System Beep Codes
When errors occur during a boot routine that cannot be reported on the monitor, the computer may emit a series of beeps that identify the problem. The beep code is a pat- tern of beeps. For example, four beeps means the timer is not operational. This information is valuable to the Dell support staff if you need to call for technical assistance.
When a beep code is emitted, write it down on a copy of the Diagnostics Checklist found in Appendix A, and then look it up in Table

Warning Messages
A warning message alerts you to a possible problem and asks you to do something before execution continues. For example, before you format a diskette, a message may warn you that you may lose all data on the diskette as a way to protect against inadvertently erasing or writing over the data. These warning messages usually interrupt the procedure and require you to respond by typing a y (yes) or n (no).
NOTE: Warning messages are generated by either the application programs or the operating system. See Chapter 4, “Finding Software Solutions,” and the docu- mentation that accompanied the operating system and application programs.
