Q161510: Floppy Not Detected on Ascentia 910N Laptop

Article: Q161510
Product(s): Microsoft Windows NT
Version(s): 3.5,3.51,4.0
Operating System(s): 
Keyword(s): kb3rdparty
Last Modified: 25-FEB-2002

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Windows NT Server versions 3.5, 3.51, 4.0 
- Microsoft Windows NT Workstation versions 3.5, 3.51, 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you install Windows NT on an AST Ascentia 910N laptop computer, the floppy
drive is no longer detected. If you run Control Panel and choose Devices, the
system indicates that the floppy disk driver is not started. If you attempt to
start the driver, the following error is returned:

  Error 0121
  Could not start floppy service,
  the semiphore timeout period has expired.

CAUSE
=====

This problem occurs if you attempt to run the Ascentia 910N from battery power
rather than AC power. Power management is not supported in Windows NT, thus when
Windows NT is booted with the system running on battery power, the floppy disk
is not recognized.

RESOLUTION
==========

According to AST Technical Support, upgrading the BIOS to revision 2.5 should
alleviate the problem. If the problem still occurs after upgrading the BIOS to
2.5, download the file Set4nt.exe from the AST Web page. This file is a
self-extracting executable that contains the Set4nt.com utility as well as a
readme file. This utility was used to correct the problem on computers with BIOS
earlier than 2.5.
