Disks Created by MS-DOS 6 Upgrade Using Setup /F

This chapter describes some tips you can use during or just after Setup. It also describes how to set up MS-DOS 6 Upgrade over DR-DOS.

You can create a single startup floppy disk for drive A by specifying the setup command with the /f switch. The contents of the startup floppy disk will vary based on the disk's capacity.

Note: You cannot use MS-DOS 6 Upgrade to install the complete operating system (with all programs) to floppy disks.

The following files will be copied to a floppy disk if you specify the setup /f command:

Installing Windows-Based Utilities on Computers That Do Not Have Windows

Setup does not install the Windows-based Backup, Anti-Virus, or Undelete utilities if it does not find a Microsoft Windows™ operating system installation, because it cannot update your SYSTEM.INI or WIN.INI files. After you install Windows, you can install the optional components for Windows by using the setup command with the /e switch.

How Upgrade Setup Alters Your Windows Configuration

Depending on the programs you select, Setup makes some changes to your Windows PROGMAN.INI and SYSTEM.INI files.

Changes to PROGMAN.INI

Setup adds a new Program Manager group by adding a line to your PROGMAN.INI file. The .GRP (group) file contains the program items for the programs you selected (Microsoft Anti-Virus, Backup, or Undelete).

For example, if your MS-DOS files are in C:\DOS, Setup might add the following line to your PROGMAN.INI file:

group11=c:\dos\wntools.grp

Changes to SYSTEM.INI

If necessary, Setup adds a command for the VFINTD.386 driver to the [386Enh] section of your SYSTEM.INI file. VFINTD.386 is a virtual device driver that allows Microsoft Backup for Windows to gain exclusive access to your floppy drives. This driver is needed only for Backup support.

For example, if your MS-DOS files are in C:\DOS, Setup might add the following lines to the [386Enh] section of your PROGMAN.INI file:

;======== MS-DOS 6 Setup Modification - Begin ========
device=c:\dos\vfintd.386
;======== MS-DOS 6 Setup Modification - End ========

How to Install MS-DOS 6 Upgrade over DR-DOS

The MS-DOS 6 Upgrade Setup program detects the following DR-DOS configurations:

• Delwatch

• Password-protected partitions

• DR compression

• Invalid CONFIG.SYS commands

In the first three cases, Setup points you to the README.TXT file. If Setup detects invalid CONFIG.SYS commands, you can choose to keep your original CONFIG.SYS file or let Setup modify it.

Setup Detects That Your Computer Uses DR-DOS

If you have DR-DOS installed on your computer, you should take the following precautions before restarting Setup:

• If you have any security features, including password protected partitions, you should disable them. For more information, see "Setup displays the 'Your computer uses password protection' screen" in the chapter "Diagnosing and Solving Problems" in the MS-DOS 6 User's Guide.

  Warning: MS-DOS 6 Upgrade cannot detect DR-DOS files or directories that are password protected. Since Setup cannot see these directories, it fails by returning you to the C prompt.

• If you have Delwatch installed on your computer, carry out the procedure "Setup displays the 'Your computer is using an incompatible delete-protection program' screen" in the chapter "Diagnosing and Solving Problems" in the MS-DOS 6 User's Guide.

• If your CONFIG.SYS or AUTOEXEC.BAT files use any conditional commands, such as the ? or goto commands, you should remove them and adjust the order of commands in your startup files accordingly.

• If your CONFIG.SYS uses the chain command, you should remove it and adjust the order of commands in this file accordingly.

• If your computer uses disk-compression but drive C is not compressed, run Setup as described in the section "Getting Started" in the MS-DOS 6 User's Guide. When Setup displays the message "Your CONFIG.SYS file contains commands that are not valid MS-DOS commands," choose the "Modify original files" option.

• If drive C is compressed, carry out the following procedure.

  To install MS-DOS 6 if drive C is compressed

  1. Determine which drive is your original uncompressed drive. For more information, see your DR-DOS documentation.

  2. Make backup copies of your CONFIG.SYS and AUTOEXEC.BAT files on your compressed drive, and your DCONFIG.SYS file on your uncompressed drive.

  3. Combine the two configuration files.

     For example, if drive D is your uncompressed drive, type the following at the command prompt:

copy d:\dconfig.sys+c:\config.sys d:\config.sys

4.  Copy the combined CONFIG.SYS file to drive C.
    
    For example, if drive D is your uncompressed drive, type the following at the command prompt:
    
    <pre IsFakePre="true" xmlns="https://www.w3.org/1999/xhtml">

copy d:\config.sys c:\config.sys

5.  Copy your AUTOEXEC.BAT to your uncompressed drive.
    
    For example, if drive D is your uncompressed drive, type the following at the command prompt:
    
    <pre IsFakePre="true" xmlns="https://www.w3.org/1999/xhtml">

copy c:\autoexec.bat d:\autoexec.bat

6.  Insert Setup Disk 1 in drive A or B, and type the following at the command prompt:
    
    <pre IsFakePre="true" xmlns="https://www.w3.org/1999/xhtml">

a:setup

    or
    
    <pre IsFakePre="true" xmlns="https://www.w3.org/1999/xhtml">

b:setup

7.  When Setup displays the "Your CONFIG.SYS file contains commands that are not valid MS-DOS commands" message, choose the "Modify original files" option.

8.  After Setup is complete, MS-DOS will display an "Unrecognized command" message on your screen for each command in your AUTOEXEC.BAT and CONFIG.SYS files that is not a valid MS-DOS command. Remove these commands from your CONFIG.SYS and AUTOEXEC.BAT files.

9.  Add a command that starts the Himem memory manager to your CONFIG.SYS file. For example, if C:\\DOS contains your MS-DOS files, add the following line to the beginning of your CONFIG.SYS file:
    
    <pre IsFakePre="true" xmlns="https://www.w3.org/1999/xhtml">

device=c:\dos\himem.sys
