DISK MANAGER AUGUST 3, 1995 Windows NT 3.1 ................................... 1 Windows NT 3.5 .................................... 1 Windows NT 3.51 ................................... 4 WINDOWS NT 3.1 Windows NT 3.1 no support provided. WINDOWS NT 3.5 The following information applies to systems with drives installed using the Dynamic Drive Overlay. No special steps are required if the Dynamic Drive Overlay was not required for your installation. Drives that are using the Dynamic Drive Overlay must be larger than 528MB and have 63 sectors per track. If you are using an IDE CD-ROM, it must be connected to a secondary controller and your IDE hard drive(s) connected to a primary controller. To install the updated driver on an existing Windows NT 3.5 system: If you are adding a drive to an existing system already running Windows NT 3.5, replace the ATDISK.SYS driver in the \WINNT\SYSTEM32\DRIVERS subdirectory with the one provided on the Disk Manager diskette. There are three ways to install Windows NT 3.5 on a drive installed by Disk Manager. To install Window NT 3.5 from diskette or CD-ROM: To perform this installation you must install Windows NT on a FAT partition since you need to be able to access it from DOS. 1) Make a diskcopy of Setup Disk #3. 2) Replace ATDISK.SYS on the diskcopy of Setup Disk #3 with the updated ATDISK.SYS provided on the Disk Manager diskette. 3) Boot the system from the hard drive. As soon as the Dynamic Overlay banner appears press the SPACEBAR. Insert Setup Disk #1 and press the SPACEBAR to boot from it. 4) When the first phase of SETUP is complete you will be prompted to reboot. Do so. As soon as the Dynamic Drive Overlay banner appears press the SPACEBAR. Insert your DOS boot diskette and press the SPACEBAR to boot from it. 5) Replace ATDISK.SYS in the \WINNT35\SYSTEM32\DRIVERS subdirectory on the hard drive with the updated ATDISK.SYS provided on the Disk Manager diskette. 6) Reboot the system and complete the installation as directed by SETUP. DO NOT CONVERT YOUR SYSTEM PARTITION TO NTFS! See the notes below on using the Windows NT 3.5 Emergency Repair option. To install Windows NT 3.5 from DOS using WINNT.EXE: To perform this installation you must install Windows NT on a FAT partition since you need to be able to access it from DOS during the installation. You must have DOS access to the CD-ROM or a network directory containing the Windows NT 3.5 master files to perform this procedure. This process requires about 50MB of extra disk space. 1) Boot the system from the hard drive. If you need to boot to a diskette, press the SPACEBAR as soon as the Dynamic Drive Overlay banner appears. Insert a DOS boot diskette and press the SPACEBAR to boot from it. 2) Change to the \I386 directory on the CD-ROM or the network directory in which the Windows NT 3.5 master files are installed. 3) Run WINNT /B. This option will load Windows NT Setup to create temporary directories, $WIN_NT$.~LS and $WIN-NT$.~BT, on your hard drive and copy the necessary files to them. 4) After the file copy is finished you will be prompted to reboot. Do so. As soon as the Dynamic Drive Overlay appears press the SPACEBAR. Insert a DOS boot diskette and press the SPACEBAR to boot from it. 5) Replace the file ATDISK.SYS in the directories $WIN-NT$.~LS and $WIN-NT$.~BT with the updated ATDISK.SYS provided on the Disk Manager diskette. 6) Reboot the system and complete the installation as directed by SETUP. DO NOT CONVERT YOUR SYSTEM PARTITION TO NTFS! See the notes below on using the Windows NT Emergency Repair option. Windows NT 3.5 Emergency Repair option. If you have converted your Windows NT system partition to NTFS,DO NOT allow the Windows NT 3.5 Emergency Repair option to replace the updated ATDISK.SYS (see step 2 below). If this occurs or if that file is corrupted, you will need to reinstall Windows NT since you can no longer replace the file from DOS. If you installed Windows NT 3.5 using the updated ATDISK.SYS and need to use the Windows NT Emergency Repair option to correct problems, you must follow the guidelines below. 1) When you boot to the Windows NT Setup Disks to run the Emergency Repair, be sure you use the Setup Disk #3 with the updated ATDISK.SYS provided in the NT directory of the Disk Manager diskette. If you no longer have the modified Setup Disk #3 used to install the system, you will need to make one. 2) If you allow the Emergency Repair option to check and replace system files, it will detect that the ATDISK.SYS file has been changed and offer to replace it with the original. Do not replace this file. Replacing the file is of no value since your system requires the updated ATDISK.SYS. 3) When the Emergency Repair is complete you should manually replace the updated ATDISK.SYS file (in case it has been replaced or corrupted). Follow these steps to do so: - Reboot the system from the hard drive. As soon as the Dynamic Drive Overlay banner appears press the SPACEBAR. Insert a DOS boot diskette and press the SPACEBAR to boot from it. - Replace ATDISK.SYS in the \WINNT35\SYSTEM32\DRIVERS subdirectory on the hard drive with the updated ATDISK.SYS provided on the Disk Manager diskette. - Reboot the system. Windows NT should now load.
