JANUS? 2020 Hand-Held Computer (4MB) - Intermec

Defining the Startup Files
NF BC Learning About the Software

JANUS devices use two startup files to control how DOS uses hardware,
memory, and files: AUTOEXEC.BAT and CONFIG.SYS. AUTOEXEC.BAT
loads programs and defines paths. CONFIG.SYS loads device drivers and
reserves memory for processing information. The commands in the startup
files execute when you warm boot or cold boot the JANUS device.
You may modify the startup files for a variety of reasons:
• To change the default JANUS Startup menu.
• To support applications you will run on your JANUS device.
• To load drivers for your PC cards.
• To create physical RAM drives.
• To configure your JANUS device to operate in another language.
Because AUTOEXEC.BAT and CONFIG.SYS are stored on drives C or D, you
must use Auto-Loader, binary file transfer (BFT), or MakeDisk and PutDisk to
replace them.
The next sections illustrate what the two startup files may contain when your
4MB JANUS device arrives from the factory.
AUTOEXEC.BAT File
The AUTOEXEC.BAT file on your 4MB JANUS device should look like this one:
Command Line Definition
echo off The AUTOEXEC.BAT commands are not displayed on
the screen as they are executed.
cls Clears the screen.
if not exist autoinst.bat goto T2
call autoinst
goto T3
:T2
if exist d:\autoinst.bat call
d:\autoinst
:T3
These commands call the AUTOINST.BAT file, enabling
you to update drives C or D with Auto-Loader.
Do not remove these commands.
Do not delete AUTOINST.BAT from drives C or D.
set prompt=$p$g Sets the DOS prompt to display the current drive and
directory, followed by the > symbol.
set path=c:\;d:\;e:\; Directs DOS to look for commands and programs in the
root directories of drives C, D, and E. Do not add drive
G to the path, or else errors will occur when you do not
have a PC card installed.
