&& Case Open Displays the detection status of the chassis intrusion detection device attached to the motherboard CI header. If the system chassis cover is removed, this field will show "Open", otherwise it will show "Close." To clear the chassis intrusion status record, set Reset Case Open Status to Enabled, save the settings to the CMOS, and then restart your system. && Reset Case Open Status Disabled Keeps or clears the record of previous chassis intrusion status. (Default) Enabled Clears the record of previous chassis intrusion status and the Case Open field will show "No" at next boot. `` H/W Monitor && CPU Temperature (DTS)/System Temperature Displays current CPU/system temperature. && CPU/System Fan Speed Displays current CPU/system fan speeds. && Vcore/VCC3/+12V/VCC/CPU_VAXG/3VDUAL/DDR1_35VIO Displays the current system voltages. `` CPU Configuration `` Socket 0 CPU Information This section provides information on your CPU, frequency, and cache memory. && Active Processor Cores Allows you to determine whether to enable all CPU cores. (Default: All) && Limit CPUID Maximum Allows you to determine whether to limit CPUID maximum value. Set this item to Disabled for Windows XP operating system; set this item to Enabled for legacy operating system such as Windows NT4.0. (Default: Disabled) && Execute Disable Bit Enables or disables Intel® Execute Disable Bit function. This function may enhance protection for the computer, reducing exposure to viruses and malicious buffer overflow attacks when working with its supporting software and system.

With virtualization, one computer system can function as multiple virtual systems. (Default: Enabled) && Power Technology Allows you to configure Intel® power management features. (Default: Energy Efficient) `` PPM Configuration && EIST Enables or disables Enhanced Intel® Speed Step Technology (EIST). Depending on CPU loading, Intel EIST technology can dynamically and effectively lower the CPU voltage and core frequency to decrease average power consumption and heat production. (Default: Enabled) - 19 -
