ystem Error Messages
System error messages typically are presented on the screen during the POST
but can occur any time an error is detected by the system. System messages are
very useful in troubleshooting the system. Some of these messages require oper-
ator intervention to solve; others indicate fatal errors that must be solved before
the system will reboot.
Table 3-2 lists the system error messages that can occur and the probable cause
for each message.
