MS-9834 CPU (Central Processing Unit) When you are installing the CPU, make sure that you install the cooler to prevent overheating. If you do not have the CPU cooler, consult your dealer before turning on the computer. Important Overheating Overheating will seriously damage the CPU and system. Always make sure the cooling fan can work properly to protect the CPU from overheating.
▍ Hardware setup CPU Installation 1. Locate the CPU socket on the mainboard. On the upper end of the CPU socket is a socket actuator in the form of a slotted screw head. Make sure that you open or close the socket with a flathead screwdriver before and after installing the CPU. 2. Turn the socket actuator counterclockwise to open the socket. Locate the golden arrow on the CPU and align it to the upper right corner of the socket. Put the CPU gently down.
MS-9834 Memory These DIMM slots are intended for memory modules. DDR2 SO-DIMM Slot 200-pin, 1.8V Installing Memory Modules 1. Locate the DIMM1 SO-DIMM slot. Align the notch on the DIMM with the key on the slot and insert the DIMM into the slot at 45-degree angle. 2. Push the DIMM gently forwards until the slot levers click and lock the DIMM in place. Follow the same procedures to install the second DIMM if necessary. 3.

The time format is . ▶ System Date This setting allows you to set the system date. The date format is , .
▍ BIOS SETUP Advanced ▶ CPU Configuration 3-6
MS-9834 ▶ Hardware Prefetcher The processor has a hardware prefetcher that automatically analyzes its requirements and prefetches data and instructions from the memory into the Level 2 cache that are likely to be required in the near future. This reduces the latency associated with memory reads. When enabled, the processor’s hardware prefetcher will be enabled and allowed to automatically prefetch data and code for the processor. When disabled, the processor’s hardware prefetcher will be disabled.
▍ BIOS SETUP ▶ Core Multi-Processing CMP (Core Multi Processing) is the ability to have many independent processing cores on a single die, each with their own L1 Code & Data caches, Local APICs & thermal controls, while having a shared L2 cache, power management & bus interface.
MS-9834 ▶ Primary/Secondary/Third/Fourth IDE Master [Type] Press PgUp/<+> or PgDn/<-> to select [Manual], [None] or [Auto] type. Note that the specifications of your drive must match with the drive table. The hard disk will not work properly if you enter improper information for this category. If your hard disk drive type is not matched or listed, you can use [Manual] to define your own drive type manually.
▍ BIOS SETUP ▶ Hardware Health Configuration These items display the current status of all monitored hardware devices/components such as voltages, temperatures and all fans’ speeds. ▶ H/W Health Function This setting enables/disables the hardware monitor function. ▶ 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].
MS-9834 ▶ ACPI Configuration ▶ Suspend Mode This item specifies the power saving modes for ACPI function. If your operating system supports ACPI, you can choose to enter the Standby mode in S1 (POS) or S3 (STR) fashion through the setting of this field. ▶ USB Device Wakeup From S3 This setting allows the activity of the USB device to wake up the system from the S3 sleep state.
▍ BIOS SETUP ▶ APM Configuration ▶ Restore on AC Power Loss This setting specifies whether your system will reboot after a power failure or interrupt occurs. Available settings are: [Power Off] Leaves the computer in the power off state. [Power On] Leaves the computer in the power on state.

TPMs are special-purpose integrated circuits (ICs) built into a variety of platforms to enable strong user authentication and machine attestation -- ssential to prevent inappropriate access to confidential and sensitive information and to protect against compromised networks.
MS-9834 Boot ▶ Boot Settings Configuration ▶ Quick Boot Enabling this setting will cause the BIOS power-on self test routine to skip some of its tests during bootup for faster system boot.
▍ BIOS SETUP ▶ Quiet Boot This BIOS feature determines if the BIOS should hide the normal POST messages with the motherboard or system manufacturer’s full-screen logo. When it is enabled, the BIOS will display the full-screen logo during the boot-up sequence, hiding normal POST messages. When it is disabled, the BIOS will display the normal POST messages, instead of the full-screen logo. Please note that enabling this BIOS feature often adds 2-3 seconds of delay to the booting sequence.
MS-9834 ▶ Boot Device Priority The items allow you to set the sequence of boot devices where BIOS attempts to load the disk operating system. First press to enter the sub-menu. Then you may use the arrow keys ( ↑↓ ) to select the desired device, then press <+>, <-> or , key to move it up/down in the priority list. ▶ Removable Drives This setting allows users to set the priority of the removable devices. First press to enter the sub-menu.
▍ BIOS SETUP Security ▶ Supervisor Password / Change Supervisor Password Supervisor Password controls access to the BIOS Setup utility. These settings allow you to set or change the supervisor password. ▶ User Password / Change User Password User Password controls access to the system at boot. These settings allow you to set or change the user password.
MS-9834 Chipset ▶ North Bridge Configuration ▶ DVMT Mode Select Intel’s Dynamic Video Memory Technology (DVMT) allows the system to dy3-21
▍ BIOS SETUP namically allocate memory resources according to the demands of the system at any point in time. The key idea in DVMT is to improve the efficiency of the memory allocated to either system or graphics processor. It is recommended that you set this BIOS feature to DVMT Mode for maximum performance. Setting it to DVMT Mode ensures that system memory is dynamically allocated for optimal balance between graphics and system performance.
MS-9834 ▶ GbE Controller This setting disables/enables the onboard Gigabit Ethernet controller. ▶ GbE LAN Boot When [Enabled], the BIOS attempts to boot from a LAN boot image before it attempts to boot from a local storage device. ▶ GbE Wake Up From S5 This field specifies whether the system will be awakened from the S5 power saving mode when activity or input signal of onboard LAN is detected. ▶ HDA Controller This setting controls the High Definition Audio interface integrated in the Southbridge.
▍ BIOS SETUP Exit ▶ Save Changes and Exit Save changes to CMOS and exit the Setup Utility. ▶ Discard Changes and Exit Abandon all changes and exit the Setup Utility. ▶ Discard Changes Abandon all changes and continue with the Setup Utility. ▶ Load Optimal Defaults Use this menu to load the default values set by the mainboard manufacturer specifically for optimal performance of the mainboard.
