Windows NT SCSI Driver Changes With the release of Windows NT version 4.0, the drivers for certain SCSI adapters have been moved from the base operating system to the Windows NT Driver Library (\DRVLIB) included on the Windows NT version 4.0 Beta compact disc. Check the following list to determine if any of your adapters are affected by this change. If your computer has an adapter that appears on this list, you must create a driver disk before installing Windows NT version 4.0. Use this disk to install the appropriate driver(s) during Setup, or keep the disk handy and install the driver using the Control Panel once Setup is complete. The following drivers have been moved: always.sys dtc329x.sys t128.sys t13b.sys tmv1.sys ultra124.sys wd33c93.sys The following adapters are affected by this change: SCSI ADAPTERS Always IN-2000 (always.sys) Data Technology Corp. 3290 (dtc329x.sys) Maynard 16-bit SCSI Adapter (wd33c93.sys) MediaVision Pro Audio Spectrum-16 (tmv1.sys) Trantor T-128 (t128.sys) Trantor T-130B (t13b.sys) DISK CONTROLLERS UltraStor 124f EISA Disk Array Controller (ultra124.sys) Please see the Windows NT Hardware Compatibility List for additional information on these storage adapters. To create a driver disk for drivers that have been moved to the Driver Library 1. Create a blank formatted 3.5-inch disk. 2. Copy all files from the following directory to the blank disk: \drvlib\storage\retired\CPU_TYPE Where CPU_TYPE is X86 if you are using a machine with an x86-based processor; MIPS if your computer uses a MIPS RISC processor; or ALPHA if your computer uses a Digital Alpha processor. 3. Label this disk Drivers disk. To install drivers from your drivers disk during Windows NT version 4.0 Setup 1. Start Windows NT Setup. During the course of Setup, a message appears stating "Setup has recognized the following mass storage devices in your computer." 2. Press S to display a list of supported SCSI host adapters. 3. Select Other from the bottom of the list. 4. Insert your Drivers disk when prompted to do so, and select your host adapter from this list. Windows NT will now recognize any devices attached to this adapter. Repeat this step for each host adapter not already recognized by Windows NT Setup. To install drivers when Setup recognizes one of the supported SCSI host adapters without making the devices attached to it available for use 1. Restart Windows NT Setup. 2. When Windows NT Setup displays the message "Setup is inspecting your computer's hardware configuration...," press F6. This prevents Windows NT Setup from performing disk controller detection and allows you to install the driver from the Drivers disk you created. Note that all SCSI adapters will have to be installed manually. 3. When Windows NT Setup displays the message "Setup could not determine the type of one or more mass storage devices installed in your system, or you have chosen to manually specify an adapter," press S to display a list of supported SCSI host adapters. 4. Select Other from the bottom of the list. 5. Insert the Drivers disk you made when prompted to do so, and select your host adapter from this list. Note that in some cases, Windows NT Setup will repeatedly prompt you to swap disks. Windows NT will now recognize any devices attached to this adapter. Repeat this step for each host adapter not already recognized by Windows NT Setup. To install drivers from your drivers disk after running Windows NT version 4.0 Setup 1. After installing the properly configured adapter in your machine, boot into Windows NT version 4.0 as normal. 2. From the Start button, open Control Panels, then open the SCSI Adapters program. 3. Select the Drivers tab, then click the Add button. 4. Click the Have Disk button, insert your drivers disk into Drive A: and click OK. 5. Highlight the desired driver from the list presented and click OK, then click Continue to load the driver. 6. You need to reboot your Windows NT version 4.0 system to activate the driver. Click the Restart Computer button to shutdown and restart.
