[. . . ] The available IRQ pool is determined by reading the ESCD NVRAM. If more IRQs must be removed from the IRQ pool, the end user can use these settings to reserve the IRQ by assigning an [Reserved] setting to it. 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-7395 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 . SYS FAN1 Control This item allows users to select how percentage of speed for the SYS FAN1. PC Health Status CPU/ System Temperature, CPU FAN/ SYS FAN1 Speed, CPU Vcore, 3. 3V, 5V, 12V, 5V SB 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 USER SETTINGS Save Settings 1/2 Select this item and press "Enter" to save any changes you have made to your current settings. Load Settings 1/2 Select this item and press "Enter" to load settings from the store. 3-19 M S-7395 M ainboard Cell Menu 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. D. O. T Control This item allows users to enable/disable the D. O. T. (Dynamic Overclocking Technology) is an automatic overclocking function, included in the MSI TM 's newly developed Dual CoreCellTM Technology. It is designed to detect the load balance of CPU while running programs, and to adjust the best frequency automatically. W hen the motherboard detects system is running programs, it will speed up automatically to make the program run smoothly and faster. W hen the system 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. 3-20 BIOS Setup Important Even though the Dynamic Overclocking Technology is more stable than manual overclocking, basically, it is still risky. [. . . ] From W indows Vista/XP/2000, open the Control Panel from My Computer followed by the System icon. Choose the Hardware tab, then click the Device M anager tab. Click the "+" in front of the SCSI and RAID Controllers hardware type. The driver JMicron JM B36X Controller should appear. C-12 JMicron RAID JMicron Raid Configurer There is an application called JMRaidTool which helps you perform the following tasks of JMicron RAID. [. . . ]
