Board Installation
1-H Hardware Reset Switch Connector Installation
The Reset switch on your cases display panel provides you with the Hard-
ware Reset function, which is the same as power on/off. The system will do a
cold start after the Reset button is pushed. (J1 pin 5 & 7)
1-I Onboard Sound audio Connectors (Video-In and CD-IN)
There are two 4-pin connectors onboard which are used for various peripher-
als audio signals. The digital signal that comes in through these connectors is
directed through the VIA KX-133 onboard sound function, and the digital
signal is turned into an audio signal which goes out through the speaker. This
consists of the VIDEO-IN connector for DVD drives and the CD-IN connector
is for CD-ROMs.
1-M. USB Header (Jumper
J2)
The Southbridge of the KX-133
chipset is capable of handling 4
USB ports. Only 2 connectors are
provided on the motherboard. If
you need to use all four ports, a
USB header (J2) is provided should
you decide to set up a USB
connector externally.
1-K Power LED Connector
(Jumper JP22)
Jumper JP22 is a three pin power LED header that can be used if you have a 3
pin Power LED. Otherwise refer to panel connector J16 for 2 pin LEDs. 3 pin
LEDs can still be used on J1 where pin 13 would be for the Ground pin.
Suspend to RAM ACPI Enable/Disable (Jumper JP18)
This jumper controls the ACPI advanced power management function . Set
the jumper JP18 to 1-2 to enable ACPI or set the jumper to 2-3 to turn the ACPI
function off. Default is OFF (2-3). ACPI must also be enabled in the BIOS in
order for this function to be activated. If ACPI is not enabled, the Sleep
Button (Jumper J24) will not function.
