CPM3.DOC - Installing ConIX V22.12 under CP/M 3.0
-------------------------------------------------
The ConIX Operating System provided on the distribution diskette
was designed to function optimally under the CP/M version 2.2
operating system. If you are installing ConIX under CP/M Plus
version 3.0, there are a few general steps you should follow.
INSTALL.COM - This program will install ConIX on your system.
CP/M 3 users will probably have to disable at least BDOS error
vector patching in order to get ConIX to work at all. You may
also have to disable the ExpanDisk feature or BIOS patching
entirely. What must be disabled varies from system to system.
There is no real scientific way of knowing what can be left
enabled and what should be disabled. Only trial and error will
tell for sure.
CPM3CCPR.COM - This program generates a replacement CCP.COM which
you can install into your system. This file is not ConIX itself,
but simply a loader which will insure that ConIX is automatically
loaded each time you cold boot your system. We felt it necessary
to provide this program since the prescribed auto-boot patches
often will not work under CP/M 3.
When you run CPM3CCPR, a new file CPM3CCP.COM will be
automatically generated. This new file is pre-relocated to load
at the top of TPA memory. Therefore, before running CPM3CCPR,
make sure that system memory is organized as it will appear when
ConIX itself is running (namely, all TPA region patches
installed, if any).
To install the new CCP, copy your current CCP to OLDCCP.COM,
erase CCP.COM, and then copy CPM3CCP.COM to CCP.COM. Reboot your
system to have the new CCP load.
CPM3CCP has a few nice features. Firstly, when CPM3CCP is
invoked, it will look for the presence of a file A:NOBOOTCX.SYS.
If found, OLDCCP.COM will be loaded and executed instead of
CONIX.COM. If ConIX is to be loaded, a message will be displayed
while it is being read off disk. You may abort to OLDCCP.COM by
simply hitting CTRL-X. Remember, if you BYE out of ConIX, you
will get CPM3CCP.COM which will then throw you right back where
you came from. If you need the CP/M 3 CCP, be ready on the CTRL-
X key after running BYE.
CPM3FIX.XCC/COM - Some implementations of CP/M 3 might cause
trouble as far as BDOS error messages are concerned. The symptom
is flakey operation or a downright crash after a CP/M BDOS disk
error message is printed. If this happens, you'll have to run
CPM3FIX each time ConIX is cold loaded into your system.
The best way to do this is to use MENU to set a program to
execute automatically when PROFILE finishes setting the system
configurations. The command [J] CPM3FIX should do fine. If you
are already executing another Command Language program, execute
CPM3FIX from within it.
CP/M 3 RSX FEATURE - Since ConIX was written for CP/M 2.2, there
is currently no support for Resident System Extension invocations
from under ConIX. Any RSX's which are to stay permanently in
memory should be loaded before ConIX is cold started.
ll then throw you right back where
you came from. If you need the CP/M 3 CCP,
