### Windows NT Problems and Solutions

Use this information to aid in troubleshooting your adapter setup.

#### Problem

The following error message appears in the Event Viewer:

`Wait confirmation failed....` (the exact wording of the error message varies with adapter type)

#### Causes/Solutions

- You have chosen the incorrect adapter type for the Digi product you have installed. Reinstall the driver (uninstall it first) with the correct adapter type.

- Match the dip switch settings on the card with the I/O setting selected in the driver configuration

#### Problem

The following error message appears in the Event Viewer:

`BIOS image failed to load....` (the exact wording of the error message varies with adapter type)

#### Causes/Solutions

- There is a conflict with the Memory Base Address you chose during installation. Reconfigure the driver with a different Memory Base Address.

- Shadow RAM is enabled for all or part of the memory address space assigned to the Digi adapter (depending on the adapter, the required address space is 8K or 32K, beginning at the Memory Base Address you set during driver installation). Check your computer's CMOS setup and make sure that shadowing is disabled for the addresses used by the Digi adapter.

- There is a hardware problem with the adapter. Contact Digi Technical Support.

#### Problem

The following error message appears in the Event Viewer:

`While validating that COM3 was really a serial port, the contents of the divisor latch register was identical to the interrupt enable and the receive registers. The device is assumed not to be a serial port and will be deleted.`

#### Causes/Solutions

- You may have configured one or more non-intelligent ports with the same name(s) as ports on the Digi adapter. The conflict must be removed either by re-mapping the conflicting Digi port or removing the conflicting non-intelligent port configuration.
  The conflicting non-intelligent port may have been configured by making changes within the Control Panel Ports applet. You may correct these changes either from within the Control Panel Ports applet, or with the Registry Editor. If you are unsure of how to do this, call Digi Technical Support.
