[Coco] coco OS9 boot ROM

[Paul T. Barton]

For hints on the code, could one
not use the Disto driver to get 
started on the code?

How would it do to burn Boot, Rel,
and the other module that go onto
track 35 into the area occupied by the
"3 musketeers", and perhaps
reverse the boot sequence that
determines whether you boot into RSDOS 
or do the OS9 command?

You could also insert code in this area
to check /d0 first, then check /h0.

--

I did this too. You must modify the
"picture" mover code to move the
rel,boot,os9p1 to the $2600 area and
then jump to $2602. Remember to
do the ram/rom to rom swaps for every
piece of code moved.

When you do it this way, the CTRL-ALT
keys must be held down at RESET and
off she goes! No floppy required.
Inside of BOOT is a piece your /H0
driver that does almost the same
as a floppy boot.
