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 dispropor-
tional. (See the following Table.)
