SYMPTOMS
When you start Windows NT and you log on, the following error message may appear:

Error: SAS Window: Winlogon.exe

There is no disk in the drive. Please insert a disk into drive A:



CAUSE
Systems that have bootable CD-ROMs and Award BIOS with a date code prior to September 25, 1996 may experience this problem. The Award BIOSes with release dates prior to September 25, 1996 enable bootable CD-ROM support by using floppy and hard disk emulation. Windows NT 4.0 does not support emulation mode CD-ROM booting.



RESOLUTION
Disable the bootable CD-ROM functionality of the system BIOS or of the SCSI controller BIOS.

To disable the bootable CD-ROM support of the Award BIOS:
 * 1) Restart the system.
 * 2) Press the DEL key to enter the BIOS Setup menu.
 * 3) Move the cursor to BIOS Feature Setup and press the Enter key.
 * 4) Click BOOT Sequence.
 * 5) Change the boot sequence so that the CD-ROM appears after the hard disk drive.



STATUS
Microsoft has confirmed this to be a problem in Windows NT version 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
