[Coco] NitrOS-9 Cobbler Problems

[Bob Devries]

Yes, Joel,

You can use 'ded' to access the disk this way:

ded /dx@

Where x is the drive number where your virtual disk resides. Then use the 
'S' command and type 4C8 in response to the 'SECTOR =' question. 'Q' quits 
back to the command line prompt after the ubiquitous 'are you sure' prompt.
