ATX PS/2 Keyboard and PS/2 Mouse
Ports
The ATX PS/2 keyboard and PS/2 mouse are
located next to the Back Panel USB Ports on
the motherboard. See the table at right for
pin definitions.
SGPIO
The T-SGPIO1/T-SGPIO2 (Serial General
Purpose Input/Output) headers provide a
bus between the SATA controller and the
backpane to provide SATA enclosure man-
agement functions. Connect the appropriate
cable from the backplane to the T-SGPIO1
header to utilize SATA management func-
tions on your system.
Likewise, the 6-SGPIO1/6-SGPIO2 headers
provide the same function between the SAS
controller and the backpane, and have the
same pin definitions.
Power LED/Speaker
On the JD1 header, pins 1~3 are used for
power LED indication, and pins 4-7 are for
the speaker. See the tables on the right for
pin definitions. If you wish to use the onboard
speaker, you should close pins 6~7 with a
jumper. Connect a cable to pins 4~7 of JD1
to use an external speaker.
