Not just a way to get to OS9. If one wanted to JUST use OS9, then yes, DW4DOS would be the way to go.

OK, I see. I always use DRIVE# to access the different HDBDOS drives,
while having a pure NitrOS-9 in drive 0.

That image is equipped with a EmuDsk boot and they wanted to replace it with a boot for DW4 so they could use BOT RSDOS and OS9 on their real Coco. The post wasn't about just about booting into OS9.

Alright, so the point is not to run NitrOS-9 or HDBDOS or both of
them, but to emulate the difficulties you had in combining them on the
real hardware :) Well, fair enough, I can approve of such rigor, no
"cheating" for convenience. I just see the irony in going through all
the hoops to emulate it so closely, but still using a special
emulation driver so that you anyway cannot use the same software as on
the real thing. OK, at some certain user level, not looking under the
hood, everything looks the same, I can buy that.

Just use the "SuperIDE.dll". It will use the non-dw4/becker "HDBLBA.rom" version of HDBDOS without modification.

Good to know. So why are you using emudsk instead of the IDE emulation
where you could have used the same images as on the real thing?
