APPLIES TO

  • Microsoft Windows NT Advanced Server 3.1



This article was previously published under Q106554

SYMPTOMS

When you configure Windows NT to use the BusLogic BT-542B SCSI host adapter, you may receive the following STOP message after you restart the system:

STOP: 0x0000007B (parameter, parameter, parameter, parameter) INACCESSIBLE_BOOT_DEVICE

CAUSE

This problem may occur because the BusLogic SCSI adapter is configured incorrectly. The BT-542B can be configured to use both an AT IRQ setting and a Host IRQ setting. These must match for Windows NT to correctly access any devices attached to the adapter.

NOTE: There may be other causes for the above error message.

RESOLUTION

To eliminate the error message and use Windows NT, set the AT IRQ and Host IRQ to the same IRQ.
