To be specific the DOS I use, as do many others, has the following drive 
table
drive     value
0          1
1          2
2          $41
3          $42

This makes all drives singles but includes using the second head. The 
standard table is
drive    value
0          1
1          2
2          4
3          $40

I should also point out that one can (and I have) expand the OS-9 drive 
tables in the same manner so that both true double sided disks and dual 
singles can be used at the same time.
