooting
The Developers Toolkit Software is supplied with the adapter and will be used in the troubleshooting procedures.
Using this software and following these simple steps can eliminate most common problems without the need to call
Technical Support.
1.
Identify all I/O adapters currently installed in your system. This includes your on-board serial ports, controller
cards, sound cards etc. The I/O addresses used by these adapters, as well as the IRQ (if any) should be
identified.
2.
Configure your adapter so that there is no conflict with currently installed adapters. No two adapters can
occupy the same I/O address.
3.
Make sure the adapter is using a unique IRQ. While the adapter does allow the sharing of IRQs, many other
adapters (i.e. SCSI adapters and on-board serial ports) do not. The IRQ is typically selected via an on-board
header block. Refer to the section on Card Setup and the Control/Status port for help in choosing an I/O address
and IRQ.
4.
Make sure the adapter is securely installed in a PCI slot.
5.
Use the supplied software and User Manual to verify that the adapter is configured correctly. The supplied
software contains a diagnostic program “SSDR56” that will verify if an adapter is configured properly. This
diagnostic program is written with the user in mind and is easy to use.
6.
Windows users can use the installed programs in the SeaMAC folder to verify operation.
