Note 2 : Due to the OS limitations, some operating systems may not show more
than 4 GB of memory.
Note 3 : Due to memory allocation to system devices, memory remaining avail-
able for operational use will be reduced when 4 GB of RAM is used. The reduction
in memory availability is disproportional. *Refer to the Memory Availability Table
