Applications, operating systems, and the computer itself are capable of identifying
problems and alerting you to them. When a problem occurs, a message may appear
on the monitor screen or a beep code may sound.
Several different types of messages can indicate when the system is not functioning
properly:
System messages
System beep codes
Warning messages
Diagnostics messages
Alert messages
Small computer system interface (SCSI) hard-disk drive indicator codes
This chapter describes each type of message and lists the possible causes and
actions you can take to resolve any problems indicated by a message. To determine
what type of message you have received, read the following sections.
System messages alert you to a possible operating system problem or to a conflict
between the software and hardware. Table 3-1 lists the system error messages that
can occur and the probable cause for each message.
NOTE: If you receive a system message that is not listed in Table 3-1, check the docu-
mentation for the application that is running when the message appears and/or the
operating system documentation for an explanation of the message and recom-
mended action.
