DOCUMENT:Q161510 25-FEB-2002 [winnt] TITLE :Floppy Not Detected on Ascentia 910N Laptop PRODUCT :Microsoft Windows NT PROD/VER::3.5,3.51,4.0 OPER/SYS: KEYWORDS:kb3rdparty ====================================================================== ------------------------------------------------------------------------------- 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.
