Fine.
The startup-sequence of this "special bootdisk" floppy for OS 3.1 looked like this:
;run system/cli
;add32bit-special resetfest
;setcpu cache burst fastrom config 2 trap 2
fastmemfirst
addbuffers >nil: df0: 35
addbuffers >nil: df1: 35

When I switched on the Amiga with the Bootdisk in a flppy drive, it started to boot the floppy and after a few seconds the HDs spun up and the complete Amiga operating system booted from HD.
I just got a copy of the Bridgeboard DOS diskette very recently.
My current DOS boot disk is very plain (just a command.com)
But the Bridgeboard DOS diskette does have some more files (not many, but all files are shown in screenshot above). They might do something similar to your boot disk setup.
What I haven't tried it creating a "
config.sys" file to include running some additional commands possible (like
emm.sys). One in particular is a command "
bbsetup.com". A statement like "
device=bbsetup.com" can be added and see what happens. (This is not mentioned in the BB manual, but possibly the disk that Came with the BB had this in place).
BUT I DID TRY RUNING THE BBSETUP.COM manually, and it loads the Janus drivers[and hangs system].
(Displays the SAME MESSAGE that shows normally before the DOS boot), so my guess this triggers Code thru the BB BIOS (already/somehow. So may not be needed TWICE).
However (what if the BBSETUP is the DOS version of the JANUS library, and the two (DOS/AMIGA) need to JOIN together).
I will try this too very soon.
FROM WHAT I RESEARCHED, there are more manuals/book for the JANUS specific stuff. I don't have that.
My guess is those books are for developers, but I could be wrong.
