I am using a FreeDOS floppy boot disk made from sys.com of FreeDOS (I am using them on virtual box and floppy disk is virtual).

I have wasted all my day trying to make an AUTOEXEC.BAT which loads ctmouse (an app for using a mouse on FreeDOS), and HIMEMX (High Memory Manager).

With ctmouse, I just use

lh A:\folder\CTMOUSE.EXE

which works perfectly, while

DEVICE=A:\HIMEMX.EXE

does not work. It gives the error:

Bad command or filename -'DEVICE'.

Could anybody help? I have tried several things to solve this problem, but none of them worked.

FreeDOS boot disk configuration

DEVICE=commands belong in config.sysnot autoexec.bat.

DEVICE

Usage: device=[d:][path]file [options]

Load the device driver specified by d:path\file (into conventional [low 640KB] memory).

The options are for the driver itself; refer to documentation that came with your particular device for supported options and their usage.

e.g. device=himem.sys

Source Config.sys Options

How do I load ctmouse, like autoexec.bat? lh is not a config.sys command

Application such as ctmouse can still be loaded in autoexec.bat.

Examples:

IN A .BAT FILE / AUTOEXEC.BAT:

lh C:\fdos\bin\mkeyb.exe

lh C:\fdos\bin\ctmouse.exe

Source Command: autoexec.bat
