2. The electrical outlet functions properly.
3. The type of memory installed is correct.

it is used only by the integrated ASM Processor, and is not available for use by
the operating system. This port does not appear in the Configuration/Setup
Utility program menus; it can be configured using your system-management
software.
2. The serial-port adapter, if you installed one, is seated properly.
