The system is
.I idle
when no 
.I user
processes are running.
.FE
If 
.I UNIX
is running,
the system should be cleared via the UNIX SHUTDOWN PROCEDURE.
.P
The normal boot performed is a ROM BOOT.
The TAPE BOOT is performed (on the 11/45 only) when loading a
special system, 
or when a ROM BOOT is impossible.
.P
When performing any boot procedure the Power Key Switch
should be in the
.I POWER
position, the Address Select Knob should be in the
.I "CONSOLE PHYSICAL"
position, and the Data Select Knob should be in the
.I "DATA PATHS"
position.
.P
Before performing any procedure, please read that
procedure

.HU "GENERAL PROCEDURES AFTER BOOTING"
After the boot is completed,
UNIX will print a ``restricted rights'' message and tell you the
System Name and the amount of memory
available.
The latter should be checked against a previous boot
to be sure that all of memory is available. Otherwise,
serious problems can occur.

If booting as part of 
.I "SYSTEM RECOVERY" ,
continue SYSTEM RECOVERY PROCEDURE.
.L1
If bringing up
.I UNIX
.I MULTI-USER ,
perform UNIX INITIALIZATION
PROCEDURE.
