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 operator 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.
