I/O Shield Connector
The board is equipped with an I/O back panel. Please use the appropriate I/O shield
(figure 3).
Power-On/Off (Remote)
The board has a single 20-pin and 4-pin connector for ATX or ATX12V power
supplies (Figure 4). For ATX or ATX12V power supplies that support the Remote
On/Off feature, this should be connected to the mainboard front panel PW_ON
connector for the computer power On/Off button.
The board has been designed with Soft Off" function. You can turn off the system
two ways: pressing the front panel power On/Off button, using the "Soft Off"
function (incorporated in the mainboards onboard circuit controller) that can be
controlled by an operating system such as Windows
®
ME/2000/98/95.
Note: For maintaining the DDR SDRAM power during STR (ACPI S3) function, it is
strongly recommend to use ATX or ATX12V power supplies that have a +5VSB
current of (>=) 1A (1000mA). Please check the 5VSBs specification that has been
printed on the ATX or ATX12V power supplys outer case.
Note: The board requires a minimum of 250 Watt ATX or ATX 12V power supply to
operate. Your system configuration (amount of memory, add-in cards, peripherals,
etc.) may exceed the minimum power requirement but to ensure that adequate
power is provided, use a 300 Watt (or greater) ATX or ATX 12V power supply.
