    Make a minix filesystem on the floppy:

+The stuff about ramdisk is only if you want an init ramdisk. You can also use:
+
+vmlinuz.app:	Arguments prepended to the Linux command line.
+vmlinuz.cmd:	Arguments appended to the Linux command line.
+vmlinux.dfl:	Arguments appended to the Linux command line.
+
+If there's a *.cmd file you won't be asked anything. If there's a *.dfl or
+neither you'll be asked:
+
+vmlinuz:
 
-To boot the floppy in DOSEMU
-----------------------------
+where you can type a command line to override the *.dfl file. If there's
+a *.cmd file the *.dfl file is ignored, the *.app file is placed at the
+start of the line whichever you do.

+If the file isn't called 'vmlinuz' you can still boot it by typing "=linux"

-   Press ^C to exit DOSEMU from inside monitor.c
+Escape or ^C will interrupt the boot and drop you to the '>' prompt.

+A file called 'help.txt' will be displayed upto the first line that starts
+with a '%', chunks after that (seperated by '%'s) will be displayed when
+the user presses a function key, home, page up or page down. (Note it's
+best if you try to ensure 'help.txt' is completely contained on one track
+so the file is entirely in the track buffer)
