Appendix A: Troubleshooting
A software testing utility is supplied with the adapter and will be used in the troubleshooting proce-
dures. By using this utility and following these simple steps, most common problems can be elimi-
nated 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 & on-board serial ports) do not. The IRQ is
typically selected via an on-board header block. Refer to the section on Card Setup for help
in choosing an I/O address and IRQ.
4. Make sure the adapter is securely installed in a motherboard slot.
5. For Windows 95/98/2000/ME and Windows NT, the diagnostic tool ‘WinSSD’ is installed in
the on the Start Menu during the setup process. First find the ports using the Device Manager,
then use ‘WinSSD’ to verify that the ports are functional.
Always use the diagnostic software when troubleshooting a problem. This will help eliminate any
software issues and identify any hardware conflicts.
