There are no autoexec.bat nor config.sys files under DOSBox. You must make a bootable floppy containing that device driver and boot it from DOSBox. Search the forum and read the documentation. 😎

PS - There is an autoexec section inside DOSBox configuration file but I don't remember if you could put device= statements there. I think not, but you should check it out nonetheless.

nope devices loading is not supported. (at least not officially)

For a programm i needed to use this command

device=c:\drex_drv.sys

Eh - why do you need that?

I need this file to put passwords to a database that only runs in dos
Without this the database dasnt work 🙁
Btw device is not supported and external boot is out of the question since the database will be on a flash and my notebook dont have a floppy.

Regards and thx for the answers 😀

But.... is there a way ?

you can boot real dos from a disk image in dosbox. that should allow you to type almost everything you want in config.sys

I'm sure there was a program that loaded the devices for you so you could load them in a bat file. It was used for iso image mounting since it required a special cdrom driver to be loaded (which was .sys of course).
