Jumpers and Connectors

Connectors on the AIMB-273 motherboard link it to devices such as hard disk drives
and a keyboard. In addition, the board has a number of jumpers used to configure
your system for your application.
The tables below list the function of each of the board jumpers and connectors. Later
sections in this chapter give instructions on setting jumpers. Chapter 2 gives instruc-
tions for connecting external devices to your motherboard.
