This soft copy for use by IBM employees only.

3.1.2.3 Unsupported Hardware

NT 4.0 does not currently support the following controller and BIOS enhancements:

•

•

•

•

•

32-bit I/O BIOS switch Enhanced drive access

Multiple block addressing or rapid IDE Write-back cache on disk controllers Power management features

3.2 Setup Options

There are three options you can use to install NT 4.0 that are supported by

Microsoft:

1. Standard Setup

Installing directly from the CD-ROM as described in Chapter 5, ªInstalling Windows NT Server 4.0º on page 81 or from diskettes is almost always the best method of setting up your Windows NT system. It offers the best support for alternate Hardware Abstraction Layers (HALs), timing and third-party drivers. If you have a supported CD-ROM drive, you should choose this setup method. This installation method requires a minimum of 124 MB of free space.

This is the method we recommend for use with IBM PC Servers.

Creating Boot Diskettes?

If you misplace the setup disks for the standard setup, run either WINNT /OX or WINNT32 /OX from the I386 directory on the installation CD-ROM to create new boot disks for a standard setup.

You can also ServerGuide to build these diskettes. Refer to 4.3.2, ªAutoPilotº on page 76for more information.

2.WINNT or WINNT32 Setup

This method was designed for network installations or for computers with unsupported CD-ROM drives. It builds the boot disks and performs a file copy of the setup directory to the hard disk drive before the setup procedure begins. It is the second best choice after the standard setup. This installation method also requires a minimum of 124 MB of free space.

See 3.2.2, ªThe WINNT Commandº on page 64 for more information on the WINNT command.

3.Installing over a Network

For networks where the Windows NT installation files are kept on a central server, network installations can be accomplished using the WINNT command or by copying the entire I386 directory from the setup CD-ROM to the hard disk drive and then running WINNT from the local disk drive. This can reduce network traffic and dependency. The stability of your network can have a detrimental impact on your installation process when installing across the network. One of the more common problems is that the NetBIOS protocol time-outs are set incorrectly. This will cause the installation process to fail, especially if the server you are installing from is busy. If you copying the entire I386 directory from the CD-ROM to the hard disk you will need 223 MB of free space.
