Installing NT on a Ultrastor 22CA ESDI Controller

 Last reviewed: May 15, 1997
Article ID: Q114087

The information in this article applies to:
  • Microsoft Windows NT operating system version 3.1
  • Microsoft Windows NT Advanced Server version 3.1

SYMPTOMS

When you install Windows NT on some machines with an UltraStor 22CA ESDI caching controller, the emergency repair disk is not created and you receive the error "Unable to provide floppy support." If you continue, you may or not be able to get the system to boot. Booting from the 5.25" disk and then using the 3.5" disks to install fails with the same message. Disabling disk caching and 1024-cylinder truncation does not help.

CAUSE

Only ESDI cards that are Western Digital 1003 compatible are supported. Since each vendor implements caching differently, there is no way to write a generic hardware abstraction layer to handle ESDI controllers from all vendors.

RESOLUTION

Install an ESDI card that is compatible with the Western Digital 1003.
