Kludgy method:

Type in the following Applesoft BASIC program:

10 PRINT CHR$(4);"PR#6"

And save it as BOOT6.  You could write a similar program for BOOT5.

Then you can just double-click on BOOT6...wait for ProDOS-8 to load, then wait
for BASIC.SYSTEM to load, then wait for your one-liner to load, then watch as
your floppy drive boots.

Slightly less kludgy method:

Write a SYS16 program, BOOT6.S16, containing the line...

$00/2000:  JMP $00C600

As I am not presently proficient in 65816 (shame on me!) I can't give you the
details of writing that one.  And it breaks all the usual rules of GS/OS
programming.

Least kludgy method:
Obtain a copy of Eric Shepherd's ProBOOT.  Once configured, hold the Apple key
while your system boots, then you can just hit a key to boot the floppy.
