Step 3.

Firmly insert the DIMM into the slot until the retaining clips at both ends fully snap back in place and the DIMM is properly seated.
Expansion Slots (PCI and PCI Express Slots)
There are 2 PCI slots and 2 PCI Express slots on 939S56-M motherboard. PCI Slots: PCI slots are used to install expansion cards that have the 32-bit PCI interface. PCIE Slots: PCIE1 (PCIE x16 slot) is used for PCI Express cards with x16 lane width graphics cards. PCIE2 (PCIE x1 slot) is used for PCI Express cards, such as Gigabit LAN card, SATA II card, etc.
Installing an expansion card
Step 1. Before installing the expansion card, please make sure that the power supply is switched off or the power cord is unplugged. Please read the documentation of the expansion card and make necessary hardware settings for the card before you start the installation. Remove the system unit cover (if your motherboard is already installed in a chassis). Remove the bracket facing the slot that you intend to use. Keep the screws for later use. Align the card connector with the slot and press firmly until the card is completely seated on the slot. Fasten the card to the chassis with screws. Replace the system cover.
Step 2. Step 3. Step 4. Step 5. Step 6.

Jumpers Setup

(see p.8, No. 1)

Setting

1_2 2_3

Short pin2, pin3 to enable +5VSB (standby) for PS/2 or +5V +5VSB USB wake up events. Note: To select +5VSB, it requires 2 Amp and higher standby current provided by power supply. JR1JL1 Jumper

(see p.8, No. 24)

Note: If the jumpers JL1 and JR1 are short, both the front panel and the rear panel audio connectors can work. Clear CMOS Jumper
(CLRCMOS2) (see p.8, No. 18)
Note: CLRCMOS2 allows you to clear the data in CMOS. The data in CMOS includes system setup information such as system password, date, time, and system setup parameters. To clear and reset the system parameters to default setup, please turn off the computer and unplug the power cord from the power supply. After waiting for 15 seconds, use a jumper cap to short 2 pins on CLRCMOS2 for 5 seconds. However, please do not clear the CMOS right after you update the BIOS. If you need to clear the CMOS when you just finish updating the BIOS, you must boot up the system first, and then shut it down before you do the clear-CMOS action.

AT (SAT Serial ATA (SATA) Hard Disks Installation
This motherboard supports Serial ATA (SATA) hard disks and RAID functions. This section will guide you to install the SATA hard disks. STEP 1: Install the SATA hard disks into the drive bays of your chassis. STEP 2: Connect the SATA power cable to the SATA hard disk. STEP 3: Connect one end of the SATA data cable to the motherboards SATA connector. STEP 4: Connect the other end of the SATA data cable to the SATA hard disk.

1. If you plan to use RAID 0, RAID 1, or JBOD functions on SATA, SATA HDDs must be operated in RAID mode. 2. RAID and non-RAID mode are options under SATA Operation Mode in BIOS setup. Please refer to page 28 for details. They need different drivers during actual operation.
Function SAT Hot Plug Function for SATA HDDs
939S56-M motherboard supports Hot Plug function for SATA devices. What is Hot Plug Function?
If the SATA HDDs are NOT set for RAID configuration, it is called Hot Plug for the action to insert and remove the SATA HDDs while the system is still power-on and in working condition. However, please note that it cannot perform Hot Plug if the OS has been installed into the SATA HDD.

WARNING!

Although this motherboard supports Hot Plug function for SATA devices, there are still some limitation. Please ensure to read the instruction in the Support CD before you use Hot Plug function. Failure to do so may lose the data in the SATA HDDs or damage the SATA HDDs. For the detailed instruction, please refer to the document in the Support CD at the following path:.\ RAID BIOS Setting Utility
SAT Diskette For SAT Making a SATA Driver Diskette For SATA Operation in RAID Mode
If you want to install Windows 2000, Windows XP, or Windows XP 64-bit OS on your SATA HDDs with RAID functions, you will need to make a SATA driver before you start the OS installation. STEP 1: Insert the ASRock Support CD into your optical drive to boot your system. (Do NOT insert any floppy diskette into the floppy drive at this moment!) STEP 2: During POST at the beginning of system boot-up, press <F11> key, and then a window for boot devices selection appears. Please select CDROM as the boot device. STEP 3: When you see the message on the screen, Do you want to generate Serial ATA driver diskette [YN]?, press <Y>. STEP 4: Then you will see these messages, Please insert a diskette into the floppy drive. WARNING! Formatting the floppy diskette will lose ALL data in it! Start to format and copy files [YN]? Please insert a floppy diskette into the floppy drive, and press <Y>. STEP 5: The system will start to format the floppy diskette and copy SATA drivers into the floppy diskette.

Once you have the SATA driver diskette ready, you may start to install Windows 2000 / Windows XP / Windows XP 64-bit on your system directly without setting the RAID configuration on your system, or you may start to use SiS RAID BIOS Setting Utility to set RAID 0 / RAID 1 / JBOD configuration before you install the OS. Before you start to configure the RAID function, you need to check the installation guide in the Support CD for proper configuration. Please find the document, Guide to SATA Hard Disks Installation and RAID Configuration, at the following path in the Support CD:. \ RAID BIOS Setting Utility You may also set the RAID configuration by using SiS RAID Utility for Windows in Windows environment.

CAUTION!

1. For power-saving sake, it is strongly recommended to enable AMDs Cool n QuietTM technology under Windows system. See APPENDIX on page 37 of User Manual in the support CD to enable AMDs Cool n QuietTM technology. This motherboard supports Untied Overclocking Technology. FSB enjoys better margin due to fixed PCI/PCIE buses. In other words, CPU FSB is untied during overclocking, but PCIE and PCI buses are in the fixed mode so that FSB can operate under a more stable overclocking environment. While CPU overheat is detected, the system will automatically shutdown. Before you resume the system, please check if the CPU fan on the motherboard functions properly and unplug the power cord, then plug it back again. To improve heat dissipation, remember to spray thermal grease between the CPU and the heatsink when you install the PC system. Power Management for USB 2.0 works fine under Microsoft Windows XP SP1 / 2000 SP4. It may not work properly under Microsoft Windows 98/ ME. For microphone input, this motherboard supports both stereo and mono modes. For audio output, this motherboard supports 2-channel, 4-channel, 6-channel, and 8-channel modes. Please check the table on page 3 for proper connection. Although this motherboard offers stepless control, it is not recommended to perform over-clocking. Frequencies other than the recommended CPU bus frequencies may cause the instability of the system or damage the CPU.

2. Installation
Pre-installation Precautions
Take note of the following precautions before you install motherboard components or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any component. Failure to do so may cause severe damage to the motherboard, peripherals, and/or components. To avoid damaging the motherboard components due to static electricity, NEVER place your motherboard directly on the carpet or the like. Also remember to use a grounded wrist strap or touch a safety grounded object before you handle components. Hold components by the edges and do not touch the ICs. Whenever you uninstall any component, place it on a grounded antstatic pad or in the bag that comes with the component. When placing screws into the screw holes to secure the motherboard to the chassis, please do not over-tighten the screws! Doing so may damage the motherboard.

Step 1. Step 2. Step 3.

CPU Installation
Unlock the socket by lifting the lever up to a 90 angle. Position the CPU directly above the socket such that its marked corner matches the base of the socket lever. Carefully insert the CPU into the socket until it fits in place.
The CPU fits only in one correct orientation. DO NOT force the CPU into the socket to avoid bending of the pins.

Step 4.

Step 5.
When the CPU is in place, press it firmly on the socket while you push down the socket lever to secure the CPU. The lever clicks on the side tab to indicate that it is locked. Install CPU fan and heatsink. For proper installation, please kindly refer to the instruction manuals of your CPU fan and heatsink vendors.
2.2 Installation of Memory Modules (DIMM)
939S56-M motherboard provides four 184-pin DDR (Double Data Rate) DIMM slots, and supports Dual Channel Memory Technology. For dual channel configuration, you always need to install identical (the same brand, speed, size and chip-type) DDR DIMM pair in the slots of the same color. In other words, you have to install identical DDR DIMM pair in Dual Channel A (DDR1 and DDR2; Blue slots; see p.2 No. 5) or identical DDR DIMM pair in Dual Channel B (DDR3 and DDR4; Black slots; see p.2 No. 6), so that Dual Channel Memory Technology can be activated. This motherboard also allows you to install four DDR DIMMs for dual channel configuration, and please install identical DDR DIMMs in all four slots. You may refer to the Dual Channel Memory Configuration Table below. Dual Channel Memory Configurations DDR1 (Blue Slot) Populated Populated DDR2 (Blue Slot) Populated Populated DDR3 (Black Slot) Populated Populated DDR4 (Black Slot) Populated Populated

(1) (2) (3)*

* For the configuration (3), please install identical DDR DIMMs in all four slots. * It is recommended to install DDR1 and DDR2 (blue slots) first. Then to install
in DDR3 and DDR4 (black slots). (That is, to populate DDR DIMM from the near side of CPU towards to the far side of CPU.)
If you want to install two different memory modules, for optimal compatibility and reliability, it is recommended to install them in the slots of different color. In other words, install them either in DDR1 and DDR3. If only one memory module or three memory modules are installed in the DDR DIMM slots on this motherboard, it is unable to activate the Dual Channel Memory Technology. If a pair of memory modules is NOT installed in the same Dual Channel, for example, installing a pair of memory modules in DDR1 and DDR3, it is unable to activate the Dual Channel Memory Technology.

Installing a DIMM

Please make sure to disconnect power supply before adding or removing DIMMs or the system components.

STEP 1: STEP 2:

Unlock a DIMM slot by pressing the retaining clips outward. Align a DIMM on the slot such that the notch on the DIMM matches the break on the slot.
The DIMM only fits in one correct orientation. It will cause permanent damage to the motherboard and the DIMM if you force the DIMM into the slot at incorrect orientation.

STEP 3:

Firmly insert the DIMM into the slot until the retaining clips at both ends fully snap back in place and the DIMM is properly seated.
2.3 Expansion Slots (PCI and AGP Slots)
There are 2 PCI slots and 2 PCI Express slots on 939S56-M motherboard. PCI Slots: PCI slots are used to install expansion cards that have the 32-bit PCI interface. PCIE Slots: PCIE1 (PCIE x16 slot) is used for PCI Express cards with x16 lane width graphics cards. PCIE2 (PCIE x1 slot) is used for PCI Express cards, such as Gigabit LAN card, SATA II card, etc.
Installing an expansion card
Step 1. Before installing the expansion card, please make sure that the power supply is switched off or the power cord is unplugged. Please read the documentation of the expansion card and make necessary hardware settings for the card before you start the installation. Remove the bracket facing the slot that you intend to use. Keep the screw for later use. Align the card connector with the slot and press firmly until the card is completely seated on the slot. Fasten the card to the chassis with screws.
