DOS was very basic. Filenames took the 8.3 format - maximum of 8 characters followed by the "." and three characters for the extension. This is why Jazz's main executable is JAZZ.EXE
Drives are identified by a letter - C would be your first hard drive, A and B are your floppy drives, and any further drives are D, E etc. CDROM drives typically started at letter D (or the first free letter after your hard drives).
To change to a drive, you use a colon as a drive specifier, eg
<return> means press RETURN, don't type "<return>"!
To change directory, use CD.
Would switch to the directory "jazzy", so long as it can be reached from your current folder. If you're not in C, then you need to switch with "C:" first, before switching to "jazzy" - you cannot simply type "cd c:\jazzy", without switching to "C:" first. So, assuming that you're in "Z:" (which is denoted by the prompt being "Z:\>" in the DOS window, you would type
Code:
C: <return>
cd \jazzy <return>
The backslash specifies that you want to switch to the directory "jazzy" in the root of the drive. All directory separators are "\", as opposed to the linux "/".
When launching the game, you don't need to specify the ".exe" part of the filename (though it won't hurt if you do), so you just type
Assuming of course that the exe is "JAZZ.EXE"... You can find out by typing "dir <return>" when you're in the c:\jazzy directory. If you get no files listed then either you've gone wrong copying your files over, or perhaps you have some hidden files and folders. You can discover these if you type:
to remove the hidden attribute, and then list the files again with "DIR <return>".
I don't have DOSBOX installed at the moment, but I will do tomorrow when I get home from work. When I get it on my panda, I'll post more specific instructions as to how to get things going.
