This really does 4 things:  It does a low level format to 80 tracks and 18
sectors (the equivalent of "superformat" or "fdformat" under Linux), it creates
a filesystem (FAT) with directories, (The equivalent of "mkdosfs" or "mke2fs"
under Linux), it adds the operating system files io.sys and msdos.sys and the
command.com command shell (The equivalent of adding a kernel and bash shell
under Linux) and it creates a boot record at the beginning of the floppy (the
equivalent of installing the LILO or GRUB bootloaders under Linux).

Freedom implies choice.  There are a thousand bazillion ways.

Rawrite is some dos utility to copy an image to an already low-level formatted
diskette, that image could have anything in it, any filesystem, any bootloader.
Dd is used like rawrite only it runs under Linux.  Makebootdisk is probably
some *distribution's* utility, not a core Gnu/Linux command at all.  Which
distribution are you finding it in?

Then get tomsrtbt and install it.  Customize it if you need to.

I dunno.  There is no "Linux".  there is only RedHat, Debian, Mandrake, SuSE,
Slackware, etc.- they are all *DIFFERENT*.  They may all have *DIFFERENT*
scripts included to automate the 4 steps of low-level formatting, filesystem
creation, loading the filesystem with a kernel and libraries and shell, and
installing a bootloader on the master boot record.  I only do tomsrtbt- I
don't use RedHat or Debian, I do it the hard way from scratch- I don't know
how those products work.  Probably some of them can make standalone bootdisks.

Good!  Then you are done?  I don't understand the question.  Tomsrtbt is a
stand-alone distribution, you can make tomsrtbt under tomsrtbt by typing:

	clone.s
