This message is displayed
when the number of boards recorded in the Non-Volatile Memory (NVM) is greater than the actual
number of boards in the stack. If the number of boards in the stack is greater than the number
stored in the NVM, the number in the NVM is updated to reflect the larger stack size.
Fatal Error Messages
SysteM halted due to double bit MeMOry error on MC
#
NN CCCCCCCC
Where: NN
=
MC #
CCCCCCCC
=
Last healer content for that MC (in hexadecimal).
This message is displayed when a double bit error has been detected by the memory controller
hardware. The MC# is in terms of memory controller boards (counting up from the bottom of the
stack). This information is also recorded in the NVM.
If more than one MC with a double bit error is found, only the last error is displayed. If no double bit
errors are found, but the CPU was interrupted for a double bit error, "No DBE found" replaces NN
XXXXXXXXX. DBE information is stored in the NVM.

This message is displayed when there
is insufficient memory for the operating system and user subsystem. Check the stack self-test lights
to see if any stack components have failed self-test. Also, check the memory configuration of the
computer to see if it is large enough to accomodate the system and options which are being loaded.
SYSTEM HALTED: lnCOlrlpatible lOPs -
This message indicates that an illegal combination of lOP
boards were found at power up. lOPs of Revision 2.1 or earlier are not compatible with lOPs of
Revision 2.2 or later.
System Error Message
Sy s t elll hal ted - >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).
