HP Ethertwist PC Lan Adapter/16 Plus Error Message

• Microsoft Windows 95

SYMPTOMS

When you use the HP Ethertwist PC Lan Adapter/16 Plus, you may receive an error message (one of various error messages), but the adapter card functions correctly.

CAUSE

The HP Ethertwist PC Lan Adapter/16 Plus can operate in an I/O mapped mode with no upper memory use (default), or in memory mapped mode with a 2 kilobyte upper memory buffer.

The Windows 95 driver provided to Microsoft by Hewlett-Packard does not have an option for I/O mapped mode.

RESOLUTION

To stop the error messages from appearing, reset the adapter card to memory mapped mode using the manufacturer-supplied Setup program (HPlanset.exe).

For instructions about how to use the adapter card Setup program, refer to the documentation that came with the card, or contact the manufacturer.

MORE INFORMATION

If you use HPlanset.exe to configure the adapter card for I/O mode, Windows 95 notifies you that the card is not responding correctly, but the card functions correctly anyway. As long as the card is in I/O mode, when you start the computer, the warning message appears.

After the warning messages are generated, the driver then automatically sets the adapter card to memory mapped mode for operation.
