Operating Instructions
3.5 AUTOBOOT TO PRIMOS
A
successful power-up and AUTOBOOT sequence is completed in about two
minutes.
The AUTOBOOT to PRIMOS sequence can be initiated via one
of
two ways:
@e
At system power-up
e
An operator command during Control Panel Mode
The AUTOBOOT sequence consists of thirteen steps.
Some of these steps
are accompanied by status messages from the Diagnostic Processor.
If
an
error
is
encountered
during
the AUTOBOOT to PRIMOS sequence an
appropriate error message is displayed and the VCP enters CP mode (see
the VCP CP Mode subsection in this manual for details).
Refer to
the
Troubleshooting
section,
Chapter
6
of
this manual for AUTOBOOT to
PRIMOS error message information.
3.6 VIRTUAL CONTROL PANEL (VCP) OPERATION
The VCP replaces the System Option Controller (SOC).
It
provides
an
asynchronous
interface
for
the
system console, as well as a serial
printer interface.
Through
the
system
console,
the
VCP
controls
system
operations
such
as
automatic
program loading (BOOT), power
failure sequencing,
and
timing.
In
addition,
the
VCP
is
the
asynchronous interface for the system console;
thus replacing the old
System Option Controller (SOC).
Because the VCP can function in local
or
remote
mode,
the system console can be connected directly to the
VCP or remotely, via a modem.
Three operating modes are available on the VCP:
System Terminal (ST),
Control Panel (CP), and 280 micro-processor microcode Debugger
(ZCD).
In
ST mode, the VCP performs all the functions of the system console,
such as:
®
Bringing up PRIMOS
e
Sending messages
@
Logging out users
In CP mode, the VCP performs control panel functions such as:
@
Booting PRIMOS
@
Reading register set locations
@
lIscading and running programs
ZCD mode is used to debug the VCP board at the Repair Center.
CAUTION
ZzCD must NEVER be used while PRIMOS is operating.
ZCD
should
only
be used when debugging the VCP board at a Repair Center.
