Jumpers and Connectors

Connectors on the ASMB-587 motherboard link it to external devices such as hard
disk drives and a keyboard. In addition, the board has a number of jumpers that are
used to configure your system for your application.
The tables below lists the functions of each of the jumpers and connectors. Later sec-
tions in this chapter give instructions on setting jumpers. Chapter 2 gives instructions
for connecting external devices to your motherboard.
