[. . . ] All IRQs used by onboard I/O are configured as [Available]. If all IRQs are set to [Reserved], and IRQ 14/15 are allocated to the onboard PCI IDE, IRQ 9 will still be available for PCI and PnP devices. Important IRQ (Interrupt Request) lines are system resources allocated to I/O devices. When an I/O device needs to gain attention of the operating system, it signals this by causing an IRQ to occur. After receiving the signal, when the operating system is ready, the system will interrupt itself and perform the service required by the I/O device. 3-17 M S-7392 M ainboard H/W Monitor Chassis Intrusion The field enables or disables the feature of recording the chassis intrusion status and issuing a warning message if the chassis is once opened. To clear the warning message, set the field to [Reset]. The setting of the field will automatically return to [Enabled] later. CPU Smart FAN Target The mainboard provides the Smart Fan function which can control the CPU fan speed automatically depending on the current temperature to keep it with in a specific range. If the current CPU fan temperature reaches to the target value, the smart fan function will be activated. It provides several sections to speed up for cooling down automaticlly. CPU Min. FAN Speed (%) This field is used to set the minimum CPU fan speed. SYS FAN1 Control The field allows you to determine whether the system fan connected to SYSFAN1 will work or not when the system is turned on. PC Health Status CPU/ System Temperature, CPU FAN/ SYS FAN1/ 2 Speed, CPU Vcore, 3. 3V, 5V, 12V These items display the current status of all of the monitored hardware devices/ components such as CPU voltage, temperatures and all fans' speeds. 3-18 BIOS Setup Frequency/Voltage Control Important Change these settings only if you are familiar with the chipset. Current CPU / DRAM Frequency These items show the current clocks of CPU and Memory speed. (Dynamic Overclocking Technology) is the automatic overclocking function, included in the MSITM 's newly developed CoreCell TM Technology. It is designed to detect the load balance of CPU while running programs, and to adjust the best CPU frequency automatically. W hen the motherboard detects CPU is running programs, it will speed up CPU automatically to make the program run smoothly and faster. W hen the CPU is temporarily suspending or staying in the low load balance, it will restore the default settings instead. Usually the Dynamic Overclocking Technology will be powered only when users' PC need to run huge amount of data like 3D games or the video process, and the CPU frequency need to be boosted up to enhance the overall performance. Settings are: [Disabled] Disable Dynamic Overclocking. [Private] 1st level of overclocking, increasing the frequency by 1%. [Sergeant] 2nd level of overclocking, increasing the frequency by 3%. 3-19 M S-7392 M ainboard [Captain] [Colonel] [General] [Commander] 3rd 4th 5th 6th level of level of level of level of overclocking, increasing overclocking, increasing overclocking, increasing overclocking, increasing the frequency by 5%. the frequency by 15%. Important Even though the Dynamic Overclocking Technology is more stable than manual overclocking, basically, it is still risky.

C-19 M S-7392 M ainboard (4) Specify Volume Size Specify the amount of available array space to be used by the new RAID volume. You may enter the amount in the space or use the slider to specify. It is recommended you use 100% of the available space for the optimized usage. [. . . ]
