I have some questions about setting up my Quantum 40s hard disk 
with the Microbotics HardFrame using the HardFrame's RDPrep
program.

I want to have two partitions, but all of the defaults in RDPrep
assume you are only going to have one partition.  I decided to
make my partition at the point where the sectors/track density
changes, as recommended. 

    --> Cylinders 0 to 589 contain 35 sectors per track, 105
	physical sectors available.

    --> Cylinders 590 to 833 contain 26 sectors per track, 84
	physical sectors available.

My questions are:

    Do you need to (can you) set up a Rigid Disk Block for each partition ?

    If no, how does the controller know that the second partition
    has a different number of sectors/track ?

    Apparently, the recommended default for the Quantum is 32 sectors
    per track.  Is this just a compromise between the two values
    (35 and 26) ?

    What is "logical blocks per track" (asked for each partition) and
    why is the default 98 ?

    I assume it is desirable to set up both partitions with the Fast
    File System.  Is this correct ?

    What exactly do I need to add to Startup-Sequence (I am booting
    from the hard disk).  It says SETPATH must be the first command.
    What is the exact command in its entirety ?

Could some kind person send me answers to these questions and any other 
pertinent information that I might need to know.

Note: I have a stock Amiga 2000 (1 megabyte of RAM).

Thanks in advance,
