1.3.2 Value-added solutions Temperature, fan, and voltage monitoring The CPU temperature is monitored by the ASUS ASIC to prevent overheating and damage. The system fan rotations per minute (RPM) is monitored for timely failure detection. The system voltage levels are monitored to ensure stable supply of current for critical components. Dual function power switch While the system is ON, pressing the power switch for less than 4 seconds puts the system to sleep mode or to soft-off mode, depending on the BIOS setting. Pressing the power switch for more than 4 seconds lets the system enter the soft-off mode regardless of the BIOS setting. Wake-Up support The motherboard includes Wake-On-LAN, Wake-On-Ring, and BIOS Wake-Up features. ACPI ready The Advanced Configuration power Interface (ACPI) provides more energy saving features for operating systems that support OS Direct Power Management (OSPM). Concurrent PCI This feature allows multiple PCI transfers from PCI master buses to the memory and processor. Chassis intrusion detection With this feature, the chassis intrusion circuitry logs "chassis-open" events into the system BIOS. The onboard battery supports the chassis intrusion detection feature even when the normal power is removed. Smart BIOS The 4Mbit firmware hub (FWH) gives an easy-to-use interface that provides more control and protection to the motherboard. The BIOS has a boot block write protection and HD/SCSI/MO/ZIP/CD/Floppy boot selection, and is Year 2000 certified. 1-4 Chapter 1: Product introduction
