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). 4.
III. INSTALLATION Set the jumpers by the Internal speed of the Intel, AMD, IBM, or Cyrix CPU as follows: Freq. 166MHz 150MHz 133MHz 120MHz 100MHz 90MHz 75MHz Ratio A-2.5x A-2.5x A-2.0x A-2.0x A-1.5x A-1.5x A-1.5x BUS F. 66MHz 60MHz 66MHz 60MHz 66MHz 60MHz 50MHz (BUS Freq.
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. 5. 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.

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.

IV. BIOS SOFTWARE BIOS Features Setup BIOS Features Setup consists of configuration entries that allow you to improve your system performance, or let you set up some system features according to your preference. Some entries are required by the motherboard’s design to remain in their default settings. IV. BIOS (BIOS Features) A section at the lower right of the screen displays the control keys you can use. Take note of these keys and their respective uses.
IV. BIOS SOFTWARE IV. BIOS (BIOS Features) HDD Sequence SCSI/IDE First (IDE) When using both SCSI and IDE hard disk drives, IDE is always the boot disk using drive letter C (default setting of IDE). This new feature allows a SCSI hard disk drive to be the boot disk when set to SCSI. This allows multiple operating systems to be used on both IDE and SCSI drives or the primary operating system to boot using a SCSI hard disk drive.
IV. BIOS SOFTWARE C8000 - CBFFF Shadow to DC000 - DFFFF Shadow (Disabled) These fields are used for shadowing other expansion card ROMs. If you install other expansion cards with ROMs on them, you will need to know which addresses the ROMs use to shadow them specifically. Shadowing a ROM reduces the memory available between 640KB and 1024KB by the amount used for this purpose. ....................................................................................................................................
IV. BIOS SOFTWARE SDRAM CAS# Latency (3T) If you use ASUS SDRAM DIMM modules, you can set this to 2T for better performance, otherwise leave on default or check with your vendor for DIMM specs. SDRAM Speculative Read (Disabled) If Enabled, the CPU will issue predict commands to access the DRAM, if a miss occurs, the CPU will cancel this command. Some operating systems under certain situations have a problem utilizing this feature so it is normally Disabled.

VI. ASUS PCI SCSI Cards VI. ASUS SCSI Cards (SCSI BIOS) Symbios SCSI BIOS and Drivers Aside from the system BIOS, the Flash memory chip on the motherboard also contains the Symbios SCSI BIOS. This Symbios SCSI BIOS works in conjunction with the optional ASUS PCI-SC200 controller card to provide Fast SCSI-2 interface when using compatible SCSI devices or the ASUS PCI-SC860 SCSI controller cards to provide Ultra-Fast SCSI-2 interface when using Ultra-Fast SCSI-2 devices.
VI. ASUS PCI SCSI Cards VI. ASUS SCSI Cards (Setup) Setting Up the ASUS PCI-SC200 & PCI-SC860 There are two jumper settings you may need to make on the ASUS PCI-SC200 to set it up. One setting assigns the PCI INT interrupt, the other sets the card’s termination. The ASUS PCI-SC860 has no jumper settings but you should read the “Terminator Requirements.” Setting the INT Assignment for the ASUS PCI-SC200 You must use PCI INT A setting in order to properly assign the ASUS PCI-SC200’s interrupt.
VI. ASUS PCI SCSI Cards VI. ASUS SCSI Cards (Jumpers) Terminator Settings for the ASUS PCI-SC860 Many SCSI devices including the ASUS PCI-SC860 use a set of onboard active resistors to terminate the devices at the ends automatically. Automatic termination requires that the SCSI devices be connected in a straight linear connection or “chain.” Connect SCSI devices to one or two of the SCSI connectors in a linear “chain” for auto termination of the ASUS PCI-SC860 to be effective.
