CTRL-F4 is when you are using DOSBox. You know what DOSBox is, don't you? DOSBox is a ms-dos emulator. In order to use it you need to mount (think of it as "activate") as many drives as you need. In this case we need a floppy drive (where source files are) and a hard disk (destination drive).
So, you would install DOSBox and after running it a prompt similar to old ms-dos will appear...
Z:\>
And it is waiting commands typed in by us. As I have said before, the first thing we need is to mount our drives. To do this TYPE IN in the Z:\> prompt:
mount c c:\ (press Enter)
mount a "c:\installation folder" -t floppy (press Enter)
Please note that installation folder is the name of the folder WHERE YOU HAVE ALL SOURCE FILES. Using short names for folders is better, by the way.
After mounting, you need to CHANGE to the floppy to start installation.
A: (press Enter)
Prompt will change to A
A:\>
and then type in dir to see how the install program is called, most probably install.exe - install.bat - setup.exe - install.com (whatever). Just type in its name
A:\>install.exe
That's it. In our case we don't need CTRL-F4 because we aren't swapping physical floppies at all (remember we have made the program believe the A: is just a folder containing all files). CTRL-F4 is used when we are mounting the real A: drive (floppy) and we physically change floppies.
Good luck. I hope this would have clarified things a bit for you.
PS - Just because we are talking about DOSBox now, I ADVISE YOU TO READ THE GUIDELINES/FAQs in the proper section forum.
