1.0  Introduction
-----------------
This release of Microsoft(R) Windows NT(TM) 3.51 U.S. Service Pack 1 is
easy to apply from within Windows NT and changes only those files that
were originally set up on the Windows NT Workstation or Windows NT Server
system.  Service Pack releases are cumulative: they contain all previous
fixes, as well as any new fixes made to the system.


2.0  Installation Instructions for the Windows NT U.S. Service Pack
-------------------------------------------------------------------
Installing the Service Pack from a floppy disk:
1.  Insert Service Pack Disk 1 into the floppy drive.
2.  At the Windows NT Command Prompt, change to that floppy drive (that is,
    A: or B:) and type UPDATE.
3.  Follow the instructions given on the screen.

Installing the Service Pack from a CD-ROM:
1.  Insert the Service Pack CD-ROM disk into the CD-ROM drive.
2.  At the Windows NT Command Prompt, change to that CD-ROM drive, then
    change to the i386, MIPS, or ALPHA directory (depending upon whether
    you have an Intel(TM), MIPS(R), or ALPHA AXP(TM) CPU), and type UPDATE.
3.  Follow the instructions given on the screen.

Installing the Service Pack from a network drive:
1.  At the Windows NT Command Prompt, type the command to connect to the
    network drive on which the Service Pack files reside.
2.  Change to that network drive and type UPDATE.
3.  Follow the instructions given on the screen.


2.1  User Notes
---------------
*** Emergency Repair Disk

If it is necessary to use the Windows NT Emergency Repair Disk to repair
your Windows NT system at some time after you apply the Service Pack, you
will need to re-apply the Service Pack after the repair is completed.  This
is because the Emergency Repair Disk repairs your system by restoring your
original Windows NT setup.  After the repair has completed, simply follow
the above Installation Instructions to reapply the Service Pack.


*** Adding New Components to the System

If new software or hardware components are changed or added to your system
after you have applied the Service Pack, it will be necessary to reapply
the Service Pack.  This is because the files taken from the original
Windows NT disk set may not be equivalent to the files on the Service Pack
disk set.  It is not possible to install new components directly from the 
Service Pack media (such as a new keyboard or printer driver).  New 
components must be installed from the original product media.


*** Installing Symbol Files from the CD-ROM

To install the symbol files corresponding to the new binaries in Service
Pack 1, do the following (assuming your CD-ROM drive is D:, your symbol
files are located in the C:\WINNT\SYMBOLS directory, and you are installing
the files for an x86 machine):

    XCOPY /S /U /D D:\SUPPORT\DEBUG\I386\SYMBOLS C:\WINNT\SYMBOLS

This will copy the Service Pack 1 .DBG files over the existing versions of
these files.  The XCOPY command shown will copy only those .DBG files that
are already installed (/U switch), and only those with a more recent time-
date stamp (/D switch).
