Jumpers and connectors
Connectors on the board link it to external devices such as hard disk
drives, a keyboard or PC/104 modules. In addition, the board has a
number of jumpers which you use to configure it for your application.
The table below lists the function of each of the board jumpers and
connectors. Later sections in this chapter give instructions on setting
jumpers and detailed information on each jumper setting. Chapter 3

SIMM memory modules
On the left end of the card (away from the mounting bracket) are the
four SIMM (Single In-line Memory Module) sockets which hold the
card’s DRAM memory. If you ordered DRAM SIMMs along with your
card, the SIMMs may already be installed. If not, you should install
them as described in Appendix B.
