2-3 Jumper Options and Connectors
After the switches are set correctly, other attachments and jumper
option adjustments on the mainboard have to be made. See the
illustration on page 4 for the location of the jumpers and connectors.
The jumpers have been preset at the factory, but not necessarily for
the system configuration you want.
Jumpers
A jumper is a kind of switch which uses a plastic cap with a metal
interior to connect (short) two pins. If a jumper needs to be left open,
you should save the cap for future use by covering only one pin of the
jumper. This has no effect on the function of the board while it keeps
the cap handy. The illustration below shows the side and top views of
a three-pin jumper in which pins two and three are shorted.
