III. INSTALLATION 5. CPU External (BUS) Frequency Selection (JP2, JP3) These jumpers tells 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). 6. CPU to BUS Frequency Ratio (JP4, 5, 6, 7) 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 III.
2. System Memory (DRAM/SDRAM & SRAM) This motherboard supports four 72-pin SIMMs (Single Inline Memory Modules) of 4MB, 8MB, 16MB, 32MB, 64MB to form a memory size between 8MB to 256MB. The DRAM can be either 60ns or 70ns Fast Page Mode (Asymmetric or Symmetric), Extended Data Output (EDO), or Burst Extended Data Output (BEDO). SIMMs must be installed in pairs so that each bank contains two of the same size memory modules.
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 Bank 0 Notched End Bank 1 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 socket. 3.

III. INSTALLATION 3. Central Processing Unit (CPU) The motherboard provides a 387-pin ZIF Socket 8. 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. (See page 24 "CPU Cooling Fan Connector"). III.
III. INSTALLATION 4. Expansion Cards First read your expansion card documentation on any hardware and software settings that may be required to setup your specific card. NOTE: PCI Slot 5 has a MediaBus extension 2.0 (see page 18) which allows the installation of a PCI card or a MediaBus card (optional multifunctional card) but not both. WARNING: Make sure that you unplug your power supply when adding or removing expansion cards or other system components.
III. INSTALLATION Both ISA and PCI expansion cards may need to use IRQs. System IRQs are available to cards installed in the ISA expansion bus first, and any remaining IRQs are then used by PCI cards. Currently, there are two types of ISA 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.
III. INSTALLATION ASUS MediaBus Card 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 5 / 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.
III. INSTALLATION 5. External Connectors 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. IDE ribbon cable must be less than 18in. (46cm), with the second drive connector no more than 6in. (15cm) from the first connector. 1.
3. Parallel Printer Connector (26 Pin Block) Connection for 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. It will then be available for a parallel printer cable. Note: Serial printers must be connected to the serial port. You can enable the parallel port and choose the IRQ through BIOS Setup on page 37 "Onboard Parallel Port.
III. INSTALLATION 5. Floppy drive connector (34-pin block ) This connector supports the provided floppy drive ribbon cable. After connecting the single end to the board, connect the two plugs on the other end to the floppy drives. (Pin 5 is removed to prevent inserting in the wrong orientation when using ribbon cables with pin 5 plugged). Pin 1 III. INSTALLATION (Connectors) Floppy Drive Connector 6. Power connector (12-pin block) This connector connects to a standard 5 Volt power supply.
III. INSTALLATION 7. 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 10. Reset switch lead (CON1) This 2-pin connector connects to the case-mounted reset switch for rebooting your computer without having to turn off your power switch This is a preferred method of rebooting in order to prolong the life of the system's power supply. See the figure below. 11. Keyboard lock switch lead (CON1) This 5-pin connector connects to the case-mounted key switch for locking the keyboard for security purposes. See the figure below. 12.
III. INSTALLATION 14. 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.
Power Connection Procedures 1. After all jumpers and connections are made, close the system case cover. 2.

VI. ASUS PCI-SC200 SCSI Card VI. ASUS PCI-SC200 (NCR SCSI BIOS) NCR SCSI BIOS and Drivers Aside from the system BIOS, the Flash memory chip on the motherboard also contains the NCR SCSI BIOS. This SCSI BIOS works in conjunction with the optional ASUS PCI-SC200 SCSI controller card to provide a complete PCI Fast SCSI-2 interface. All SCSI devices you install to your system require driver software to function. The NCR SCSI BIOS directly supports SCSI hard disks under the DOS, Windows and OS/2 environments.
VI. ASUS PCI-SC200 SCSI Card VI. ASUS PCI-SC200 (Setup) The ASUS PCI-SC200 SCSI Interface Card Your motherboard may have come with an optional SCSI (Small Computer System Interface) controller card, the PCI-SC200. The card is also available separately. This card works with the SCSI BIOS on the motherboard. Together, they provide a complete PCI Fast SCSI-2 interface. With the card installed in your system you can connect SCSI devices installed in your system case to the internal connector on the card.
VI. ASUS PCI-SC200 SCSI Card VI. ASUS PCI-SC200 (Jumpers) Setting the INT Assignment You must use PCI INT A setting in order to properly assign the card's interrupt. On the ASUS PCI-SC200, you assign the INT by setting jumper JP1 or JP2. The default setting for the card already is INT A, so you do not need to change the setting to use the ASUS PCI-SC200 with this motherboard.
VI. ASUS PCI-SC200 SCSI Card VI. ASUS PCI-SC200 (SCSI ID Numbers) Decide whether or not you need to terminate the ASUS PCI-SC200 based on its position in the SCSI chain. Only the devices at each end of the chain need to be terminated. If you have only internal or only external devices connected to the ASUS PCI-SC200, then you must terminate the ASUS PCI-SC200. If you have both internal and external devices connected, you must not terminate the card. See the following example which illustrates this concept.
