Problems Adding Second Drive to Dual Channel EIDE/PCI (162892)
The information in this article applies to:
- Microsoft Windows NT Workstation 3.51
- Microsoft Windows NT Server 3.51
This article was previously published under Q162892 SYMPTOMS
When adding an IDE drive to the second channel of an onboard EIDE/PCI
controller, Windows NT may not recognize the device. If you configure the
drive as a slave and add it to the primary channel, Windows NT may produce
the following error during system startup:
STOP 0x7B INACCESSIBLE_BOOT_DEVICE
CAUSE
The problem is caused by incompatibilities between the onboard dual channel
EIDE/PCI controller and the Windows NT 3.51 Atapi.sys driver.
RESOLUTION
To work around the compatibility problem, perform the following steps:
- Install the new IDE drive on the second IDE channel as the master.
- Make sure that a copy of Atdisk.sys is in the
%SystemRoot%\System32\Drivers directory.
- Use Control Panel Devices to start ATDISK and set the startup option to
System.
- Run Disk Administrator from the Administrative Tools group and assign a
drive letter to the new drive.
MORE INFORMATION
Some systems that exhibit this problem may function properly with the
latest service pack for Windows NT 3.51. Other systems may require you to
install Windows NT version 4.0 to achieve full functionality.
