ecc The error correction or detection logic is faulty. This indicates a bad CPU
module, memory module, or base system module. Reseat the CPU module, all
memory modules, and the base system module; if the problem persists, replace
the memory module in slot 0 (see Chapter 9 ). If the message reappears, copy
the entire message and call your system manager or the Customer Support
Center.
fpu The math coprocessor in the CPU module is faulty. Copy the entire message
and call your system manager or Customer Support Center.
mem Random-access memory (RAM) is faulty. Make sure that all the memory
modules are firmly seated in their connectors in the system unit and then
run the memory test. Type t 3/mem * and press Return. The memory test
checks every memory module, taking several minutes for each one. If it finds
a problem, it displays a message with one of the following formats, where
slot-number indicates where the faulty memory module is installed.
?TFL: 3/mem (1:board
slot-number
, MBE=

?TFL: 3/mem (2:board
slot-number
, too many SBEs:

Remove or replace the faulty memory module (see Chapter 9). You must retain
at least 16 megabytes of memory for your workstation to operate correctly.
After removing or replacing all faulty memory modules, run the memory test
again. If the test still reports a problem, copy the entire message and call your
system manager or Customer Support Center.
mem/float10,
mem/init,
mem/select
A memory module is faulty. Copy the entire message and call your system
manager or Customer Support Center.
misc/halt The halt button or the built-in halt program is faulty. Copy the entire message
and call your system manager or Customer Support Center.
misc/kbd The keyboard, keyboard cable, or connectors are faulty. Make sure that the
cable is connected properly (see Chapter 1). Then turn the system unit off and
on. If the test message appears again, try replacing first the keyboard cable

and call your system manager or Customer Support Center.
misc/mouse The mouse, mouse cable, or connector is faulty. Make sure that the cable is
connected properly (see Chapter 1). Then turn the system unit off and on
again. If the test message appears again, replace the mouse. If the message

Customer Support Center.
