162 A change in device configuration occurred. This message is
displayed under one or more of the following conditions:
A new device has been installed.
A device has been moved to a different location or cable
connection.
A device has been removed or disconnected from a cable.
A device is failing and is no longer recognized by the
computer as being installed.
An external device is not turned on.
Processor update code has not been installed or cannot be
found.
An invalid checksum is detected in CMOS memory
(nonvolatile RAM).
Action:
1. Verify that all external devices are turned on. External devices
must be turned on before the computer is turned on.
2. Verify that all devices are properly installed and securely
connected.
3. If you added, removed, or changed the location of a device,
you must save the new configuration in the
Configuration/Setup Utility program. Refer to the Important
text box on page 22 for further information and instructions on
saving the configuration.
4. If you added or changed a microprocessor, you must update
system programs. Refer to “Updating System Programs” on
page 39 for instructions.
5. If you did not add, remove, or change the location of a device,
a device is probably failing. Running the diagnostic programs
might isolate the failing device. (See “Diagnostic Programs”
on page 96 for information about diagnostic programs
provided with your computer.)
If the problem cannot be isolated and corrected, have the computer
serviced.
