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

Tue Aug 10 22:43:20 EDT 2010

Well... did a quick google and discovered what is going on.  This guy here seems to have outlined the basics of it back when v2.00.00 was released.
http://www.coco3.com/community/1986/01/new-os-9   Apparently, some functions (i.e. 6ms stepping, etc) are applied by modifying both the CCDISK and the D0/D1 descriptors.  Well it figures..since it took that to make it double sided too.

There was a SIXMS script file on that OS9 disk as well that apparently patched CCDISK for 6ms.  Not sure if that conflicts with the D0 D1 setting or just the NitrOS9 DMODE wasn't setting the right offset byte in the OS9 D0/D1 or what.  The SIXMS script is below.  What do you make of it?

L CCDISK
. .+1F9
=10
L CCDISK
. .+1FF
=08
L CCDISK
. .+200
=8B
L CCDISK
. .+2DD
=40
L CCDISK
. .+2E8
=00

Well dude I haven't read the manual.  All I know is I applied the "patch" to CCDISK, set the STP to 03 to match what the NitrOS9 STP setting was, and it ruined the stepping rate.  It SUCKED.  I put it back to 00 and it was quiet and quick like I'm used to 6ms being in NitrOS9, DECB, etc.

Hi Chad,

the "standard" OS9 level 1 disk device descriptor has its stepping rate at 
offset $14. The options are 0=30ms, 1=20ms,2=12ms,3=6ms.

Pages 39 and 40 of the OS9 Technical Information manual refers.

Hope that helps
