Configuration and Sample Files
When the MX3 is turned on, the operating system looks for several files in order to start up your
system. Two of these files are hidden system files that cannot be seen when you perform a DOS
directory command (DIR). The other files that are read at start up are:
COMMAND.COM
The COMMAND.COM file is essential to the operation of your system. Without it your system
cannot boot. It contains the programming for resident DOS commands (the commands which
allow you to change directories, copy, rename and delete files, etc.).
The COMMAND.COM file should be located in the root (C:\) directory.
CONFIG.SYS
The CONFIG.SYS file is not essential to the operation of the MX3, but it is essential to the
operation of certain software programs. The information in this file may be altered and some
software applications will automatically alter it during their installation process.
The default CONFIG.SYS file that is shipped with the MX3 varies depending on both the
software and hardware configuration of the unit.
AUTOEXEC.BAT
The AUTOEXEC.BAT file is not essential to the operation of the MX3. The MX3 will boot
without it. The AUTOEXEC.BAT file is a batch file that contains a series of commands. The
MX3 reads the AUTOEXEC.BAT file and executes the commands in the order in which they
appear. The information in this file may be altered and some software applications will
automatically alter it during their installation process.
The default AUTOEXEC.BAT file that is shipped with the MX3 varies depending on both the
software and hardware configuration of the unit.
For information on customizing the keyboard and display for international use, refer
to a commercially available “ROM-DOS User’s Manual”.
