Refer to the instructions on setting up a 2/4/5.1/ 7.1-channel audio configuration in Chapter 5, "Configuring 2/4/5.1/7.1-Channel Audio.” - 21 - Hardware Installation 1-7 Internal Connectors 20 5 2 19 1) ATX_12V 11) F_AUDIO 2) ATX 12) CD_IN 3) CPU_FAN 13) SPDIF_I 4) SYS_FAN 14) SPDIF_O 5) FDD 15) F_USB1/F_USB2 6) IDE 16) F1_1394 7) SATA2_0/1/2/3 17) COMA 8) PWR_LED 18) CI 9) BATTERY 19) CLR_CMOS 10) F_PANEL 20) PHASE LED A Read the following guidelines before connecting external devices: • First make sure your devices are compliant with the connectors you wish to connect. • Before installing the devices, be sure to turn off the devices and your computer. Unplug the power cord from the power outlet to prevent damage to the devices. • After installing the device and before turning on the computer, make sure the device cable has been securely attached to the connector on the motherboard. GA-EG41MF-US2H Motherboard - 22 - 1/2) ATX_12V/ATX (2x2 12V Power Connector and 2x12 Main Power Connector) With the use of the power connector, the power supply can supply enough stable power to all the components on the motherboard. Before connecting the power connector, first make sure the power supply is turned off and all devices are properly installed. The power connector possesses a foolproof design. Connect the power supply cable to the power connector in the correct orientation. The 12V power connector mainly supplies power to the CPU. If the 12V power connector is not connected, the computer will not start. • To meet expansion requirements, it is recommended that a power supply that can withstand „re high power consumption be used (500W or greater). If a power supply is used that does not provide the required power, the result can lead to an unstable or unbootable system. • The main power connector is compatible with power supplies with 2x10 power connectors. When using a 2x12 power supply, remove the protective cover from the main power connector on the motherboard. Do not insert the power supply cable into pins under the protective cover when using a 2x10 power supply. □ l-J □ LJ Pin No. Definition 1 GND 2 GND 3 +12V 4 +12V 4 2 a □ I D 0 □ [ D □ □ 0 □ 0 I D □ 0 I D 0 □ □ 0 Pin No. Definition Pin No. Definition 1 3.3V 13 3.3V 2 3.3V 14 -12V 3 GND 15 GND 4 +5V 16 PS_ON (soft On/Off) 5 GND 17 GND 6 +5V 18 GND 7 GND 19 GND 8 Power Good 20 -5V 9 5VSB (stand by +5V) 21 +5V 10 +12V 22 +5V 11 +12V (Only for 2x12-pin ATX) 23 +5V (Only for 2x12-pin ATX) 12 3.3V (Only for 2x12-pinATX) 24 GND (Only tor 2x12-pin ATX) 24 13 ATX - 23 - Hardware Installation 3/4) CPU_FAN/SYS_FAN (Fan Headers) The motherboard has a 4-pin CPU fan header and a 4-pin system fan header (CPU_FAN/ SYS_FAN). Most fan headers possess a foolproof insertion design. When connecting a fan cable, be sure to connect it in the correct orientation (the black connector wire is the ground wire). The motherboard supports CPU fan speed control, which requires the use of a CPU fan with fan speed control design. For optimum heat dissipation, it is recommended that a system fan be installed inside the chassis.

Overheating may result in damage to the CPU or the system may hang. • These fan headers are not configuration jumper blocks. Do not place a jumper cap on the headers. FDD (Floppy Disk Drive Connector) This connector is used to connect a floppy disk drive. The types of floppy disk drives supported are: 360 KB, 720 KB, 1.2 MB, 1.44 MB, and 2.88 MB. Before connecting a floppy disk drive, be sure to locate pin 1 of the connector and the floppy disk drive cable. The pin 1 of the cable is typically designated by a stripe of different color. For purchasing the optional floppy disk drive cable, please contact the local dealer. 33 34 2 GA-EG41MF-US2H Motherboard - 24 - IDE (IDE Connector) The IDE connector supports up to two IDE devices such as hard drives and optical drives. Before attaching the IDE cable, locate the foolproof groove on the connector. If you wish to connect two IDE devices, remember to set the jumpers and the cabling according to the role of the IDE devices (for example, master or slave). (For information about configuring master/slave settings for the IDE devices, read the instructions from the device manufacturers.) 40 39 7) SATA2_0/1/2/3 (SATA 3Gb/s Connectors) The SATA connectors conform to SATA 3Gb/s standard and are compatible with SATA 1.5Gb/s standard. Each SATA connector supports a single SATA device. 7[F 1 1 SATA2_3 £f]7 1^1 Hji Pin No. Definition 1 GND 2 TXP 3 TXN 4 GND 5 RXN 6 RXP 7 GND Please connect the L-shaped end of the SATA 3Gb/s cable to your SATA hard drive. - 25 - Hardware Installation 8...
