Installing NT on a Ultrastor 22CA ESDI Controller (114087)
The information in this article applies to:
- Microsoft Windows NT Server 3.1
- Microsoft Windows NT Workstation 3.1
- Microsoft Windows NT Advanced Server 3.1
This article was previously published under Q114087 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.
This problem was reported with the ALR 486/33. The UltraStor 22CA ESDI
caching controller installed and worked correctly on a Compaq, however.
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.
