You'll find the &rawwrite.ttp; program in the same directory as the floppy disk images. Start the program by double clicking on the program icon, and type in the name of the floppy image file you want written to the floppy at the TOS program command line dialog box. Since the current release does not yet support booting from floppies to start the installation, there would be no point in doing this on Macintosh Systems. However, these files are needed for the installation of the operating system and modules, later in the process.
