ID: Q156833

The information in this article applies to:

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

SYMPTOMS

You have a NEC Versa 4000 computer with the following configuration:

IDE controller-1: IDE hard drive (master) and IDE hard drive (slave)

IDE controller-2: IDE CD-ROM drive (master/standalone)

When you add the third IDE hard drive as master on the second channel and reconfigure the CD-ROM drive to be a slave, the following error message will be displayed:

STOP 0x0000007B Inaccessible Boot device

The same problem will be noticed with similarly configured systems using combination IDE disk and IDE CD-ROM drive peripheral devices.

CAUSE

This problem is caused by the Atapi.sys driver not functioning properly in this configuration.

WORKAROUND

To work around this problem, replace the Atapi.sys driver found in the %SystemRoot%\System32\Drivers directory with the Atapi.sys driver from Windows NT 4.0 Service Pack 3 or later.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 4.0. This problem was first corrected in Windows NT 4.0 Service Pack 3.
