User Manual

When the computer emits a flash code, write it down on a copy of the Diagnostics Checklist and then look up its cause and meaning in Table 2. If
you are unable to resolve the problem, use the Dell Diagnostics to identify a more serious cause. If you are still unable to resolve the problem, call
Dell for technical assistance.
Table 2. Flash Codes and Corrective Actions
Avoiding Interrupt Assignment Conflicts
Problems can arise if two devices attempt to use the same interrupt request (IRQ) line. To avoid this type of conflict, check the documentation for
the default IRQ line setting for each installed device. Then consult Table 3 to configure the device for one of the available IRQ lines.
