The procedure for loading the UNIX Operating System
normally involves the loading onto the System Disk of:

The device reconfiguration usually involves entering
the new device's logical name with the bus address as
specified in your Site Management Guide, the name the
bus or controller that the device is connected to, etc.

The installation of the UNIX Operating System is an interesting
procedure, however only for one or two times! The reason you'd
want to do this is to be able to use your computer system with
UNIX on it, to practice, and sometimes, unfortunately, because
some key system files have been lost.
Before reloading the UNIX Operating System, make sure that
you have backed up all the user files and you have given
sufficient notice to all the users about the upcoming system
down time.
Whether you are initially installing the system or reloading,
your UNIX System distribution media will likely be one of those
shown above.
The installation procedure, which on most recent systems is
a "cookbook" operation, and is described either in the
"System Manager's Guide" or in a separate "Software Installation
Guide" involves the steps listed above:
On larger systems you may have several devices which are not configured in
the distribution configuration file. You must add the configuration parameters
for those devices to the file and rebuild the system kernel. An entry is
required for each additional bus adapter and parallel device. Once you
finish the addition of all the new devices, the system, usually automatically,
will rebuild the kernel. If you did everything correctly, your new
devices will function well.
Once the basic UNIX packages are installed, you may install other
UNIX packages, such as "The Development System", "Text Processing
System", and also third-party software, provided they were purchased.
The final step of the installation usually involves the above steps:
NOTE: Several configuration files may be restored from
your backup when you are reloading the system since
in that case the system configuration usually remains
the same.
