Last reviewed: July 21, 1997
Article ID: Q158100

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

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

   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:

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

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.

Start Registry Editor (Regedt32.exe).
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
```
