Installing Windows NT and its device drivers - ThinkPad X20, X21

This section describes the procedures for installing Microsoft Windows NT Workstation Version 4.0 and its device drivers.

Overall procedure

NOTES:

  • If you are installing Windows NT onto a hard disk drive whose capacity is 8GB or larger, refer to the Microsoft Web site for support article number Q197667, and copy the IDE driver (Atapi.sys) to the hard disk before starting installation.
  • If you want to reinstall Windows NT onto the hard disk that has been used for Windows 2000, Windows 98 or Windows 95, the Windows NT installation program might not recognize the partitions generated by the Windows 2000, Windows 98 or Windows 95 Fdisk Utility. Use the PC-DOS Fdisk Utility instead.
  1. Have the Windows NT installation package available.
  2. Back up your software and personal data files on the hard disk.
  3. Install Windows NT according to the instructions provided with the installation package.
  4. Install Windows NT Version 4 Service Pack 6.
  5. Insert the Software Selections CD into the CD-ROM drive. The Software Selections program main window appears.
  6. Click Install Software.
  7. Click the View All button above the Program Name list window. A list of all the device drivers and other programs in the Software Selections CD appears.
  8. Mark the check box for each device driver and program that you want to install. You can select multiple device drivers and programs at a time.
  9. Click the Install button at the bottom right of the window, and follow the instructions on the screen.

If you are restoring your ThinkPad computer to its original state at the time of purchase, you need to install at least the following device drivers:

Installing Microsoft Windows NT

  1. Before installing Windows NT, read the Windows NT installation guide.
  2. To install Windows NT using an external CD-ROM drive, do the following.

NOTE: If you have an external CD-ROM drive that connects under a DOS environment, you can install Windows NT in DOS.

  1. Insert the Windows NT CD into the external CD-ROM drive.
  2. Open a directory for the CD; then go to the \I386 directory.
    For example, if your CD-ROM drive letter is D, go to D:\I386
  3. At the command prompt, type WINNT and then press Enter.
    For example, D:\I386>WINNT
  4. Follow the instructions on the screen.

If your computer does not have a CD-ROM drive, you can use a network server. You can install Windows NT on multiple computers by first copying the Windows NT master source files to a shared drive on a network server. After connecting your computer to a network, such as with the DOS LAN requester, you can install the files from the network server to your computer at the DOS command prompt.

For more information, refer to the installation guide of Windows NT, Windows NT Version 4 Service Pack 3, Windows NT Version 4 Service Pack 4, or Windows NT Version 4 Service Pack 5.

Installing PC Card support software
You should install Service Pack 4 or Service Pack 5 before you install the PC Card support software. If you have already installed Service Pack 4, you need to reinstall the PC Card support software.

If you are going to use a docking station or port replicator with your computer, do the following:

  1. If your computer is connected to a network, log off before starting the installation.
  2. Uninstall the support software for the PC Card (CardWizard).
  3. Dock your computer to the docking station or port replicator.
  4. If you want to install the Windows NT Service Pack, install it before you install the support software for the PC Card.
  5. Reinstall the support software for the PC Card.
