"Wait Confirmation failed" in Windows 2000 Event Viewer


What does the Event Viewer message "Wait Confirmation failed - check I/O port address settings" mean?




  • The I/O port address for the driver does not match the physical position of the DIP switches on the adapter.


  • The wrong driver has been selected.


  • Another adapter is using the same I/O port address.



  • Verify that the selected I/O port address matches the DIP switch settings on the adapter. DIP switch settings can be found in the manuals and install guides available on the Digi Technical Support web site.


  • Verify that the correct adapter has been selected during the driver installation.


  • Verify that the adapter is using a unique I/O address. Remember to power down the system before changing DIP switch settings.
