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.

IV. BIOS SOFTWARE Support Software FILELIST.TXT - View this file to see the files included in the support software. PFLASH.EXE - This is the Flash Memory Writer utility that updates the BIOS by uploading a new BIOS file to the programmable flash ROM chip on the motherboard. To determine the BIOS version, check the last four numbers of the code displayed on the upper left-hand corner of your screen during bootup. Larger numbers represent a newer BIOS file.
IV. BIOS SOFTWARE Main Menu 1. Save Current BIOS To File This option allows you to copy the contents of the flash memory onto a floppy disk. This gives you a backup copy of the original motherboard BIOS in case you need to reinstall it. Create a bootable DOS diskette without AUTOEXEC.BAT and CONFIG.SYS and save both PFLASH.EXE and the BIOS file(s) to it. Note: BIOS FEATURES SETUP Boot Sequence needs to be set to A first in order to boot from your disk drive A. 2.
IV. BIOS SOFTWARE Managing and Updating Your Motherboard’s BIOS Upon First Use of the Computer System 1. Create a bootable system floppy diskette by typing [FORMAT A:/S] from the DOS prompt without creating “AUTOEXEC.BAT” and “CONFIG.SYS” files. 2. Copy PFLASH.EXE to your new diskette. 3. Run PFLASH.EXE from your new diskette and select option 1 “Save Current BIOS to File.” Enter the “Current BIOS Revision:” for the file name.
IV. BIOS SOFTWARE 6. BIOS Setup The motherboard supports two programmable Flash ROM chips: 5 Volt and 12 Volt. Either of these memory chips can be updated when BIOS upgrades are released. Use the Flash Memory Writer utility to download the new BIOS file into the ROM chip as described in detail in this section. All computer motherboards provide a Setup utility program for specifying the system configuration and settings.
IV. BIOS SOFTWARE Load Defaults The Load BIOS Defaults option loads the minimum settings for troubleshooting. Load Setup Defaults, on the other hand, is for loading optimized defaults for regular use. Choosing defaults at this level will modify all applicable settings. A section at the bottom of the preceding screen displays the control keys for this screen. Take note of these keys and their respective uses.
IV. BIOS SOFTWARE Time To set the time, highlight the “Time” field and then press either / or <+>/<–> to set the current time. Follow the hour, minute and second format. Valid values for hour, minute and second are: (Hour: (00 to 23), Minute: (00 to 59), Second: (00 to 59). If you do not want to modify the current time, press three times to go to Hard Disks. NOTE: You can bypass the date and time prompts by creating an AUTOEXEC.BAT file.
IV. BIOS SOFTWARE Auto detection of hard disks on bootup For each field: Primary Master, Primary Slave, Secondary Master, and Secondary Slave, you can select Auto under the TYPE and MODE fields. This will enable auto detection of your IDE hard disk during bootup. This will allow you to change your hard disks (with the power off) and then power on without having to reconfigure your hard disk type.
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 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. Boot Sequence (C,A) This field determines where the system looks first for an operating system.
IV. BIOS SOFTWARE Video ROM BIOS Shadow (Enabled) This field allows you to change the video BIOS location from ROM to RAM. Relocating to RAM enhances system performance, as information access is faster than the ROM. 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.
IV. BIOS SOFTWARE Chipset Features Setup This “Chipset Features Setup” option controls the configuration of the board’s chipset. Control keys for this screen are the same as in the BIOS Features Setup screen. NOTE: SETUP Defaults are noted in parenthesis next to each function heading. Details of Chipset Features Setup IV. BIOS (Chipset Features) Auto Configuration (60ns DRAM) The default setting of 60ns DRAM sets the optimal timings for items 2 through 9 for 60ns DRAM modules.
IV. BIOS SOFTWARE 8-bit I/O Recovery Time (1 BUSCLK) Timing for 8-bit ISA cards Video BIOS Cacheable (Enabled) Allows the Video BIOS to be cached to allow faster execution. Leave on default setting of Enabled for better performance, otherwise Disabled. Memory Hole at Address (None) This features reserves either 14MB-16MB or 15MB-16MB memory address space to ISA expansion cards that specifically require this setting.
IV. BIOS SOFTWARE UART2 Use Infrared (Disabled) When enabled, this field activates the onboard infrared feature and sets the second serial UART to support the infrared module connector on the motherboard. If your system already has a second serial port connected to the onboard COM2 connector, it will no longer work if you enable the infrared feature. By default, this field is set to Disabled, which leaves the second serial port UART to support the COM2 serial port connector.
IV. BIOS SOFTWARE Power Management Setup IV. BIOS (Chipset Features) This “Power Management Setup” option allows you to reduce power consumption. This feature turns off the video display and shuts down the hard disk after a period of inactivity. NOTE: SETUP Defaults are noted in parenthesis next to each function heading. Details of Power Management Setup IV. BIOS (Power Management) Power Management (User Define) This field acts as the master control for the power management modes.
IV. BIOS SOFTWARE Video Off Method (DPMS OFF) This field defines the video off features. These options are available: DPMS OFF, DPMS Reduce ON, Blank Screen, V/H SYNC+Blank, DPMS Standby, and DPMS Suspend. The DPMS (Display Power Management System) features allow the BIOS to control the video display card if it supports the DPMS feature. Blank Screen only blanks the screen (or monitors without power management or “green” features).
IV. BIOS SOFTWARE PWR Up On Modem Act (Enabled) This allows either settings of Enabled or Disabled for powering up the computer (turns the ATX power supply on) when the modem receives a call while the computer is off. NOTE: The computer cannot receive or transmit data until the computer and applications are fully running, thus connection cannot be made on the first try.
IV. BIOS SOFTWARE PNP and PCI Setup This “PNP and PCI Setup” option configures the PCI bus slots. All PCI bus slots on the system use INTA#, thus all installed PCI cards must be set to this value. NOTE: SETUP Defaults are noted in parenthesis next to each function heading. Details of PNP and PCI Setup IV. BIOS (PnP / PCI) PNP OS Installed (No) This field allows you to use a Plug-and-Play (PnP) operating system to configure the PCI bus slots instead of using the BIOS.
IV. BIOS SOFTWARE DMA x Used By ISA (No/ICU) These fields indicate whether or not the displayed DMA channel for each field is being used by a legacy (non-PnP) ISA card. Available options include: No/ICU and Yes. The first option, the default setting, indicates either that the displayed DMA channel is not used or an ICU is being used to determine if an ISA card is using that channel.
IV. BIOS SOFTWARE Load BIOS Defaults This “Load BIOS Defaults” option allows you to load the troubleshooting default values permanently stored in the BIOS ROM. These default settings are non-optimal and disable all high performance features. To load these default settings, highlight “Load BIOS Defaults” on the main screen and then press . The system displays a confirmation message on the screen. Press and then to confirm. Press and then to abort.
IV. BIOS SOFTWARE Supervisor Password and User Password IV. BIOS (Passwords) These two options set the system passwords. “Supervisor Password” sets a password that will be used to protect the system and the Setup utility; “User Password” sets a password that will be used exclusively on the system. By default, the system comes without any passwords. To specify a password, highlight the type you want and then press . A password prompt appears on the screen.
IV. BIOS SOFTWARE IDE HDD Auto Detection This “IDE HDD Auto Detection” option detects the parameters of an IDE hard disk drive, and automatically enters them into the Standard CMOS Setup screen. IV. BIOS (Hard Disk Detect) Up to four IDE drives can be detected, with parameters for each listed inside the box. To accept the optimal entries, press or else select from the numbers displayed under the OPTIONS field (2, 1, 3 in this case); to skip to the next drive, press .
IV. BIOS SOFTWARE IMPORTANT: If your hard disk was already formatted on an older previous system, incorrect parameters may be detected. You will need to enter the correct parameters manually or use low-level format if you do not need the data stored on the hard disk. If the parameters listed differ from the ones used when the disk was formatted, the disk will not be readable. If the auto-detected parameters do not match the ones that should be used for your disk, do not accept them.
V. SUPPORT SOFTWARE Desktop Management Interface (DMI) Introducing the ASUS DMI Configuration Utility This motherboard supports DMI within the BIOS level and provides a DMI Configuration Utility to maintain the Management Information Format Database (MIFD). DMI is able to auto-detect and record information pertinent to a computer’s system such as the CPU type, CPU speed, and internal/external frequencies, and memory size.
V. SUPPORT SOFTWARE Using the ASUS DMI Configuration Utility Edit DMI (or delete) Use the ←→ (left-right) cursors to move the top menu items and the ↑↓ (up-down) cursor to move between the left hand menu items. The bottom of the screen will show the available keys for each screen. Press enter at the menu item to enter the right hand screen for editing. “Edit component” appears on top. The reversed color field is the current cursor position and the blue text are available for editing.
V. SUPPORT SOFTWARE Save MIFD You can save the MIFD (normally only saved to flash ROM) to a file by entering the drive and path here. If you want to cancel save, you may press ESC and a message “Bad File Name” appears here to show it was not saved. Load MIFD You can load the disk file to memory by entering a drive and path and file name here. Load BIOS Defaults V. SOFTWARE (Using DMI Utility) You can load the BIOS defaults from a MIFD file and can clear all user modified and added data.
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.
