1 Motherboard Description
1.1 Overview
The JN440BX motherboard is a versatile platform that offers a wide variety of features. Some of
the options, however, are implemented – at least in part – on the riser. Throughout this manual,
the ‡ symbol is used to indicate such an option. Because there is no standard riser, no detailed
description of an implementation can be given. See Section 6.1 to obtain the reference design for
the NLX riser.
