This chapter explains how to upgrade your existing version of SoftWindows, and lists the files installed by the installation process.
Your SoftWindows is automatically updated when you run the new version of SoftWindows. If you are running Novell NetWare, you may also need to upgrade Novell Netware separately.
SoftWindows 1.x came pre-installed with MS–DOS 6.21, whereas SoftWindows 2 comes pre-installed with MS-DOS 6.22. Your previous hard disk will be upgraded automatically.
Once all the MS-DOS files and Insignia utilities have been upgraded, the CONFIG.SYS file should be modified for use with SoftWindows 2, as follows:
Delete the following line from the CONFIG.SYS file on your D: drive, as it is no longer required:
DEVICE=C:\INSIGNIA\EM_DRVR.SYS
The following Table represents some of the files that are installed in the SoftWindows installation directory by the installation procedure. For a full list, open the Software Manager from your Toolchest, and click on “Manage Installed Software.”

The following Table represents some of the directories that are installed on the C: drive.
Table 5-3. Directories Installed on C:\
Directory | Description |
|---|---|
DOS | MS-DOS files |
SUPPDISK | The contents of the MS-DOS supplementary disk |
INSIGNIA | SoftWindows utilities and drivers |
NOVELL | Novell drivers and configuration files |
WINDOWS | User's individual Windows files, used together with files on the G: FSA drive |
Table 5-4. Files Installed on C:\
Directory | Description |
|---|---|
The MS-DOS command line interpreter. This is a standard part of MS-DOS and should not be modified. | |
MS-DOS boot configuration file. This is used to set MS-DOS configuration options and load drivers when SoftWindows is started. | |
MS-DOS batch program executed when MS-DOS starts up. This is used to set MS–DOS configuration options and load drivers when SoftWindows is started. |
When you install an MS-DOS application, the installer may modify the CONFIG.SYS and AUTOEXEC.BAT files for you or instruct you to modify them. To do this, use any text editor, such as MS-DOS EDIT.
To open MS-DOS EDIT and the autoexec.bat file, type at the C:\> prompt
edit autoexec.bat |
then hit the Enter key.
The following FSA drives are configured by default:
FSA drive | Description |
|---|---|
E: $HOME | The user's Unix home directory. Files |
H: $HOME | here can normally be modified by the user. |
G: $SWIN2HOME/windows | The network part of Windows, used together with files in the C:\WINDOWS directory. Files in this directory should not normally be modified, although installing a Windows application may add or modify files here. |
SoftWindows is installed with Windows 3.11 on the C drive.
Installing Windows in its network style is a two-stage process. The full installation has already been done when you install SoftWindows, so it is unlikely that you will have to do further Windows installation. However the following explanation may be useful if you have special requirements.
Windows is installed from a set of compressed files, similar to those supplied on floppy disks by Microsoft or a PC supplier.
These files are supplied in the MS–Windows 3.11 setup files section of SoftWindows which may be selected when SoftWindows is installed (this section is not installed by default). They are installed in the directory $SWIN2HOME/winsetup.
To install all of Windows 3.11 on your C: drive, type the following at the C:\> prompt:
win2c |
and press Enter as requested.
This installs all of the files required for Windows on your C: drive, allowing Windows to be run without reference to any FSA drives.
 | Note: This method of Windows installation will require each hard disk drive to be at least 30 Mbytes. |
The MS-DOS PATH environment variable specifies the directories to be searched for executable programs as a list of drive and directory names, separated by semicolons.
When you type a command at the MS-DOS C:\> prompt, MS–DOS first searches the current directory, then each of the directories in the PATH list. If it cannot find the program after this search, it prints a Bad command or filename message.
The PATH is also used by Windows to locate library files with the suffix “.DLL”, known as DLLs.
Note that this use of PATH differs from its use in Unix, because a Unix shell does not search the current directory unless the directory appears in the PATH.
We recommend that you include the C:\INSIGNIA directory in the MS-DOS PATH before C:\WINDOWS and G:\.
