Two Serial Port Connectors Type Serial Port A: DB-9 male connector with RS-232C.
Chapter 2 HARDWARE INSTALLATION ® The mainboard operates with Cyrix GXM/GX-LV processor. The mainboard uses a CPU socket called Socket 7 for easy CPU installation. The CPU should always have a Heat Sink and a cooling fan attached to prevent overheating.
2.1-2 CPU Core Speed Derivation Procedure 1. The Jumper Switch JCKM1 (1-2, 3-4, and 5-6) is used to set the Core/Bus (Fraction) ratio of the CPU. The actual core speed of the CPU is the Host Clock Frequency multiplied by the Core/Bus ratio. For example: CPU Clock 33.3MHz Core/Bus ratio...

2.1-4 Fan Power Connector: JFAN1 This connector support system cooling fan with +12V. It supports three pin head connector. When connecting the wire to the connector, always take note that the red wire is the positive and should be connected to the +12V, the black wire is Ground and should be connected to GND.

A battery must be used to retain the mainboard configuration in CMOS RAM. If you use the on-board battery, you must short 1-2 pins of JBAT1 to keep the CMOS data. JBAT1 Function JBAT1 Keep Data Clear Data Note: You can clear CMOS by shorting 2-3 pin, while the system is off. Then, return to 1-2 pin position.
2.3-1 Memory Bank Configuration The mainboard supports a maximum of 64MB of memory : It provides one 168-pin DIMMs (Double In-Line Memory Module) sockets. It supports 8 MB to 64 Mbytes DIMM memory module. The memory module can only support SDRAM(Synchronous DRAM) MODE DRAM. There are two kinds of DIMM specification supported by this mainboard: PC100 and PC66.
2.3-2 Memory Installation Procedures: A. How to install a DIMM Module Single Sided DIMM Double Sided DIMM 1. The DIMM slot has a two Notch Key “VOLT and DRAM”, so the DIMM memory module can only fit in one direction. 2.
2.3-3 Memory Population Rules 1. Supports SDRAM DIMM. 2. Supports 3.3 volt DIMM. 3. The DRAM addressing and the size supported by the mainboard is shown below: Table 2.3-1 SDRAM Memory Addressing DRAM MB/DIMM Address Size DRAM DRAM Density & Addressing Tech.

2.4-1 Power Switch Connect to a 2-pin push button switch. This switch has the same feature with JRMS1. 2.4-2 Reset Switch Reset switch is used to reboot the system rather than turning the power ON/ OFF. Avoid rebooting while the HDD LED is lit. You can connect the Reset switch from the system case to this pin.
