Setting the Jumpers
The illustration below shows the locations of jumpers
J1 through J6 on the main system board. Check the table

L option slot 4
Jumpers J1 through J5 are located in the lower front corner of
the main system board. Jumper J6 is located above option slot
number 4, just to the left of the SIMM sockets.
To move a jumper from one position to the other, use needle-
nose pliers or tweezers to pull it off its current pins and gently
move it to the other position. Be careful not to lose the jumper
or leave it out of the computer. Also take care not to damage
the jumper pins or any surrounding components on the main
system board.
