It's normal that DosBox boots on Z:. Let's take an example. Let's say that you installed World of Xeen in a directory named Xeen, situated in another directory named oldgames (where you store all your oldies that need DosBox to run) on hard drive D:.
On the Z: prompt you type
mount c d:\oldgames
The DosBox will then confirm that your virtual hard drive c: is now indeed your oldgames directory.
But the Z: prompt is still here. So type
cd c: and you are on c: (which is really d:\oldgames, as you and i know, but the computer is fooled). You can now go to any of your old games. For xeen, type
cd xeen (or cd whatever game directory's name, for another game). Once you see the C:\Xeen\ prompt you just type
Xeen and here you go.
I hope this was clear. :blink:
So in case you haven't noticed you need a little Dos skills too. And then if you finally manage to launch the game, you'll probably experience sound problems. We'll talk more if it is the case, but one step at a time.
