Hi all, as requested, follows the link for the image.

http://www.4shared.com/zip/1Y1S8dKA/ide.html?

It's a 276MB image, but if you don't have a bigger CF card, you can
just split it at the 245MB position and copy it to your 256Mb CF card.
Didn't test but maybe sidewalk will do it for you since it will stop
after the CF's end.]

So at the menu you can choose 1 for level 1 and 2 for level 2. There
are 4 boot images, the reason for that is to keep 2 SAFE MODE images
in case you screw a working ones.

252 - SAFE level 1 boot
253 - level 1 boot
254 - SAFE level 2 boot
255 - level 2 boot

I didn't test on coco2 (still don't have one but i'll put my hands on
a tandy 64k later this week). The level 1 will probably run out of
memory for any serious app. is up to you to change the
nitros9/6809l1/bootlists/superdriver_ide_32.bl and remove the non
desired modules. Probably you will need to get rid of DW3 and floppy
disks to be able to run something. Then run
nitros9/6809l1/scripts/mb.ide. it will write directly on drive image
253 on cf card. (so no need for floppies or DW for that :) ) You
notice it will ask to press C several times, the reason for that is in
order to os9gen the SAME disk you are you need the option -S,
otherwise you get a "Disk ID Change" error.

Same for level2, nitros9/6809l2/bootlists/superdriver_ide_80.bl and
run nitros9/6809l2/scripts/mb.ide it will burn on drive 255 instead.

note: before running mb.ide make sure the the STP is at correctly drive image;

dmode /ih stp=FF (level2)

or

dmode /ih stp=FD (level1)

Enjoy,
