4: Maintenance, Service & Troubleshooting
Error Messages During Start-up
If a non-fatal error is detected during start-up (i.e. an error which
does not prevent the system from starting up), an error message is
displayed on your screen. Note the error message and then press
<F1> to continue. This section lists some of the error messages which
are displayed and suggests how to correct the error using the Setup
program. There may also be some error message codes in the
System board User Manual
(if supplied).
If an error message is displayed on the screen, which is not listed,
contact RM for further information on the error which has been
detected.
If the POST (Power On Self Tests) detect a fatal error during start-up
(i.e. an error which will not allow the system to continue the start-up
procedure), your computer has developed a serious problem and you
should contact RM for assistance. Fatal errors are usually
communicated through a series of audible beeps. Note, however, that
some computers always beep when the BIOS System Configuration
screen is displayed to signal that the POST routines are finished.
Cache Memory Bad, Do Not Enable Cache!
The external cache memory is defective.
CMOS Battery State Low
The battery in your system, which provides power to CMOS to store
the system settings, is low in power and needs to be changed or
recharged (depending on the battery type). Leave the computer
switched on for 48 hours to recharge the battery.
CMOS Checksum Failure
When you save changes made in Setup and exit the Setup program, a
checksum value is generated. This value is stored and used for error
checking. If this stored value is different from the value determined by
the POST routines during start-up, the CMOS Checksum Failure error
message is displayed. Change the Setup to the optimal settings then
change any additional variances according to the model of computer
(see page 61 for details on the Setup program). If this error message
is displayed frequently, you may have a hardware problem and should
contact RM.
