Below are some initial instructions.

These are backout files.  To install these you can start with a 
formatted disk or you can rename all directories and files in a MSHEAR
or USHEAR system, then backin and then deldir -qf the renamed 
directories.  This is not as hard as it sounds since you need only
rename stuff in the /h0 directory.  Try the procedure file 
/h0/mshear/cfg/sysboot_1/backover, or the more specialized scripts 
back.doit.4120 included in sample.procedures.  If you are 
renaming directories, it is helpful to create at least 
/h0/SYS/password before launching the backin in case there is an 
error somewhere and you need to log in.

AN IMPORTANT NOTE FOR Q680 types:
The release contains a file /h0/OS9Boot.new  This is a valid boot file
for OS9 systems that boot from disk.  However the file must be linked
in order to be found during bootup.  The file itself has not changed
with MSHEAR and if you have a disk working since 1994 you can continue 
to use it without any changes, just delete this new file using
(attr -w OS9Boot.new ; del OS9Boot.new).  If you want to use the new 
file, you must link it by entering the following before booting;
chd /h0fmt
OS9gen /h0fmt -q=os9boot.new -eb=100k

In MSHEAR, the file startup remains running so you cannot delete it, 
just rename it and then after rebooting you can delete it.  
The backin will not make /h0/startup, instead it writes startup_choose1. 
Edit this file for the system type and name it startup.  

If you downloaded a file mscfg990722.lzh or later, you need to extract this
to update the configuration files.  Do this after you have completed the
backin but before reboot.  

If you have already an MSHEAR development system create a key archive 
to extract on the new system;
chd /h0
lharc -at K990701.lzh MSHEAR/CFG/NETWORKS/BOSAI
MSHEAR/CFG/NETWORKS/DEFAULT MSHEAR/CFG/STATIONS/QT2
you can then extract this on the new system, 
edt /h0/mshear/cfg/.selection
for this key and your off and running.

If you do not have an mshear development system, you start now.  make a
new directory in /h0/mshear/cfg/networks  for example BOSAI.  Copy all the 
files in MASTER to BOSAI.  
Edit the files *.sample to your needs.  Copy hosts.sample to hosts.
You can change the file names *.sample to *.netname.  
Create a station directory as /h0/mshear/cfg/stations/new
and copy one of the example keys into this directory.  
Edit the key for your needs.  Edit /h0/mshear/cfg/.selection to indicate 
this new station directory.

We currently expect patches for;
68000 SLIP support
4120 and 680 clock program enhancement: old works, new one works better
configuration template refinements, these are lharc files. see script
 in the distribution /h0/mshear/cfg/sysboot_1/save_cfg.zsh
