The easiest thing to do is to look at the device driver vectors for the slot
that contains your Disk IIs. Usually that's slot 6. Then have your program
relocate itself there.

I'd use the 64K RAM disk driver space myself. It always starts at $FF00 and
since the 64K RAM disk is such a useless device, you'll never miss it. I've 
used that location for other drivers which I've written.
