1 Introduction 1.1.3 Intelligence CPU Fan Protection The CPU Fan Protection function has the capability of monitoring the CPU fan when the system boots. Once it has detected that the CPU fan did not rotate, 5 warning beeps will sound then the system will automatically power-off. This preventive measure has been added to protect the CPU from damage and insure a safe computing environ- ment. CPU Temperature Protection The CPU Temperature Protection function has the capability of monitoring the CP

1 Introduction Wake-On-LAN This feature allows the network to remotely wake up a Soft Power Down (Soft-Off) PC. It is supported via the onboard LAN port, via a PCI LAN card that uses the PCI PME (Power Management Event) signal or via a LAN card that uses the Wake-On-LAN connector. However, if your system is in the Suspend mode, you can power-on the system only through an IRQ or DMA interrupt. Important: The 5VSB power source of your power supply must support ≥720mA.

ON 1 2 2 Hardware Installation . . . Warning: . . . . . Electrostatic discharge (ESD) can damage your system board, processor, disk drives, add-in boards, and other components. Perform the upgrade instruction procedures described at an ESD workstation only. If such a station is not available, you can provide some ESD protection by wearing an antistatic wrist strap and attaching it to a metal part of the system chassis. If a wrist strap is unavailable, establish and maintain contact with the syst

2 Hardware Installation The system board supports the following memory interface. Single Channel (SC) Data will be accessed in chunks of 64 bits (8B) from the memory channels. Virtual Single Channel (VSC) If both channels are populated with different memory configurations, the MCH defaults to Virtual Single Channel. Dual Channel (DC) Dual channel provides better system performance because it doubles the data transfer rate. Dynamic Mode Addressing This mode minimizes the overhead of opening/closi
