This is what I'm told, all these steps were taken except step 5.
Installation:
-------------
(1) Create DEVS:Kickstarts and copy all your Kickstart images to it. This
directory is searched automatically in the GUI mode (can be overriden
by the KICKDIR option if you want).
(2) Find proper Kickstart header files (you may find a list of them above).
Rename Kickstart files to match the names of the header files -- for
kick39115.A3000.BETA.kshd, the Kickstart image should be renamed to
kick39115.A3000.BETA. (It's also possible to rename the header files
according to names of Kickstart images, but it's a bit confusing.)
THERE ARE NO KICKSTART IMAGES IN THIS ARCHIVE
If you don't know the exact name of .kick file to be used, consult the
KickInfo utility (see its doc for how to do it).
(3) Copy the executable files to some place, preferably to some that is
included in PATH. It's better to copy the MKick executable itself to
C: to allow using it before any paths are set.
(4) If you want MKick to work automatically, insert it as a FIRST line of
your Startup-sequence. It allows MKick to handle all operations requiring
system reboot (switching from one Kickstart in RAM to another one etc.)
without user intervention. When you hold down the left mouse button
during system reboot, the GUI screen will appear.
(5) If you want your startup scripts to be switched according to Kickstart
version, install the SwitchScript utility (see its .doc for how to do it)
So, I'm still not not able to get it to work.
***UPDATE: Moved header files into devs directory - now works, don't see copying these files mentioned***
