Appendix A - Troubleshooting

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 CyberResearch 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 CyberResearch adapter is using a unique IRQ. While the CyberResearch 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 by the BIOS or operating system. Some BIOS setup software will allow changing the IRQ,

but others do not. Another method of changing assigned resources is to try changing PCI slots. This will

typically cause the BIOS or OS to reassign the resources.

4. Make sure the CyberResearch adapter is securely installed in a motherboard slot.

5. When running DOS or Windows 3.x refer to the supplied CyberResearch and this User Manual to verify that

the CyberResearch adapter is configured correctly. This software contains a diagnostic program ‘SSD’

(D:\software\seacom\Other\DOS\DIAG, where D: = the driver letter of your CDROM drive) will verify if an

adapter is configured properly. This diagnostic program is written with the user in mind and is easy to use. You

can use D:\software\seacom\Other\DOS\PCI\FindPCI.exe to determine resources that have been assigned to

your adapter. Make sure that if available, the ‘Use Plug-n-Play” option is turned ‘OFF’ in your BIOS. Having

this option set to ‘ON’ in DOS or Windows 3.x will cause erratic operations.

6. For Windows95/98/ME/NT/2000, the diagnostic tool ‘WinSSD’ is installed in the SeaCOM folder 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.

7. Always use the CyberResearch diagnostic software when troubleshooting a problem. This will eliminate any

software issues from the equation.
