Moved to "Windows Guests", as question is not relevant to "Windows Hosts".
Sorry, I only directed you to the tutorials area, it isn't my tutorial so I can't answer questions about it. Incidentally, please provide a link when referring to another topic, so I can be sure what you're referring to. In the meantime I'm assuming it's this one:
Howto: Set up Win 3.x with 1024*768 resolution.
There's often a separate discussion topic to discuss each tutorial, perhaps you might want to search for that.
One thing: you seem to have a self extracting zip which you unpacked on the floppy - running out of space on the floppy as you did you. It would probably be better to copy the file to a (virtual) hard disk directory before unpacking it. In fact I just checked the tutorial and it also tells you to do exactly that.
