2-1 Chapter 2 Hardware Installation This chapter gives you a step-by-step procedure on how to install your system. Follow each section accordingly. Caution: Electrostatic discharge (ESD) can damage your processor, disk drives, expansion boards, and other components. Always observe the following precautions before you install a system component. 1. Do not remove a component from its protective packaging until you are ready to install it. 2. Wear a wrist ground strap and attach it to a metal part of the system unit before handling a component. If a wrist strap is not available, maintain contact with the system unit throughout any procedure requiring ESD protection.

The only jumper left is to clear CMOS, which is a safety hook if you forget the password. 2.2.1 Selecting the CPU Frequency Pentium II VID signal and SMbus clock generator provide CPU voltage autodetection and allow user to set CPU frequency through CMOS setup, no jumper or switch is needed. The correct CPU information is saved into EEPROM, with these technologies, the disadvantages of Pentium base jumper-less design are eliminated. There will be no worry of wrong CPU voltage detection and no need to re-open the housing if CMOS battery loss. The CPU frequency selection is set by going into: BOIS Setup à Chipset Features Setup à CPU Clock Frequency (The possible setting is 66, 68.5, 75 and 83.3 MHz) BOIS Setup à Chipset Features Setup à CPU Clock Ratio (The possible setting is 1.5x, 2x, 2.5x, 3x, 3.5x, 4x, 4.5x, 5x, 5.5x, 6x, 6.5x, 7x, 7.5x, and 8x) Core frequency = Ratio * External bus clock INTEL Pentium II CPU Core Frequency Ratio External Bus Clock Klamath 233 233MHz = 3.5x 66MHz Klamath 266 266MHz = 4x 66MHz Klamath 300 300MHz = 4.5x 66MHz Klamath 333 333MHz = 5x 66MHz Celeron 266 266MHz= 4x 66MHz Celeron 300 300MHz 4.5x 66MHz Hardware Installation 2-5 2.2.2 Setting the CPU Voltage This motherboard supports Pentium II VID function, the CPU core voltage is automatically detected, the range is from 1.3V to 3.5V. 2.2.3 Clearing the CMOS JP14 1-2 2-3 Clear CMOS Normal operation (default) Clear CMOS You need to clear the CMOS if you forget your system password. To clear the CMOS, follow the procedures listed below: JP14 1 2 3 Normal Operation (default) JP14 1 2 3 Clear CMOS The procedure to clear CMOS: 1. Turn off the system and unplug the AC power. 2. Remove ATX power cable from connector PWR2. 3. Locate JP14 and short pins 2-3 for a few seconds. 4. Return JP14 to its normal setting by shorting pins 1-2. 5. Connect ATX power cable back to connector PWR2. 6. Turn on the system power. 7. Press during bootup to enter the BIOS Setup Utility and specify a new password, if needed. Tip: If your system hangs or fails to boot because of over-clocking, please clear CMOS and the system will go back to default setting (233MHz). Tip: Except using JP14, you may also press key. By this smart design, it would be more convenient to clear CPU frequency setting. For using this function, you just need to press key first and then press Power button at the same time. Please note that do not release key until POST screen appearing .

IDE1 is also known as primary channel and IDE2 as secondary channel, each channel supports two IDE devices that makes total of four devices. In order to work together, the two devices on each channel must be set differently to master and slave mode, either one can be hard disk or CDROM. The setting as master or slave mode depends on the jumper on your IDE device, please refer to your hard disk and CDROM manual accordingly. Connect your first IDE hard disk to master mode of the primary channel. If you have second IDE device to install in your system, connect it as slave mode on the same channel, and the third and fourth device can be connected on secondary channel as master and slave mode respectively. 1 40 2 39 IDE2 1 40 2 39 IDE1 Hardware Installation 2-12 Caution: The specification of IDE cable is maximum 46cm (18 inches), make sure your cable does not excess this length.

Please see the pin definitions to connect the cable. Pin 1 2 3 4 Description 1234 Mono In/Mic Out Hardware Installation 2-17 2.4 Configuring the System Memory Pin 1 The DIMM types supported are EDO (Extended Data Out) and SDRAM (Synchronous DRAM). This mainboard has three 168 pin DIMM sockets (Dual-in-line Memory Module) that allow you to install system memory up to 256MB. DIMM modules can be identified by the following factors: I. Size: single side, 1Mx64 (8MB), 2Mx64 (16MB), 4Mx64 (32MB), 8Mx64 (64MB), 16Mx64 (128MB), and double side, 1Mx64x2 (16MB), 2Mx64x2 (32MB), 4Mx64x2 (64MB), 8Mx64x2 (128MB). Tip: Here is a trick to check if your DIMM is single-side or double-side -- if there are traces connected to golden finger pin 114 and pin 129 of the DIMM, the DIMM is probably double-side; otherwise, it is single-side. Following figure is for your reference. 168 85 Pin 129 Pin 114 Warning: If you want to install DRAMs on DIMM2 and DIMM3 at the same time, it is very important to identify single/double side. Under this configuration, only single side DRAMs are acceptable. II. Speed: SDRAM: normally marked as as -12, which means the clock cycle time is 12ns and maximum clock of this SDRAM is 83MHz. Sometimes you can also find the SDRAM marked as -67, which means maximum clock is 67MHz. EDO: the access time of EDO RAM can be 60ns or 70ns. Hardware Installation 2-18 III. Buffered and non-buffered: This motherboard supports non-buffered DIMMs. You can identify non-buffered DIMMs and buffered DIMMs according to the position of the notch, following figure is for your reference: buffered non-buffered Reserved Because the positions are different, only non-buffered DIMMs can be inserted into the DIMM sockets on this motherboard. Although most of DIMMs on current market are non-buffered, we still recommend you to ask your dealer for the correct type. IV. 2-clock and 4-clock signals: Although both of 2-clock and 4-clock signals are supported by AX6LC Lite, we strongly recommend you to choose 4- clock SDRAM in consideration of reliability. Tip: To identify 2-clock and 4-clock SDRAM, you may check if there are traces connected to golden finger pin 79 and pin 163 of the SDRAM. If there are traces, the SDRAM is probably 4-clock; Otherwise, it is 2-clock. V. Parity: This motherboard supports standard 64 bit wide (without parity) and 72-bit wide (with parity) DIMM modules. There is no jumper setting required for the memory size or type. It is automatically detected by the system BIOS, and the total memory size is to add them together. The maximum is 256MB. EX chipset only supports 3V EDO or SDRAM, so we can mix EDO and SDRAM without any problem. Every DIMM socket can be EDO or SDRAM. Please note that the maximum DRAM size of DIMM1 is 128MB, but DIMM2 plus DIMM3 can only be 128MB. Total Memory Size = Size of DIMM1 + Size of DIMM2 + Size of DIMM3 Hardware Installation 2-19 Following table list the recommended DRAM combinations of DIMM: DIMM Data chip Bit size per side Single/ Double side Chip count DIMM size Recommended 1M by 16 1Mx64 x1 4 8MB Yes 1M by 16 1Mx64 x2 8 16MB Yes 2M by 8 2Mx64 x1 8 16MB Yes 2M by 8 2Mx64 x2 16 32MB Yes 4M by 16 4Mx64 x1 4 32MB Yes 4M by 16 4Mx64 x2 8 64MB Yes 8M by 8 8Mx64 x1 8 64MB Yes 8M by 8 8Mx64 x2 16 128MB Yes DIMM Data chip Bit size per side Single/ Double side Chip count DIMM size Recommended 2M by 32 2Mx64 x1 2 16MB Yes, but not tested. 2M by 32 2Mx64 x2 4 32MB Yes, but not tested.

To use parity check you need 72 bit DIMM (64+8 bit parity), which are automatically detected by BIOS. Hardware Installation 2-21 Warning: The driving capability of new generation chipset is limited because the lack of memory buffer (to improve performance). This makes DRAM chip count an important factor to be taking into consideration when you install DIMM. Unfortunately, there is no way that BIOS can identified the correct chip count, you need to calculate the chip count by yourself. The simple rule is: By visual inspection, use only DIMM which is less than 16 chips. Tip: The parity mode uses 1 parity bit for each byte, normally it is even parity mode, that is, each time the memory data is updated, parity bit will be adjusted to have even count "1" for each byte. When next time, if memory is read with odd number of "1", the parity error is occurred and this is called single bit error detection.
