Jumpers and Connectors
The AIMB-U217 motherboard is equipped with connectors for linking the board to
external devices such as hard disk drives. The board also features several jumpers
for configuring the system according to specific applications.
The function of each board jumper and connector is listed in the table below. The pro-
cedure for setting jumpers is explained in subsequent sections of this chapter.
Instructions for connecting external devices to the motherboard are provided in
Chapter 2.
