Recently I wanted to run an old DOS game called ZED (created by Bitmap Brothers, 1996) in a Dosbox on Ubuntu. Dosbox is an emulator which enables to run old DOS games and applications on a modern PC. ZED is a realtime strategy game.

After installing Dosbox on Ubuntu and putting the Software under the file system path “/home/MyUser/Desktop/Dos/Z”, I started the dosbox.

I executed the following commands in the dosbox:

mount c /home/MyUser/Desktop/Dos
c:
cd z
z.bat

The Problem

I could start the game but finally I ended up with this error message on starting the first level of the game:

Missing: MAIN.PAC
COMMANDER ZOD SHOOTS PIRATES AT DAWN!
PLEASE READ COPYRIGHT MESSAGE IN MANUAL

The Fix

It seems that an old times piracy protection prevented me to start Level 1 of the game. I had to emulate a CD Drive and start ZED again with this commands:

mount d /home/MyUser/Desktop/dos/z -t cdrom
z.bat

Finally I could start and enjoy the game.
