Hardware Installation 2.2 Jumpers Jumpers are made by pin headers and plastic connecting caps for the purpose of customizing your hardware. Doing so requires basic knowledge of computer hardware, be sure you understand the meaning of the jumpers before you change any setting. The onboard jumpers are normally set to their default with optimized settings. On the mainboard, normally there is a bold line marked beside pin 1 of the jumper, sometimes, there are numbers also.

Caution: For better signal quality, it is recommended to set far end side device to master mode and follow the suggested sequence to install your new device . Please refer to following figure.
Hardware Installation 2.3.9 Hard Disk LED The HDD LED connector is marked as HDD LED on the board. This connector is designed for different type of housing, actually only two pins are necessary for the LED. If your housing has four pin connector, simply plug it in. If you have only two pin connector, please connect to pin 1-2 or pin 3-4 according to the polarity.
Hardware Installation 1 Keylock Power LED 11 + + Green LED + + Suspend SW + + Speaker Reset 10 20 PANEL Other housings may have a 12-pin connector. If your housing has this type of connector, connect it to PANEL as shown in the figure. Make sure that the red wire of the connector is connected to +5V. 1 11 +5V 10 20 PANEL Note: If your housing comes with Turbo switch and Turbo LED connectors, you may use these connectors for Suspend switch and Green mode LED functions, respectively.
Hardware Installation 2.3.11 Keyboard The onboard keyboard connector is a five-pin AT-compatible connector marked as KB1. The view angle of drawing shown here is from back panel of the housing. Note: The mini DIN PS/2 keyboard connector is optional.
Hardware Installation 2.3.12 IrDA Connector Serial port 2 can be configured to support wireless infrared module, with this module and application software such as Laplink, user can transfer files to or from laptops, notebooks, PDA and printers. This mainboard supports IrDA (115Kbps, 1 meter) as well as ASK-IR (19.2Kbps). Install infrared module onto IrDA connector and enable infrared function from BIOS setup, make sure to have correct orientation when you plug onto IrDA connector.
Hardware Installation 2.4 Configuring the System Memory Pin 1 of DIMM2 Pin 1 of DIMM1 This mainboard has four 72 pin SIMM sockets (Single-in-line Memory Module) and two 168 pin DIMM socket (Dual-in-line Memory Module) that allow you to install system memory from minimum 8MB up to maximum 256MB.
Hardware Installation II. Speed: 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. III. Buffered and non-buffered: This motherboard supports non-buffered DIMMs.
Hardware Installation Tip: EDO DRAM is designed to improve the DRAM read performance. Unlike traditional fast page mode, that tristates the memory output data to start the precharge activity, EDO DRAM holds the memory data valid until the next memory access cycle, which is similar to pipeline effect and reduces one clock state. There is no jumper setting required for the memory size or type. It is automatically detected by the system BIOS.
Hardware Installation For double side memory module, there is one limitation. This mainboard supports only 4 RAS# (Row address latch) signals for DRAM control. They can only be occupied by one DRAM module, they can not be shared. The simple rule is: If double side module at either Bank0 or DIMM1, the other must be empty. If you use at DIMM1, Bank0 must be empty. Bank1 and DIMM2 have the same limitation. Double side module at either Bank0 or DIMM1, the other must be empty.
Hardware Installation Tip: If you have DIMM made by 3V EDO, it is possible that TX chipset can support it. But because it is so rare, the only 3V EDO DIMM had been tested by this mainboard is Micron MT4LC2M8E7DJ-6. Warning: Do not use SIMM and SDRAM DIMM together unless you have 5V tolerance SDRAM (such as Samsung or TI). The FPM/EDO operate at 5V while SDRAM operates at 3.3V. If you combine them together the system will temporary work fine; however after a few months, the SDRAM 3.
Hardware Installation Warning: Do not install any SIMM that contains more than 24 chips. SIMMs contain more than 24 chips exceed the chipset driving specification. Doing so may result in unstable system behavior. Warning: Although Intel TX chipset supports x4 SDRAM chip. Due to loading issue, it is not recommended to use this kind of SDRAM. Tip: The SIMM/DIMM chip count can be calculated by following example: 1. For 32 bit non-parity SIMM using 1M by 4 bit DRAM chip, 32/4=8 chips. 2.
Hardware Installation SIMM Data chip SIMM Parity chip Bit size per side Chip count SIMM size Recommended 16Mx32 Single/ Double side x1 16M by 4 None 8 64MB Yes, but not tested. 16M by 4 None 16Mx32 x2 16 128MB Yes, but not tested. 16M by 4 16M by 4 16Mx36 x1 9 64MB Yes, but not tested. 16M by 4 16M by 4 16Mx36 x2 18 128MB Yes, but not tested.
Hardware Installation using 1M by 4 bit chip is 1Mx32 bit, that is, 1M x 4 byte= 4MB. For double side SIMM, simply multiply it by 2, that is, 8MB.
Hardware Installation 2.5 CPU Thermal Protection This motherboard implements special thermal protection circuit below the CPU. When temperature is higher than a predefined value, the CPU speed will automatically slow down and there will be warning from BIOS and also ADM (AOpen Desktop Manager, similar as Intel LDCM) or HWMON utility software. ADM is a very powerful network and hardware monitor software.
