The information in this article applies to:

SUMMARY

After you install Windows NT version 4.0 on an EIDE based system the following error message is posted to the system event log: 

   Event ID: 26
   Source: Atapi
   Type: Warning
   Description: The driver has detected that device \device\scsiport0
                has old or out-of-date firmware.
                Reduced performance may result.
This is only an informational warning message and is not considered fatal, although it will effect performance.

MORE INFORMATION

While ATAPI enumerates devices attached to the EIDE controller, it checks to see if devices attached to the controller support advanced AT attachment interface commands.

The ATAPI device driver logs this error when a drive fails some ATA advanced features. (e.g. multi block I/O)

This may also be caused by a faulty device.

To isolate which device is causing this message, you can remove one device at a time from the controller reporting the error or swap devices between controllers to see when the error message follows a particular device. In some cases, the OEM manufacturer may have newer firmware available to resolve the problem.

You can extract information from the Windows NT registry to determine the manufacturer and firmware revision your device has that is causing the error message by using Registry Editor.

WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.

  1. Start Registry Editor (Regedt32.exe) and go to the following subkey: 

          HKEY_LOCAL_MACHINE\Hardware\Devicemap\Scsi\ScsiPortx
      \ScsiBusx\TargetIdx\LogicalUnitIdx, (where x varies according to
      device number).

  2. Look at the <Identifier REG_SZ: value> to see the model number and firmware revision values. For example, if you see: 

          Identifier:REG_SZ:Western Digital WDCAC34000L  23.3

    Then the 23.3 is the firmware revision value.

    Record the device model number and firmware revision, then check with the manufacturer for any known issues or the availability of newer firmware for the offending device.

  3. Quit Registry Editor.
