SYMPTOMS
When you install Windows NT 4.0 on a Digital Equipment Corporation DEC AlphaServer, the setup process may stop responding and may not respond to user input.

Windows NT 4.0 may stop responding before or during a system boot at the Blue kernel screen although displaying the Operating system version, number of processors, and amount of memory. Additionally, the computer's NVRAM variables may get corrupted.

This can happen during an initial installation, although performing an Upgrade from Windows NT 3.51 to Windows NT 4.0, or after Windows NT 4.0 is already installed and running.



CAUSE
There is a version conflict between certain revisions of the Mainboard, I/O module, ARC firmware, and Windows NT 4.0 HAL files that can cause your system to malfunction if you run Windows NT on any of the following systems:
 * AlphaServer 2000 4/xxx and 5/xxx
 * AlphaServer 2100 4/xxx and 5/xxx
 * AlphaServer 2100A 4/xxx and 5/xxx



RESOLUTION
You must upgrade your ARC firmware to version 4.50 or later, and update your Windows NT 4.0 HAL files to the version posted on Digital's WWW site.

For information on updating your System firmware and to download the updated HAL files, please contact Digital technical support at:

MORE INFORMATION
The methods you use to update the firmware and HAL are different depending on whether:
 * Windows NT 4.0 is already installed.
 * You are performing a fresh installation of Windows NT 4.0.
 * You are upgrading from Windows NT 3.51 to Windows NT 4.0.
 * You have just replaced your I/O module or mainboard, and your system will not boot the ARC firmware.

NOTE: If you are already running ARC firmware 4.50 or later, you can skip the steps in the instructions related to upgrading the firmware. The ARC firmware version currently installed in your system is displayed on the ARC Boot screen.

If you are running ARC firmware 4.50 or later, do not downgrade to an earlier revision.

STEP A: Updating the System Firmware
For information on updating your System firmware, please contact Digital technical support at http://www.windows.digital.com/support

STEP B: Upgrading HAL on Systems with Windows NT 4.0 Already Installed

 * 1) Download the updated Hal.dll files from Digital.

Please contact Digital technical support at: http://www.windows.digital.com/support
 * 1) Expand the Hal.zip file you downloaded from DEC, and then put them onto a separate floppy disk.
 * 2) On the SYSTEM partition, go to the OS\Winnt40 directory.

NOTE: If you do not see any files in the right-hand pane, change the File Manager or Explorer settings as appropriate to show all files and file extensions. These files normally have the hidden, system, and read- only attributes set.
 * 1) In your OS\Winnt40 directory, rename the Hal.dll file to Hal.old.
 * 2) Unzip the Hal.zip file you downloaded from DEC into a separate, temporary directory on your hard disk drive. Then Copy the new Hal_name.dll file from the temporary directory on your hard disk drive into the directory OS\Winnt40 containing the Hal.old file in your system partition, and rename the file you copied to Hal.dll.
 * 3) Shutdown and restart your system.
