halted->SYSTEM
ERROR:
••••
- This message
is
displayed when the operating system soft-
ware encounters either:
•
an
unanticipated trap,
•
an
unrecoverable system software error.
The
"trap"
is
distinguished from the software error by the word "trap:" which
is
added
to the
first
line of the message.
Before displaying any messages, the currently executing
CPU disables
its
interrupts
and
causes
all
other CPUs to stop operating. The message text
is
multiple lines information
dumped
from memory
and
internal registers. The message starts
on
the top line
on
the Display
and
overwrites
any
other
messages
on
the CRT. If a printer
is
the output device
and
the message
is
more than
25
lines
in
length, the message continues to print (up to
500
lines).
