I wrote this to write to the bootsector of a floppy, it uses a dll and java (the dll does the dirty work, java gives a command line prompt).

You going to have to unzip it, and configure (right click and change the path in) the r.bat to locate the jre (most of the times its in C:\Program Files\Java\jre1.5.0_07\bin\java.exe but open your \program files\java\to find out, you can copy/paste its path).

I don't have a floppy drive, so I have no clue how well this works (if at all).
