If you are looking for a tool which will help you create a floppy disk image, you can use
Magic ISO Maker.
While installing Windows 7 RC on my Virtual PC, I had experienced a driver problem. And some search on the web with Google
directed me to create a floppy image file including some device drivers. So I preferred to use the
MagicISO.
Magic ISO Maker is a simple tool and easy to use tool for building floppy images.
You can download MagicISO from
MagicISO.
