Using AccuLogic IDE Controllers with Windows NT

• Microsoft Windows NT operating system version 3.1
• Microsoft Windows NT Advanced Server version 3.1

SYMPTOMS

Windows NT may hang on disk 9 during Setup when an AccuLogic IDE controller is installed and the ROM BIOS on this controller is enabled.

If you install from a CD-ROM, an Unexpected DOS Error 11 may occur within Windows NT when it accesses the floppy disk drive. This error message has been seen while installing the Windows NT Service Pack 1.

CAUSE

This problem occurs when the AccuLogic IDE controller is configured with the ROM BIOS enabled. The On-Board BIOS is typically used for IDE drive types not directly supported by the systems ROM BIOS (that is, the AccuLogic ROM BIOS is enabled).

RESOLUTION

If your computers BIOS supports an IDE drive type that is similar to your IDE hard drives actual or logical characteristics, it may be possible to disable the AccuLogic ROM BIOS and use your computers ROM BIOS to support the drive. This would allow setup from floppy to run successfully and will avoid the Unexpected DOS Error.
