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 DRAM and SRAM 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. Total Level 2 Cache Size Setting (JP14) This jumper sets the total amount of L2 cache that is present. If you have both onboard cache chips (see "Map of Motherboard" for locations) and a Cache Expansion Slot, then you have 256KB. If you only have onboard cache chips, then you have 512KB. An "ASUS" or "COAST" cache module can be used to upgrade the 256KB version to 512KB. If there is no onboard cache, you may install a cache module of either 256KB or 512KB.
III. INSTALLATION 3. Memory Cacheable Size (JP15) The default of 64MB uses only the onboard TAG SRAM which allows cacheable memory up to 64MB. If you install DRAM above 64MB and wish to allow cacheable memory above 64MB, you need to install a TAG SRAM upgrade or use a cache module with an extended TAG SRAM (such as 256KB ASUS CM1 Rev 3.0 with 2 TAG SRAM's) but not both and set this jumper to 512MB. See page 12 for TAG SRAM upgrade and page 14 for cache module information.
III. INSTALLATION 5. CMOS RAM (JP17) This clears the user-entered information stored in the CMOS RAM of the Real Time Clock such as hard disk information and passwords. To clear the CMOS data: (1) Turn off the PC, (2) Set jumper to "Clear," (3) Power on the PC, (4) Turn off the PC, (5) Set jumper to "Operation," (6) Power on the PC, (7) Hold down during bootup and enter BIOS setup to re-enter user information.
III. INSTALLATION 7. CPU External Clock (BUS) Frequency Selection (JP9, JP10) These jumpers tells the clock generator what frequency to send to the CPU to 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). 8. CPU to BUS Frequency Ratio (JP12, JP13) These jumpers set the frequency ratio between the Internal frequency of the CPU and the External frequency (called the BUS Clock) within the CPU.
III. INSTALLATION 9-10. Single/Dual Power Plane CPU Voltage Regulator Selections The following jumpers set the voltage supplied to the CPU. Determine whether your CPU has a Single Power Plane or Dual Power Planes and then the voltage that it uses. When a single power plane CPU is installed, the dual power plane selections will be automatically disabled. When a dual power plane CPU is installed, the single power plane selections will be automatically disabled.
III. INSTALLATION 2. System Memory (DRAM & SRAM) This motherboard supports four 72-pin SIMMs of 4MB, 8MB, 16MB, 32MB, or 64MB to form a memory size between 8MB to 256MB. The DRAM can be either 60ns or 70ns Fast Page Mode (Asymmetric or Symmetric) or EDO. To support ECC, you must use true (opposed to phantom parity generated by logic chips) 36-bit parity-type DRAM (e.g. 8 chips + 4 parity chips) in pairs for all modules. Mixing 32-bit non-parity DRAM (e.g. 8 chips) and 36-bit DRAM (e.g.
III. INSTALLATION DRAM Memory Installation Procedures: 1. The SIMM memory modules will only fit in one orientation as shown because of a "Plastic Safety Tab" on one end of the SIMM sockets which requires the "Notched End" of the SIMM memory modules. 1 2 3 4 Notched End Bank 1 III. INSTALLATION (DRAM Memory) Bank 0 72 Pin SIMM DRAM Sockets & Module 2. Press the memory module firmly into place starting from a 45 degree angle making sure that all the contacts are aligned with the sockets. 3.
III. INSTALLATION Static RAM (SRAM) for Level 2 (External) Cache The motherboard you purchase may have either 0KB, 256KB, or 512KB onboard. If you have both onboard cache chips (see "Map of Motherboard" for locations) and a Cache Expansion Slot, then you have 256KB. If you only have onboard cache chips, then you have 512KB. An "ASUS" or "COAST" cache module can be used to upgrade the 256KB version to 512KB. If there is no onboard cache, you may install a cache module of either 256KB or 512KB.
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. Apply thermal jelly to the CPU top and then install the fan onto the CPU. WARNING: Without a fan, the CPU can overheat and cause damage to both the CPU and the motherboard.
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. ATX power supplies may power on if certain motherboard components or connections are touched by metallic objects. First read your expansion card documentation on any hardware and software settings that may be required to setup your specific card.
III. INSTALLATION cards. 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 ASUS MediaBus Card ASUS MediaBus allows a cost-efficient solution to a complete multimedia system. The advantages of using one add-on card is to reduce the slot requirements and compatibility problems in order to maximize the Plug and Play advantages. The add-on card inserts into the shared PCI 4 / MediaBus 2.0 Slot. NOTE: This motherboard uses MediaBus Rev. 2.0. The previous MediaBus cards designed for MediaBus Rev. 1.2 will not fit into the MediaBus Rev 2.0 that is on this motherboard.
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" on page 4. 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 5. ATX Power Supply Connector (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. 12.0V 5VSB PW-0K GND 5.0V GND 5.0V GND 3.3V 3.3V 5.0V 5.0V -5.0V GND GND GND PS-ON GND -12.0V 3.
III. INSTALLATION 6. Primary / Secondary IDE connectors (Two 40-pin Block) This connector supports 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 configure the second drive to Slave mode by setting its jumpers accordingly. Please refer to the documentation of your hard disk for the jumper settings.
III. INSTALLATION 8. IDE Activity LED (IDE_LED) This connector connects to the hard disk activity indicator light on the case. + IDE_LED IDE Activity LED 9. System Power LED (CON1) This 2-pin connector lights the system power LED when the motherboard has power. Works the same as the next System Power LED. See the figure on the next page. III. INSTALLATION (Connectors) 10.
III. INSTALLATION 12. ATX Power Switch (CON1) (ATX Power Supply Only) The system power is controlled by a momentary switch connected to this lead. Pushing the button once will turn on the system and pushing another time will turn off the system. The system power LED shows the status of the system's power. This connection does not have a function when a standard power supply is used. See the figure below. 13.
III. INSTALLATION 15. CPU Cooling Fan Connector (FAN) This connector supports a CPU cooling fan of 500mAMP (6WATT) or less. Orientate the fan so that the heat sink fins allow airflow to go across the onboard heat sink(s) instead of the expansion slots. Depending on the fan manufacturer, the wiring and plug may be different. The red wire should be positive, while the black should be ground. Connect the fan's plug to the board taking into consideration the polarity of the this connector.
III. INSTALLATION Power Connection Procedures III. INSTALLATION (Power Connections) 1. After all jumpers and connections are made, close the system case cover. 2. Make sure that all switches are in the off position as marked by . 3. Connect the power supply cord into the power supply located on the back of your system case as instructed by your system user's manual. 4. Connect the power cord into an power outlet that is equipped by a surge protector. 5.
