Table B–2 (Cont.): Model 400 Standard Console Error Mes-
sages
Error Message Meaning
?47 Insufficient working memory for normal op-
eration.
Less than 256 Kbytes per processor of
working memory were found. There is in-
sufficient memory for the console to func-
tion normally or for the operating sys-
tem to boot.
?48 Uncorrectable memory errors—long mem-
ory test must be performed.
A Model 400 memory array contains
an unrecoverable error. The con-
sole must perform a slow test to lo-
cate all the failing locations.
?49 Memory cannot be initialized. The specified operation was attempted
and prevented.
?4A Memories not interleaved due to
uncorrectable errors:
The listed arrays would normally have
been interleaved (by default or explicit re-
quest). Because one or more of them con-
tained unrecoverable errors, this inter-
leave set will not be constructed.
?4B Internal logic error in console. The console encountered a theoreti-
cally impossible condition.
?4C Invalid node for Z command. The target of a Z command must be a CPU
or an I/O adapter and must not be the pri-
mary processor.
?4D Invalid node for new primary. The SET CPU command failed when at-
tempting to make the specified node the
primary processor.
?4E Specified node is not a processor. The specified node is not a processor, as re-
quired by the command.
?4F System serial number has not been
initialized.
No CPU in the system contains a valid
system serial number.
?50 System serial number not initialized on
primary processor.
The primary processor has an uninitial-
ized system serial number. All other pro-
cessors in the system contain a valid se-
rial number.
?51 Secondary processor returned bad
response message.
A secondary processor returned an un-
intelligible response to a request made
by the console on the primary proces-
sor.
