[Coco] B&B XTROM

[L. Curtis Boyle]

The XT ROM does not have anything hard coded into it concerning the  
drive; it uses sector 0 like other OS-9 drives. The only exception is  
if you want two different boots - if you are going to use the 2nd boot  
then it used either track 128 or 129 (can't remember) for the  
alternate boot track.
