KEYWORDS:kb3rdparty kbhw kbHardware

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Windows NT Workstation version 4.0 
 - Microsoft Windows NT Server version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

Installation of Windows NT 4.0 on a Quantum Atlas hard disk drive formatted with
Windows NT file system (NTFS) connected to an Adaptec 2940/3940 controller may
stop with any of the following error messages:

   STOP 0x0000007B
   INACCESSIBLE_BOOT_DEVICE

-or-

   OSLOADER 4.0 .... Disk I/O Error Status = 8000

-or-

   A kernel file is missing from the disk.
   Insert a system disk and restart the system.

CAUSE
=====

The Quantum Altas SCSI drives with firmware revision XL912 are incompatible with
Windows NT 4.0 and Adaptec 2940/3940 SCSI controllers.

WORKAROUND
==========

The Quantum Altas drive firmware needs to be updated to version XL915. The XL915
version works with Windows NT 4.0 and the Adaptec 2940/3940 controllers. The
firmware upgrade may be obtained from Quantum by calling their technical support
line.

To view the firmware version of the Quantum drive, use one of the following
procedures:

With an MS-DOS boot disk:

1. Boot your system with an MS-DOS boot disk that has the appropriate SCSI
   drivers for your controller.

2. When the ASPI driver loads, the identification code of the hard disk drive
   will be displayed. For example:

      Quantum XP23150W L915

   The firmware revision is the last four digits of this code.

   -or-

From within Windows NT:

WARNING: Using Registry Editor incorrectly can cause serious problems that may
require you to reinstall Windows NT. Microsoft cannot guarantee that problems
resulting from the incorrect use of Registry Editor can be solved. Use Registry
Editor at your own risk.

1. Start Registry Editor (Regedt32.exe).

2. Under the HKEY_LOCAL_MACHINE subtree, go to the following subkey:

   Hardware\devicemap\SCSI\SCSI Port 0\SCSI BUS 0\Target ID 0\Logical
   Unit ID 0\

   (This procedure assumes that Quantum Disk is on SCSI Port 0 with Target ID
   0.)

   The Identifier Key displays the identification code for the drive. The last
   four digits of this code are the firmware level, for example:

      Quantum XP23150W L915
