[Coco] OS-9 DS floppy config - SUCCESS!

[Chad Hendon]

It seemed logical to me to apply the SIXMS first since it was simply replacing a few bytes whereas the DISKFIX, identical to the one you posted, was more lengthy.  I noticed something curious to me in the article on the OS9 patch.  It shows a 2nd 6ms byte that was changed from 03 to 00...just like I did in the D0/D1 by Dmode.  Wonder if its related.  Oh well, in any case it seems the end rusult is a working CCDISK even if it was a bit mutilated.  I wonder if NitrOS9's RB1773 was built off the CCDISK or if they started from scratch.

Yeah, Chad,
That makes a lot of sense. Of course, the driver (CCDISK) must be able to 
*use* the stepping rate variable in the descriptors (D0, D1). If it just 
ignores it, then it ain't gonna work. Also, was the SIXMS patch to be 
applied *before* or *after* the FIXDISK patch? I'd need to see the assembly 
listing to make further sense of that.
