Yes, you are right.  The normal Devs/Mountlist is not used.  There is
a special "Rigid DisK Block" (or something like that) section on the 
hard disk itself that contains the mountlist information.  That way you 
don't need a special boot partition.  GVP was first to market a controller
that did this.  I think Microbotics is also doing it now.  Any others?

If you look at GVPprepHD (type ... opt h) you will see some undocumented
parameters.  The one you need to use is the ASKALL one.  As good as the 
GVP autoinstall scripts are they tend to obscure things for the knowlege-
able user.  Make sure you write out the mountlist specs (there should be
a copy in the GVPscripts directory of your hard disk).  Then, booting from
the GVP floppy open a CLI and then enter the directory where GVPprepHD
resides and type "GVPprepHD ? ASKALL UNDOS" (no quotes).  Then just change
the mountlist specs you want.  Of course you can't change the size and 
partition information without causing a disaster.  I think the BUFMEMTYPE
you want is either 4 or 5 (I don't think it makes any difference).  I
suggest you increase the default buffer size also since you have memory
to burn now.  You can also edit the installation script XinstallHD to
include the ASKALL parameter (manual instead of automatic installation).

I've done this often but, of course, do have a fresh backup available. :-)

Good Luck!
