Table 1. Boot Routine Indications
System Setup
You can easily correct certain system problems by verifying the correct settings in System Setup . When you boot your system, your system checks
the system configuration information and compares it with the current hardware configuration. If your system hardware configuration does not
match the information recorded by System Setup, an error message may appear on your screen.
This problem can happen if you changed your system's hardware configuration and forgot to run System Setup. To correct this problem, enter
System Setup, correct the setting for the corresponding System Setup program option, and reboot your system.
If after checking the settings in System Setup you have not resolved the problem, see " Dell Diagnostics ."
