Note 1: Due to OS limitations, some operating systems may not show more than
4 GB of memory.
Note 2: Due to memory allocation to system devices, the amount of memory that
remains available for operational use will be reduced when 4 GB of RAM is used.
The reduction in memory availability is disproportional. (See the following Memory
Availability Table.)
