Yes...  To make a long story short, whatever is in Sector 1 of the disk is 
loaded into memory at hex 0700; the first 14 bytes or so contain information
about how many subsequent sectors to load, where to place them in memory, and
where to begin execution when said sectors have been loaded.  

If no one else posts the fine points, I can dig them up for you and post to 
the net if there appears to be sufficient interest.

(This sure beats arguing about piracy, doesn't it!?  :-)  )
