Table 2-3 lists the main functions that are controlled by the contents of the nonvolatile
Configuration Memory.

As shipped from the factory, the Little Board/386 can be booted from a bootable DOS diskette in
a 5-1/4" 360K byte floppy drive. You can use the "hot-key" entry into SETUP to set system
parameters prior to boot. Using SETUP, you can also load system setup parameters from a disk
file, which is useful when configuring systems in a production environment. Refer to Chapter 3
and Appendix A for detailed information on the functions and use of SETUP which is used to
initialize these parameters in the board's nonvolatile Configuration Memory devices.
2.2 DC POWER INPUT
The power connector, J1, has a pinout which is identical with that of power connectors on nearly
all 5-1/4 inch disk drives, except that only the +5 volt and ground connections are used. Note
that pin 1 on J1 is reversed from that of the header connectors on the Little Board/286. Refer to
Table 2-4 for power connections and mating connector information, and Figure 2-2 for typical
connector wiring.
Caution
Be sure the power plug is correctly wired before applying
power to the board! See figure 2-2.
