4.2 CPU Installation |
|
|
|
This main board has a socket 478 processor socket. Follow these instructions to install the CPU:
1.Unhook the CPU socket’s locking lever pulling it away from socket and raising it to the upright position.
2.Match the pin 1 corner of CPU socket to the one of processor, and insert the processor into the socket. Do not use force.
3.Push the locking lever down and hook it under the latch on the edge of socket.
4.Apply thermal grease to the top of the CPU.
5.Lower the CPU fan/heat sink unit onto the CPU and CPU socket, and then use the retention module clamps to snap the fan/heat sink into place.
6.Plug the CPU fan power cable into the CPU cooling fan power supply connector on the main board.
4.3 Memory installation
This main board supports DDR200/DDR266 DDR memory you may install 64/128/256/512MB 184 pin DDR memory. DDR SDROM uses additional power and ground lines and requires 184-pin 2.5V unbuffered DIMM module rather than the 168pin 3.3V unbuffered DIMM used by SDRAM.
Follow these instructions to install the Memory:
1.Push the latches on each side of the DIMM slot down.
2.Align the memory module with the slot. The DIMM slots are keyed with notches and the DIMMS are keyed with cutouts so that they can only be installed correctly.
3.Check that the cutouts on the DIMM module edge connector match the notches in the DIMM slot.
4.Install the DIMM module into the slot and press it firmly down until it seats correctly. The slot latches are levered upwards and latch on to the edges of the DIMM.
5.Install any remaining DIMM modules.
4.4 IDE Devices Installation
IDE devices include hard disk drives, high-density diskette drives, and CD-ROM or DVD-ROM drives, among others.
The main board ships with an IDE cable that can support one or two IDE devices. If you connect two devices to a single cable, you must configure one of the drives as Master and one of the drives as Slave. The documentation of the IDE device will tell you how to configure the device as a Master or Slave device. The Master device connects to the end of the cable.
4.5 Other Device Installation
4.5.1 Floppy Disk Drive Installation
This main board ships with a floppy disk drive cable that can support one or two drives. Drives can be 3.5” or 5.25” wide, with capacities of 360K, 720K, 1.2MB, 1.44MB, or 2.88MB.
Install your drives and connect power from the system power supply. Use the cable provided to connect the drives to the floppy disk drive connector floppy.
4.5.2 Sound Connector Port Installation
This main board has three audio ports connects audio device.
The left side jack (green) is for a stereo line-out signal. The middle jack (gray) is for a stereo line-in signal. The right side jack (red) is for a microphone.
4.5.3 Wake on LAN (WOL)
If you have installed a LAN card, use the cable provided with the card to plug into the main board WOL connector. This enables the Wake on LAN feature. When you system is in a power saving mode, any LAN signal automatically resumes the system. You must enable this item using the power Management page of the Setup Utility.
4.5.4 Clear CMOS (JP3)
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM data. The RAM data in CMOS, that include system setup information such as system passwords, is powered by the onboard button cell battery.
1.Turn OFF the computer and unplug the power cord.
2.Move the jumper cap from pin 1-2(default) to pin 2-3. Keep the cap on pin 2-3 for about 5-10 seconds, and then move the cap back to pinsl-2.
3.Plug the power cord and turn ON the computer.
4.Hold down the <DEL> key during the boot process and enter BIOS setup to re-enter data.
Note1: Except when clearing RTC RAM, never remove the cap on CLRTC1 jumper default position. Removing the cap will cause system boot failure!
Note2: You do not need to clear the RTC when the system hangs due to over clocking. For system failure due to over clocking, use the C.P.R. (CPU Parameter Recall) feature. Shut down and reboot the system so BIOS can automatically reset parameter settings to defaults values.
