Cathy,

The following is extracted from a scanned manual off a Chinese Web for a
RHINO 12 MainBoard.  Looking from the front of the motherboard, there
should be a CN8 connector located at the bottom left hand corner.  This is
a single line 22-pins connector (but you must also count empty pins
between groups of connectors as pins also.) There are groups of
connector pins:  one-5pins; one-4pins; and four-2pins.  Pin 1 is closest
to the ISA slots.  These are the legends:

     1 = + POWER_LED
     2 = N/C
     3 = GND
     4 = KB_LOCK
     5 = GND

     6 = empty space

     7 = SPKR_OUT
     8 = N/C
     9 = GND
    10 = +5V

    11 = empty space

    12 = RESET_SWITCH
    13 = GND

    14 = empty space

    15 = N/C
    16 = N/C

    17 = empty space

    18 = SUSPEND_SWITCH
    19 = GND

    20 = empty space

    21 = +5V
    22 = HD_LED


If you have difficulty of having the HD_LED lit, you should be able to
reverse the connector to see it lights without any damage because a
reverse biased LED exhibits very high resistance.

HTH,

Patrick
