Hehehe I do a similar sort of thing with Linux and setfdparm, though to 
be honest I mainly use 3.5" disks these days :)

The relevant section of my /etc/fdparm, that I use with both Dragon and 
CoCo (as they are both 40/80 tracks 18x256 byte sectors / track).

Of course for a 35 track ECB disk, I'd just use the 40 track variants.

Cheers.
