with the booter except that it was assembled on a non-native assembler and
ported over.  Perhaps I am being sort of a purist but I'm trying to make
this work directly under OS9.  I figure I've got a fast enough machine and
all of my work files are on a fast SD card. It takes all of two seconds to
assemble the file.  So why not?

Is there a way to officially mod my work to keep it kosher with both
assembler environments?  This would mean less work in future.

so the use of a 'gen' program is no longer necessary.  If you want to
modify or change around which modules are in your bootfile then you simply
do it and re-boot.  He has taken a lot of the hassle out of the process.
However, I know that at some time I will erroneously create a boot file
that will not boot and then I'll be stuck (yes, I could switch back to DECB
and use DW but I don't want to do that).  So I want to create a boot loader
than can not only use the OS9Boot file but also, as a fail-safe, another
file such as OS9Boot.safe could be optionally selected in case I get myself
in such a bind.

Excelent idea.  Nothings really stopping us from having mutiple boot
files.  With a touch more work, you could mod my work to load the os9
modules individually - have a text file somewhere that has a list of
modules to load.
