System Loader Message
Each of the System Loader Messages are explained below. Possible causes
for
many of the
messages are provided.
If the message begins with "ERROR:" the system halts after issuing the
message.
If the message begins with "NOTE:" the message provides information
and
the computer
continues operating.
The computer
will
attempt to output messages to a Graphics Display Station
if
one
is
present. If
it
can not find a display station,
it
will
output messages to the serial interface at select code
O.
Often the computer attempts to identify the device to which
it
was "talking" when the message was
generated. The trailer
"SELECT CODE NN"
is
appended to the message to indicate which select
code
(110
port) of the computer caused the message. Select codes 0 through 7 are on the computer
and
are controlled by the
first
lIO processor (lOP). Select codes 8 through 15 are
on
the
110
Expander
and
are controlled by the second lOP.
