NOTES for MS-DOS 6.2 Step-Up Users
The MS-DOS 6.2 Step-Up includes all the files you need to update your
system from MS-DOS 6 to MS-DOS 6.2.
IMPORTANT: To use the MS-DOS 6.2 Step-Up, you must be running the
released version of MS-DOS 6. If you are running an older
version of MS-DOS, a beta version of MS-DOS 6, or any
version of MS-DOS that was modified by a hardware vendor,
you cannot use the MS-DOS 6.2 Step-Up. To install MS-DOS
6.2 on such a system, obtain the full MS-DOS 6.2 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 disks.
This file contains the following topics:
• What MS-DOS 6.2 Step-Up includes
• Installing MS-DOS 6.2

1. What MS-DOS 6.2 Step-Up Includes
The MS-DOS 6.2 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 disk(s)
simply specify changes for MS-DOS 6.2 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 6.2. To do this, Setup must be
able to find and update each of your MS-DOS 6 files.
2. Installing MS-DOS 6.2
This section explains how to update your system to MS-DOS 6.2.
Note: If you did not install the MS-DOS 6 optional programs
(Backup, AntiVirus and Undelete), then MS-DOS 6.2 Setup
cannot update those programs to version 6.2. If you want the
MS-DOS 6.2 versions of these programs, carry out the procedure
in Section 3 of this file before installing MS-DOS 6.2.
2.1 Running Setup
To update your system to MS-DOS 6.2, your computer must already
be running MS-DOS 6. For Setup to work properly, your MS-DOS 6 files
must be located on drive C; if your MS-DOS 6 files are on a drive other
than drive C, follow the procedure in section 2.2.
To install MS-DOS 6.2, follow these steps:
• If Windows is running, quit Windows.
• At the command prompt, type VER to ensure that you are running
the release version of MS-DOS 6.0.
• Insert MS-DOS 6.2 Setup Disk 1 in drive A or drive B.
• Type A:SETUP or B:SETUP.
2.2 Running Setup if your MS-DOS 6 files are not located on drive C
The MS-DOS 6.2 Step-Up is designed to update MS-DOS 6 files
that are located on drive C. If your MS-DOS 6 files are located
on a drive other than C, follow these steps:
• Create a new directory on drive C (for example, C:\DOS).
• Copy your MS-DOS 6 files to that directory. For example, if your
MS-DOS 6 files are located in the D:\DOS directory and you
want to copy them to the C:\DOS directory, you would type:
• Insert MS-DOS 6.2 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 MS-DOS 6 files, type the pathname of the directory you just
created on drive C (for example, C:\DOS).
• When Setup is complete, MS-DOS 6.2 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 6.2 files.
If you want to move MS-DOS 6.2 back to the other drive, copy all
the MS-DOS 6.2 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
6.2 installation is incomplete because the specified file was not
updated to version 6.2. 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.
• 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.
• 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.
• Run MS-DOS 6.2 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 6.2 disks. You may be able to
correct the problem by running SCANDISK or CHKDSK /F on the MS-DOS 6.2
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 6.2 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 disks.
• You are running a version of MS-DOS 6 in a language that is
different from the version of MS-DOS 6.2 you aretrying to
install. If this is the problem, obtain the MS-DOS 6.2 Step-Up for
the same language as your current version of MS-DOS 6.
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 6.2 Setup automatically updates the Backup, Undelete and
Antivirus programs only if the MS-DOS 6 versions of these programs are
already on your computer when you run MS-DOS 6.2 Setup. If you want the
MS-DOS 6.2 versions of these programs, but the MS-DOS 6 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 6.2 yet).
3.1 If you have not yet installed MS-DOS 6.2
The easiest way to install the MS-DOS 6.2 versions of Backup, Undelete
and Antivirus is to install the MS-DOS 6 versions of those programs
before you run MS-DOS 6.2 Setup. Follow these steps:
• Insert MS-DOS 6 Setup Disk 1 in drive A or drive B.
• Type A:SETUP /E or B:SETUP /E at the command prompt, and then
follow the instructions on your screen.
• Run MS-DOS 6.2 Setup as described in Section 2 of this file.
3.2 If you have already installed MS-DOS 6.2
If Backup, Undelete, or Antivirus were not on your system when you
installed MS-DOS 6.2, but you later decided that you want the
MS-DOS 6.2 versions of those programs, carry out one of the following
procedures (depending on whether your MS-DOS 6 disks fit in drive A).
Procedure 1: Updating the optional programs if your MS-DOS 6 disks fit in drive A
If your MS-DOS 6 disks fit in drive A, follow these steps:
• Insert MS-DOS 6 Setup Disk 1 in drive A, and restart your computer.
(If your MS-DOS 6 disks do not fit in drive A, carry out procedure 2
instead.)
• The Welcome screen for MS-DOS 6 Setup appears. Press the F3 key
twice to exit.
• Use the PATH command to ensure that your current search path
includes the directory that contains your MS-DOS 6.2 files. For
example, if your MS-DOS 6.2 files are in C:\DOS, you would type
Note: Be sure to specify the drive letter in uppercase.
• Change to the drive that contains MS-DOS 6 Setup Disk 1, and then
run MS-DOS 6 Setup by typing the following:
Select the optional programs you want. When MS-DOS Setup is
complete, remove MS-DOS 6 Setup Disk 1 and restart your computer.
• Run MS-DOS 6.2 Setup as described in Section 2 of this file.
Procedure 2: Updating the optional programs if your MS-DOS 6 disks don't fit in drive A
If your MS-DOS 6 disks don't fit in drive A, follow these steps:
• Create an MS-DOS 6 startup floppy disk by inserting your MS-DOS 6
Setup Disk 1 in drive B and typing the following:
• When Setup displays the settings it will use, the "Install
on Drive:" setting will specify drive B. Change this setting
to drive A.
Setup then creates a startup floppy disk. To complete Setup,
follow the instructions on your screen.
• Restart your computer from the MS-DOS 6 startup floppy disk you
just created (leave the disk in drive A, and press CTRL+ALT+DEL).
• Use the PATH command to ensure that your current search path
includes the directory that contains your MS-DOS 6.2 files. For
example, if your MS-DOS 6.2 files are in C:\DOS, you would type
Note: Be sure to specify the drive letter in uppercase.
• Change to the drive that contains MS-DOS 6 Setup Disk 1, and then
type the following to install the optional MS-DOS 6 programs:
Select the optional programs you want. When MS-DOS Setup is
complete, remove MS-DOS 6 Setup Disk 1 and restart your computer.
• Run MS-DOS 6.2 Setup as described in Section 2 of this file.
4. Reading the README.TXT file on Setup Disk 1
After you install MS-DOS 6.2, a copy of the README.TXT file will be
located in the directory that contains your MS-DOS 6.2 files. To read
this file, change to that directory, and then type the following
at the command prompt:
If you need to, you can read the copy of README.TXT located on
Setup Disk 1. To do this:
• 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.
• 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.
