optional memory riser boards and use eight 512-MB modules that each have
a maximum of 16 memory devices. See "Memory Module Label" for the

devices it contains. You can also determine the number of memory devices
installed through the System Memory option in system setup.

and Windows® 2000 will be slightly less than 4 GB, depending on the system
configuration.
