NOT
READY:
SELECT
CODE
NN
- While loading. The media (Volume) was removed
from the device (e.g. a floppy disc was pulled out of a disc drive), the device went offline,
or
a
hardware problem caused the device to become
"not
ready".
UNRECo!.IERABLE
DATA:
SELECT
CODE
NN
- Part of the operating system
is
not readable. Possible
causes: media failure or mass storage device hardware failure.
END
OF
!.loLUME:
SELECT
CODE
NN
- Attempt to address or read past the
end
of a volume. Possible
causes: corrupt system, media failure or mass storage device hardware failure.
CTRLR/UNIT FAULT:
SELECT
CODE
NN
- Hardware passed initial self-test. However, It failed while
being used to load the operating system. Possible causes: computer (interface card) hardware
failure or mass storage device hardware failure.
Io
TIMEOUT:
SELECT
CODE
NN
- Mass storage device failed to respond fast enough while attempting
to load from
it.
Possible cause: computer hardware failure, mass storage device hardware failure,
or
the media was removed during loading.
CS80
DEVICE:
SELECT
CODE
NN
- Indicates a mass storage device hardware failure.
TAPE
DE!.IICE:
SELECT
CODE
NN
-Usually indicates a tape device (HP 7971A, HP 7974, HP 7978)
hardware failure. Can also indicate a failure on the
HP 27110A HP-IB Interface. Tape errors
covered are:

Parity Error".
HP
I B
CARD:
SELECT
CODE
NN
- Transaction to the indicated HPIB interface card was terminated
due to a probable interface card failure.
SCM
NOT
FOUND.
- Indicates a computer hardware failure
on
the computer's System Control
Module.
BAD
Io
BUS:
SELECT
CODE
NN
- Indicates a computer hardware failure
on
the computers
first
lOP,
or a
bad
SCM. The lOP does a write/read to the SCM during this test.
BAD

CODE
NN
- Indicates that Non-Volatile Memory failed
its
self-test. Possible cause:
SCM failure.
BAD
RTC:
SELECT
CODE
NN
