[Coco] NitroOS-9 in CocoSDC Image 2017-11-11 question(s)

[Oswaldo Aquique]

Hi,
I'm trying to run the NitrOS-9 L2 image for 6309 included in the CocoSDC image with date 2017-11-11 (file is at \NITROS9\nos9l263.dsk - Size 30,717 KB) and I get a "NitrOS9 BOOT failed" message in the screen, along with some random characters at the top-left.

If, instead, I use the NitrOS-9 file I downloaded from NitrOS-9 wiki (file size is just 4,608 KB) it works perfectly.

Tried to download and expand the COCOSDC image again, with the same result.

My goal is to have a NitrOS-9 Level 2 (6309) image with mshell and multivue, in addition to the sdcdriver and tools.

If there any other place were I could download a functional copy of the file included in the CoCoSDC image file? If not, how can I create my own image (a total OS-9 newbie here) with multivue, mshell and tools included?

Thanks,
Oswaldo
