The following paragraphs describe the Windows 3.1 configuration on the 6100

Computer.  NorandĆspecific issues are emphasized.  General information on

installing and configuring Windows 3.1 itself is available from Microsoft CorporaĆ

tion and other organizations.

You can install Windows on a 6100 Computer by copying the Windows diskette to

a memory card or by copying the files to the RAM drive.  You can then start WinĆ

dows by running the WIN.COM program.  A table in subparagraph Windows

Components, on page 3Ć3, lists the files provided by Intermec Technologies CorĆ

poration, as well as a brief description of each.
To illustrate a complete boot sequence from DOS into Windows, the Windows

configuration also includes DOS startup files such as COMMAND.COM,

AUTOEXEC.BAT, and CONFIG.SYS.

The Windows 3.1 minimal configuration is shipped with all the files necessary for

operating Windows in both Standard and Enhanced modes.  Where possible, you

should run Windows in Standard mode.  Standard mode can be configured into a

much smaller footprint and can provide better performance.  You can start StanĆ

dard mode by using the /s" option when running WIN.COM.  For more informaĆ

tion on files that can be removed from the configuration, if Enhanced mode is not

required (refer to Windows Components, on page 3Ć3).

The Windows 3.1 package, supplied by Intermec Technologies Corporation, is

shipped with a default configuration appropriate for the 6100 Computer.  It

should require no further configuration to run.

The Windows startup sequence is as follows:

1. MSĆDOS boots and processes CONFIG.SYS and AUTOEXEC.BAT.
2. AUTOEXEC.BAT runs WIN.COM.
3. WIN.COM displays the Windows 3.1 logo and launches DOSX.EXE, the

standardĆmode DPMI server.

4. DOSX.EXE loads WSWAP.EXE and launches KRNL386.EXE, the Windows

kernel for 32Ćbit processors.

5. KRNL386.EXE initializes GDI.EXE, USER.EXE, the system drivers

(mouse, keyboard, etc.), and the installable drivers.  During and after this

step, the SYSTEM.INI file is referenced to locate drivers and driver configuĆ

ration settings.
