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 Modules 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. Flash ROM Boot Block Programming (BBLKW) This sets the operation mode of the boot block area of the Programmable Flash ROM to allow programming in the Enabled position. This is required only if prompted by the Flash Memory Writer Utility as shown in BIOS SOFTWARE. BBLKW [1-2] (Default) [2-3] BBLKW R Disabled/Protect (Default) BBLKW Enabled III. INSTALLATION (Jumpers) Programming Disabled Enabled Boot Block Programming 2.
III. INSTALLATION 3. Keyboard Power Up (KBPWR) (Reserved for future use) Set this jumper to Enable if you wish to use your keyboard to power up your system. Requires an ATX power supply that can supply at least 300mAmp on the +5VSB lead and new BIOS support. The default is set to Disable because your system will not function withtout the proper ATX power supply. Setting Disable Enable KBPWR [1-2] (default) [2-3] R KBPWR 1 2 3 KBPWR 1 2 3 Disable (Default) Enable III.

III. INSTALLATION Compatible Cyrix CPU Identification The only Cyrix 6x86-PR166+ CPU that is supported on this motherboard 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. 6. Voltage Regulator Output Selection (VID0, 1, 2) These jumpers set the voltage supplied to the CPU. Switching regulators allow some jumper settings to be the same for two voltages of different power planes.
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 fit in only one orientation as shown because the plastic safety tab on one end of the SIMM sockets requires the notched end of the SIMM memory modules. 1 2 3 4 R III. INSTALLATION (System Memory) Notched End 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 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. SIMM modules have the same pin contact on both sides. DIMM modules are longer and have different pin contact on each side and therefore have a higher pin density. R 20 Pins DIMM Socket 2 III.
III. INSTALLATION 3. Central Processing Unit (CPU) The motherboard provides a 321-pin ZIF Socket 7 that is backwards 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. WARNING! Without a fan circulating air on the CPU, the CPU can overheat and cause damage to both the CPU and the motherboard. III.
III. INSTALLATION 4. Expansion Cards WARNING! Make sure that you 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 on any hardware and software settings that may be required to setup your specific card. Expansion Card Installation Procedure: 5. 6. 7. 8. 9. Read the documentation for your expansion card.
III. INSTALLATION The original ISA expansion card design, now referred to as “Legacy” ISA cards, requires that you configure the card’s jumpers manually and then install it in any available slot on the ISA bus. You may use Microsoft’s Diagnostic (MSD.EXE) utility included in the Windows directory to see a map of your used and free IRQs. For Windows 95 users, the “Control Panel” icon in “My Computer,” contains a “System” icon which gives you a “Device Manager” tab.
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 ASUS 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 some floppy drives.
III. INSTALLATION 3. Parallel Printer Connector (PRINTER, 26-1 pin block) This connector supports the included parallel port ribbon cable with mounting bracket. Connect the ribbon cable to this connection and mount the bracket to the case on an open slot. A PS/2 mouse connector is included for the USB/IR/ Mouse onboard connector if the optional USB/MIR connector is not used.
III. INSTALLATION 5. CPU Cooling Fan Connectors (FAN, 3 pins) This connector supports a 3-pin CPU cooling fan of 500mAMP (6WATT) or less with a minimum of 3,500RPM. Depending on the fan manufacturer, the wiring and plug may be different. The red wire should be Positive, the black should be Ground, and the yellow wire should be Rotation signal. WARNING! The CPU and/or motherboard will overheat if there is no airflow across the CPU.
III. INSTALLATION 7. Primary / Secondary IDE connectors (Two 40-1 pin block) 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). If you install two hard disks, you must set the second drive to Slave mode. Refer to the documentation of your hard disk for the jumper settings.
III. INSTALLATION 9. ATX Power Supply Connector (ATXPWR, 20-pin block) This connector connects to a ATX power supply. The plug from the power supply will only insert in one orientation because of the different hole sizes. Find the proper orientation and push down firmly making sure that the pins are aligned. IMPORTANT: Make sure that your ATX power supply can supply at least 10mAmp on the 5-volt standby lead (5VSB).
III. INSTALLATION 11. USB, Infrared, PS/2 Mouse Module Connector (USB_IR_MOUSE, 18-1 pin block) If you want to use USB, PS/2 mouse, or infrared (IrDA) devices, you need to purchase an external connector set. The external connector set connects to the 18-pin block and mounts to an open slot on your computer’s chassis. The system will direct IRQ12 to the PS/2 mouse if one is detected. If not detected, expansion cards can use IRQ12.
III. INSTALLATION III. INSTALLATION (Connectors) 13. Message LED Lead (MSG.LED, 2 pins) 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 messages waiting in the inbox. This function requires ACPI OS support. 14.
III. INSTALLATION 20. Wake on LAN Activity Connector (3-pin WAKE_LAN) The WAKE_LAN connector allows the system to power up when there is a wakeup package (signal) received from the network through the ASUS PCIL101 LAN card. Requires the ASUS PCI-L101 and an ATX power supply with at least 720mAmp 5VSB. R +5V Standby Ground PME III.
