[Coco] SDC Question

[L. Curtis Boyle]

Sorry for the late reply (been busy with the Fest, work, and a ton of driving). 
Basically, I have a 128 MB NitrOS-9 virtual hard drive image that I use on a real Coco 3, using the CocoSDC. I would like to, from within NitrOS-9 itself, access the floppy DSK images as well, but I don’t see anything in the docs about how to mount/change floppy DSK images while still remaining on the hard drive boot. I also wouldn’t mind technical docs on how to do things on the SDC card, so I can make utilities in NitrOS-9 to mount, create, etc. DSK images, directories, etc. (If all of that is possible). Also, I don’t know if it will mount a PC style disk image (512 byte sectors) and allow either the PCDOS utility or the MSF file manager/SDisk 3 disk driver combo to directly access the PC files on such a virtual disk. I can do all of this on real floppies under NitrOS-9 (and what I have been doing so far is copying to/from real floppies as an interim step to move files between the CocoSDC floppy images and the NtirOS-9 hard drive DSK image), but would love to this all without leaving NitrOS-9 at all.

However, this program VEMUDSK just works with OS-9 floppies in the Basic partition. It provides a simple method for altering your OS9Boot file if on a virtual floppy.
