Whoops!  I missed a couple of things in my first reply.  NewHandle() needs
a fourth parameter at the end: 0L or NULL.

You don't really need to bother with that--GS/OS will already put up a
volume-mount dialog; you can override that using SetSysPrefs, but there's
no need.  Under 5.0 there is the option of removing the Cancel button
from the dialog, which is sometimes appropriate.  (You really shouldn't
kill the system with SysFailMgr from an NDA, by the way!)

Not sure what ORCA/C will do with this, but I'd cast the second parameter to
an integer, like this:

         SFStartUp(memID, (int)(*toolsZeroPage));
