Notes for MS-DOS 6.22 Step-Up Users
===================================
The MS-DOS 6.22 Step-Up includes all the files you need to update your
system from MS-DOS 6, MS-DOS 6.2 or MS-DOS 6.21 to MS-DOS 6.22.

IMPORTANT: To use the MS-DOS 6.22 Step-Up, you must be running the
	   released version of MS-DOS 6, 6.2, or 6.21. If you are 
	   running an older version of MS-DOS, a beta version of 
	   MS-DOS, or any version of MS-DOS that was modified by a 
	   hardware vendor, you cannot use the MS-DOS 6.22 Step-Up. 
	   To install MS-DOS 6.22 on such a system, obtain the 
	   full MS-DOS 6.22 Upgrade product.

This file contains information specific to the Step-Up installation process. 
If you don't find the information you need in this file, see the README.TXT 
file, which is located in the directory that contains your MS-DOS files
or on Setup Disk 1 of your MS-DOS 6.0, 6.2 or 6.21 disks.

1. What MS-DOS 6.22 Step-Up Includes
====================================
The MS-DOS 6.22 Step-Up includes all changes that were made to the
MS-DOS files since MS-DOS 6. Most of the files on the Step-Up disks
simply specify changes and are not complete programs. When you run 
Setup, it modifies the MS-DOS files on your hard disk to incorporate 
the changes for MS-DOS 6.22. To do this, Setup must be able to 
find and update each of your MS-DOS 6 or MS-DOS 6.2 files.


2. Installing MS-DOS 6.22
=========================
This section explains how to update your system to MS-DOS 6.22.

Note:  If you did not install MS-DOS optional programs 
       (Backup, AntiVirus and Undelete), then MS-DOS 6.22 Setup 
       cannot update those programs. If you want the latest versions 
       of these programs, carry out the procedure in Section 3 of this 
       file before installing MS-DOS 6.22.

2.1  Running Setup
------------------
To update your system to MS-DOS 6.22, your computer must already
be running MS-DOS 6 or MS-DOS 6.2. For Setup to work properly, your 
MS-DOS 6 or 6.2 files must be located on drive C; if these files 
are on a drive other than drive C, follow the procedure in section 2.2.

To install MS-DOS 6.22, follow these steps:

1. If Windows is running, quit Windows.

2. At the command prompt, type VER to ensure that you are running
   the release version of MS-DOS 6.0 or MS-DOS 6.2.

3. Insert MS-DOS 6.22 Setup Disk 1 in drive A or drive B.

4. Type A:SETUP or B:SETUP.


2.2  Running Setup if your MS-DOS files are not located on drive C
------------------------------------------------------------------
The MS-DOS 6.22 Step-Up is designed to update MS-DOS files 
that are located on drive C. If your MS-DOS files are located 
on a drive other than C, follow these steps: 

1. Create a new directory on drive C (for example, C:\DOS).

2. Copy your current MS-DOS files to that directory. 

   For example, if your MS-DOS files are located in the D:\DOS 
   directory and you want to copy them to the C:\DOS directory, 
   you would type:

   COPY D:\DOS\*.* C:\DOS

3. Insert MS-DOS 6.22 Setup Disk 1 in drive A or drive B, and then type
   A:SETUP or B:SETUP. When Setup displays the directory that contains
   your current MS-DOS files, type the pathname of the directory you just 
   created on drive C (for example, C:\DOS).

4. When Setup is complete, MS-DOS 6.22 will be installed on drive C.
   Setup updates the pathnames in your CONFIG.SYS and AUTOEXEC.BAT
   files so that they refer to the directory on drive C that contains
   your MS-DOS 6.22 files. 
   
   If you want to move MS-DOS 6.22 back to the other drive, copy all 
   the MS-DOS 6.22 files to a directory on the other drive. You will 
   also need to correct the pathnames in your CONFIG.SYS and AUTOEXEC.BAT 
   files to refer to the correct drive and directory.


2.3  If Setup cannot update a file
----------------------------------
If Setup cannot update one of your MS-DOS files, it displays a message
with the title "Cannot Update File." If you continued Setup, your MS-DOS 
6.22 installation is incomplete because the specified file was not updated
to version 6.22. If the file is one you know you don't need, don't 
worry about it. However, if you are not sure, update the file using the 
following procedure.

Note:  This procedure assumes that you are upgrading from MS-DOS 6. 
       If you are upgrading from MS-DOS 6.2, use your MS-DOS 6.2 disks
       instead. (Use your MS-DOS 6 disks if you are upgrading from 
       MS-DOS 6.2, but installed MS-DOS 6.2 using the MS-DOS 6.2 Step-Up.)

1. Insert MS-DOS 6 Setup Disk 1 in drive A or drive B, and then use
   MS-DOS Editor (EDIT) to view the contents of the PACKING.LST file.
   This file tells you where each file is located on your MS-DOS 6 disks.
   Determine which MS-DOS 6 disk contains the file you need. 

2. Insert the appropriate MS-DOS 6 disk in drive A or drive B, and then
   use the EXPAND command to expand the file. For example, to expand the
   file DBLSPACE.HL_ from the disk in drive A to the directory C:\DOS, 
   you would type the following  command:
   
	EXPAND A:\DBLSPACE.HL_ C:\DOS\DBLSPACE.HLP

   For more information, see the comments at the beginning of the PACKING.LST
   file, or see the MS-DOS 6 User's Guide.

3. Run MS-DOS 6.22 Setup again. This time, Setup should be able to update the
   file. 
   
If you follow this procedure and Setup still cannot update the file, there 
may be a problem with your MS-DOS 6.22 disks. You may be able to correct 
the problem by running SCANDISK or CHKDSK /F on the MS-DOS 6.22 disk that 
was in the drive when the error occurred. 


2.4  If Setup cannot find the correct IO.SYS file
-------------------------------------------------
If Setup cannot find the correct IO.SYS file, one of the following may
be the cause of the problem:

  * You are not running a released version of MS-DOS 6 or 6.2.
    To use the MS-DOS 6.22 Step-Up, you must be running the released
    version of MS-DOS 6 or 6.2. The Step-Up will not work on other
    versions of MS-DOS, on other manufacturers' operating systems, or
    on beta versions of MS-DOS. 

  * Your IO.SYS file has been damaged or modified. Setup cannot update 
    an IO.SYS file that has been corrupted (for example, by a virus or
    a hard disk error) or an IO.SYS file that has been modified by another
    program (such as an MS-DOS extender). If you suspect this is the problem,
    use the SYS command to copy the system files from Setup Disk 1 of
    your MS-DOS 6 or 6.2 disks.

  * You are running a version of MS-DOS in a language that is different
    from the version of MS-DOS 6.22 you are trying to install. If this 
    is the problem, obtain the MS-DOS 6.22 Step-Up for the same language 
    as your current version of MS-DOS.

Note: The IO.SYS file is a file with the hidden, read-only and system 
      attributes. It is normally located in the root directory of your 
      startup drive.


3. Updating Microsoft Backup, Undelete and Antivirus
====================================================
MS-DOS 6.22 Setup automatically updates the Backup, Undelete and Antivirus
programs only if the MS-DOS 6 or 6.2 versions of these programs are already 
on your computer when you run MS-DOS 6.22 Setup. (These programs have not
changed since MS-DOS version 6.2.) If you want the latest versions 
of these programs, but the MS-DOS 6 or 6.2 versions are not currently
installed on your system, carry the procedure in section 3.1 or 3.2
(depending on whether you have installed MS-DOS 6.22 yet).


3.1 If you have not yet installed MS-DOS 6.22
---------------------------------------------
The easiest way to install the latest versions of Backup, Undelete
and Antivirus is to install the MS-DOS 6 or 6.2 versions of those programs
before you run MS-DOS 6.22 Setup. Follow these steps:

1. Insert MS-DOS 6 or 6.2 Setup Disk 1 in drive A or drive B.

2. Type A:SETUP /E or B:SETUP /E at the command prompt, and then
   follow the instructions on your screen.

3. Run MS-DOS 6.22 Setup as described in Section 2 of this file.


3.2  If you have already installed MS-DOS 6.22
----------------------------------------------
If Backup, Undelete, or Antivirus were not on your system when you 
installed MS-DOS 6.22, but you later decided that you want the 
latest versions of those programs, carry out one of the following 
procedures (depending on whether your MS-DOS 6 or 6.2 disks fit in drive A).


Procedure 1: Updating the optional programs if your MS-DOS 6 or 6.2 
	     disks fit in drive A
-------------------------------------------------------------------
If your MS-DOS 6 or 6.2 disks fit in drive A, follow these steps:

1. Insert MS-DOS 6 or 6.2 Setup Disk 1 in drive A, and restart your computer.
   (If your MS-DOS disks do not fit in drive A, carry out procedure 2
   instead.)

2. The Welcome screen for MS-DOS Setup appears. Press the F3 key
   twice to exit.

3. Use the PATH command to ensure that your current search path includes
   the directory that contains your MS-DOS 6.22 files. For example, if
   your MS-DOS 6.22 files are in C:\DOS, you would type

      PATH C:\DOS

   Note: Be sure to specify the drive letter in uppercase.

4. Type the following at the command prompt:

      A:SETUP /E

   Select the optional programs you want. When MS-DOS Setup is complete,
   remove MS-DOS 6 or 6.2 Setup Disk 1 and restart your computer.

5. Run MS-DOS 6.22 Setup as described in Section 2 of this file.


Procedure 2: Updating the optional programs if your MS-DOS 6 or 6.2 
	     disks don't fit in drive A
-------------------------------------------------------------------
If your MS-DOS 6 or 6.2 disks don't fit in drive A, follow these steps:

1. Create an MS-DOS 6 or 6.2 startup floppy disk by inserting your 
   MS-DOS 6 or 6.2 Setup Disk 1 in drive B and typing the following:

	B:SETUP /F

2. When Setup displays the settings it will use, the "Install
   on Drive:" setting will specify drive B. Change this setting
   to drive A, and insert a blank formatted floppy disk in drive A.

   Setup then creates a startup floppy disk. To complete Setup,
   follow the instructions on your screen.

3. Restart your computer from the startup floppy disk you just
   created (leave the disk in drive A, and press CTRL+ALT+DEL).

4. Use the PATH command to ensure that your current search path includes
   the directory that contains your MS-DOS 6.22 files. For example, if
   your MS-DOS 6.22 files are in C:\DOS, you would type

      PATH C:\DOS

   Note: Be sure to specify the drive letter in uppercase.

5. Change to the drive that contains MS-DOS 6 or 6.2 Setup Disk 1, and 
   then type the following to install the optional programs:

      SETUP /E

   Select the optional programs you want. When MS-DOS Setup is complete,
   remove MS-DOS 6 or 6.2 Setup Disk 1 and restart your computer.

6. Run MS-DOS 6.22 Setup as described in Section 2 of this file.


4. Reading the README.TXT file on Setup Disk 1
==============================================
After you install MS-DOS 6.22, a copy of the README.TXT file will be
located in the directory that contains your MS-DOS 6.22 files. To read
this file, change to that directory, and then type the following
at the command prompt:

   EDIT README.TXT

If you need to, you can read the copy of README.TXT located on
Setup Disk 1. To do this:

1. Insert Setup Disk 1 in a floppy disk drive, and then make 
   that drive your current drive. For example, if the disk is
   in drive A, type A: at the command prompt.

2. At the command prompt, type the following command:

   EXPAND README.TX_ C:\README.TXT

You should then be able to use the EDIT command to view the 
C:\README.TXT file.
