- This message indicates that either the contents of the
NVM
are not
valid
at
powerup or the clock has not been set since this condition was detected. Possible causes: a
bad
battery
on
the SCM board, or computer powered down
for
more than 2 weeks. The condition
does not stop the system operation.

AA,
SS
STATUS:
XXXXXXXX
Where:
AA
= Select code
SS
= Subaddress
XXXXXXXX
= Device or card dependent error information
(in
hexadecimal).
This error message
is
displayed as a result of the self-test failure of an
I/O
device. The select code
subaddress denote the device, and the device dependent error information indicates the nature of
the failure. System operation can continue provided that use of the failed device
is
not required.

2:
CHECKSUM
for
Se9fTiertt
NN
- When the system
is
powered up, or a system
reset
is
executed, the checksum for every code segment of the operating system
is
computed
and
compared to a checksum
in
the operating system code. When the checksums do not agree for a
segment, the segment number
is
stored.
As
a result, the segment reported
is
the last segment
for
which a checksum error was detected. The operation of the system
is
not halted, however, further
operation
is
at your own
risk.

NN
Where:
XXXX
=
"CPU#",
"IOP#",
or
"MC#_".
NN
= The Nth of that type of component (counting from the bottom of the stack).
This error occurs when the system
is
able to get completely through the board self-test
and
the
loader self-test, but a failed stack component
is
detected by the operating system. The message
indicates the type of component which has failed
and
its
relative position
in
the stack. Operation of
the system can continue,
if the failed board
is
not required.

Where: NNNNNNNN = number of bytes
(in
decimal) that are available.
<list>
= A
list
of Memory Controller numbers which had failures.
Up
to
10
MC
numbers are printed
in
10 two character fields, with no intervening spaces. For
example:
"MCs: 1
210"
indicates that Memory Controllers
1,
2,
and 10 have failed
the memory test. Memory boards (and memory controllers) are numbered from 1,
starting at the bottom of the
RAM.
This number represents
all
usable
RAM
in
the system including memory used to hold code seg-
ments.
