2-3 short: SUS_S3# select
PSON# signal source select
ATXPOW UP
1-2 short: SIO output signal (SIO_PSON#) select
J9
Control Select
2-3 short: Suspend signal from COMe module select (in this
case, using suspend signal is depend on the J7 selection)
IOH_PLA Reset input select
1-2 short: reset assert by D33VA_D33V (IOPLA) Powerup
IOH PLA Reset
3-4 short: reset assert by SIO RSMRST#
J10
Select
5-6 short: reset assert by CB_RESET#
This jumper setting is linked with the IOH_PLA power selection
by J5.

1-2 short: reset assert by SIO RSMRST#
IOH PLB Reset
3-4 short: reset assert by SIO KBDRST#
J11
Select
5-6 short: reset assert by CB_RESET#
This jumper setting is limited by the IOH_PLB power selection
by J6.
connection select between UART0 DTR port of IOH to RS232C
driver
UART0 port
J12
1-2 short: connect to RS232C driver
DTR connection
open: no connection (if the case of using UART0 port in baud
rate up 4Mbps, it is necessary to be set open.)
Note:
A jumper consists of two or more pins mounted on the board. When a jumper cap is placed over two pins, it is
designated as SHORT. When there are more than two pins on the jumper, the pins to be shorted are indicated as 1–2 (to
short pin 1 to pin 2), 2–3 (to short pin 2 to pin 3), etc. When no jumper cap is to be placed on the jumper, it is
designated as OPEN.
