[Coco] HDBDOS/drivewire discovery

[Bob Devries]

My RSDISK programme was written to access the files on a virtual disk image 
file. At the time, I did not envisage having multiple "disks" in a file.

Having said that, it should be quite trivial to modify the source (which is 
included in the archive on RTSI) to ask the user for a disk number (0 to 
255), and multiply that by 161280 to get the offset to the wanted disk in 
the image file.

I did write a small util using Dev-Cpp to split a disk image into its 
component disks, but I can't find that just now. Still, the principal is the 
same.

The only caveat I can think of is that for the above offset to work 
correctly, the disks in the image *must* be 35 tracks, 18 sectors and 256 
bytes per sector.
