Appendix A – Troubleshooting 
Following these simple steps can eliminate most common problems. 
1.  Read this manual thoroughly before attempting to install the adapter in your 
system. 
2.  Install software first. This places the required installation files in the correct 
locations. After installing the software, proceed to the physical installation 
section of this manual. 
3.  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. 
4.  Configure your Sealevel Systems adapter so that there is no conflict with 
currently installed adapters. No two adapters can occupy the same I/O 
address. 
5.  Try the Sealevel Systems adapter with a unique IRQ. While the Sealevel 
Systems adapter does allow the sharing of IRQs, many other adapters (i.e., 
SCSI adapters and on-board serial ports) do not. 
6.  Make sure the Sealevel Systems adapter is securely installed. 
7.  For Windows 2000/XP, the diagnostic tool ‘WinSSD’ is installed the 
SeaMAC 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. 
8.  Always use Sealevel Systems diagnostic software when troubleshooting a 
problem. This will eliminate any software issues from the equation.
