III. INSTALLATION Installation Steps Before using your computer, you must complete the following steps: 1. 2. 3. 4. 5. 6. Set Jumpers on the Motherboard Install System Memory Install the Central Processing Unit (CPU) Install Expansion Cards Connect Ribbon Cables, Cabinet Wires, and Power Supply Setup the BIOS Software 1. Jumpers III. INSTALLATION (Jumpers) Several hardware settings are made through the use of jumper caps to connect jumper pins (JP) on the motherboard.
III. INSTALLATION Jumper Settings 1. Onboard Multi-I/O Selection (M/IO) You can selectively disable each onboard Multi-I/O item (floppy, serial, parallel, and IrDA) through the Chipset Features Setup of BIOS SOFTWARE or disable all multi-I/O items at once with the following jumper so you can use your own multi-I/O card. M/IO [1-2] (Default) [2-3] R M/IO 1 2 3 M/IO 1 2 3 Enable (Default) Disabled III. INSTALLATION (Jumpers) Multi-I/O Enable Disable Multi I/O Setting (Enable / Disable) 2.
III. INSTALLATION Compatible Cyrix CPU Identification The only Cyrix CPU that is supported on this motherboard is labeled Cyrix 6x86 PR166+ but must be Revision 2.7 or later. Look on the underside of the CPU for the serial number. The number should read G8DC6620A or later. 3. Voltage Regulator Output Selection (VID0, 1, 2, 3) These jumpers set the voltage supplied to the CPU. The voltage regulators will automatically detect and switch between Single Power Plane & Dual Power Planes. III.
III. INSTALLATION 4. CPU External (BUS) Frequency Selection (FS0, FS1, FS2) These jumpers tell the clock generator what frequency to send to the CPU. These allow the selection of the CPU’s External frequency (or BUS Clock). The BUS Clock times the BUS Ratio equals the CPU’s Internal frequency (the advertised CPU speed). 5.

III. INSTALLATION 2. System Memory (SIMM & DIMM) This motherboard supports four 72-pin, 32-bit SIMMs (Single Inline Memory Modules) of 4, 8, 16, 32, or 64MB to form a memory size between 8MB to 256MB. The SIMMs can be either 60ns or 70ns Fast Page Mode (FPM) (Asymmetric or Symmetric), or Enhanced Data Out (EDO) (BEDO & Parity are not supported). SIMMs must be installed in pairs so that each Row (see motherboard layout for Row locations) contains 64-bits of the same size and type of memory chips.
III. INSTALLATION SIMM Memory Installation 1. The SIMM memory modules will only fit in one orientation as shown because of a safety tab on one end of the SIMM sockets, which requires the notched end of the SIMM memory modules. R 4 3 2 1 III. INSTALLATION (System Memory) 72 Pin SIMM Sockets 2. Press the memory module firmly into place starting from a 45 degree angle making sure that all the contacts are aligned with the socket. 3.
III. INSTALLATION DIMM Memory Installation Procedures: Insert the module(s) as shown. Because the number of pins are different on either side of the breaks, the module will only fit in the orientation as shown. DRAM SIMM modules have the same pin contact on both sides. SDRAM DIMM modules have different pint contact on each side and therefore have a higher pin density. 88 Pins 60 Pins 20 Pins R III.
III. INSTALLATION 3. Central Processing Unit (CPU) The motherboard provides a 321-pin ZIF Socket 7 that is backward compatible with ZIF Socket 5 processors. The CPU that came with the motherboard should have a fan attached to it to prevent overheating. If this is not the case then purchase a fan before you turn on your system. Apply thermal jelly to the CPU top and then install the fan onto the CPU.
III. INSTALLATION 4. Expansion Cards WARNING! Unplug your power supply when adding or removing expansion cards or other system components. Failure to do so may cause severe damage to both your motherboard and expansion cards. First read your expansion card documentation for hardware and software settings that may be required to set up your specific card. Expansion Card Installation Procedure 5. 6. 7. 8. 9. Read the documentation for your expansion card. Set any necessary jumpers on your expansion card.
III. INSTALLATION To simplify this process, the motherboard complies with the Plug and Play (PnP) specification, which was developed to allow automatic system configuration whenever a PnP-compliant card is added to the system. For PnP cards, IRQs are assigned automatically from those available. If the system has both legacy and PnP ISA cards installed, IRQs are assigned to PnP cards from those not used by legacy cards.
III. INSTALLATION 5. External Connectors WARNING! Some pins are used for connectors or power sources. These are clearly separated from jumpers in “Map of the Motherboard.” Placing jumper caps over these will cause damage to your motherboard. IMPORTANT: Ribbon cables should always be connected with the red stripe on the Pin 1 side of the connector. The four corners of the connectors are labeled on the motherboard. Pin 1 is the side closest to the power connector on hard drives and floppy drives.
III. INSTALLATION 3. Parallel Printer Connector (25-pin Female) You can enable the parallel port and choose the IRQ through “Onboard Parallel Port” in Chipset Features Setup of the BIOS SOFTWARE. NOTE: Serial printers must be connected to the serial port. Parallel (Printer) Port (25-pin Female) III. INSTALLATION (Connectors) 4. Serial Port COM1 and COM2 Connectors (Two 9-pin Male) The two serial ports can be used for pointing devices or other serial devices.
III. INSTALLATION 6. Universal Serial BUS Ports 1 & 2 (Two 4-pin Female) Two USB ports are available for connecting USB devices. USB 1 Univeral Serial Bus (USB) 2 III. INSTALLATION (Connectors) 7. Primary / Secondary IDE connectors (Two 40-1pin IDE) These connectors support the provided IDE hard disk ribbon cable. After connecting the single end to the board, connect the two plugs at the other end to your hard disk(s).
III. INSTALLATION 8. IDE activity LED (2-pin IDE_LED) This connector supplies power to the cabinet’s IDE activity LED. Read and write activity by devices connected to the Primary or Secondary IDE connectors will cause the LED to light up. TIP: If the case-mounted LED does not light, try reversing the 2-pin plug. R + IDE_LED IDE Activity LED III. INSTALLATION (Connectors) 9. Chassis , CPU , & Power Supply Fan Connectors (3-pin FANPWR) These connectors support cooling fans of 500mAMP (6WATT) or less.
III. INSTALLATION 10. IrDA / Fast IR-Compliant infrared module connector (5-pin IR) This connector supports the optional wireless transmitting and receiving infrared module. This module mounts to a small opening on system cases that support this feature. You must also configure the setting through “UART2 Use Infrared” in Chipset Features Setup to select whether UART2 is directed for use with COM2 or IrDA.
III. INSTALLATION 12. Message LED Lead (MSG LED) This indicates whether a message has been received from a fax/modem. The LED will remain lit when there is no signal and blink when there is data transfer or waiting in the inbox. This function requires OS and driver support. III. INSTALLATION (Connectors) 13.
