ASUS TX97 Smart Series Motherboards

Performance• SDRAM Optimized Performance - ASUS TX97 smart series motherboards

support the new generation memory - Synchronous Dynamic Random AccessMemory (SDRAM) which increases the data transfer rate from 264MB/s maxusing EDO memory to 528MB/s max using SDRAM.

• Double the IDE Transfer Speed - ASUS TX97 smart series motherboards withIntel 430TX PCIset improves IDE transfer rate using Bus Master UltraDMA/33IDE which can handle data transfer up to 33MB/s. The best of all is that thisnew technology is compatible with existing ATA-2 IDE specs so there is noneed to upgrade current hard drives or cables.

• Concurrent PCI - Concurrent PCI allows multiple PCI transfers from PCI masterbusses to memory to CPU.

• ACPI Ready - ACPI (Advanced Configuration and Power Interface) is alsoimplemented on all ASUS 430TX series of motherboards. ACPI provide moreEnergy Saving Features for the future operating systems (OS) supporting OSDirect Power Management (OSPM) functionality. With these features imple-mented in the OS, PCs can be ready around the clock everyday, yet satisfy allthe energy saving standards. To fully utilize the benefits of ACPI, an ACPI-supported OS such as in the next release of Windows 95 must be used.

• PC ’97 Compliant - Both the BIOS and hardware levels of ASUS TX97 seriesof motherboards meet PC ’97 compliancy. The new PC 97 requirements forsystems and components are based on the following high-level goals: Supportfor Plug and Play compatibility and power management for configuring andmanaging all system components, and 32-bit device drivers and installation pro-cedures for both Windows 95 and Windows NT.

Intelligence: (with optional LM78/75 Hardware Monitor only)• Fan Status Monitoring and Alarm - To prevent system overheat and system

damage, the CPU fan and system fans are monitored for RPM and failure. Eachfan can be set for its normal RPM range and alarm thresholds.

• Temperature Monitoring and Alert - To prevent system overheat and systemdamage, there is a heat sensor under the CPU and on the motherboard itself tomonitor CPU and system temperature to make sure the system is operating at asafe heat level to avoid any failures triggered by extremely high temperature.


II. FEATURES

TX97 SeriesII. FEATURES

• Voltage Monitoring and Alert: System voltage levels are monitored to ensurestable current to critical motherboard components. Voltage specifications aremore critical for future processors, so monitoring is necessary to ensure propersystem configuration and management.

• System Resources Alert: Today’s operating systems such as Windows 95, Win-dows NT, and OS/2, require much more memory and hard drive space to presentenormous user interfaces and run large applications. The system resource moni-tor will warn the user before the system resources are used up to prevent pos-sible application crashes. Suggestions will give the user information on manag-ing their limited resources more efficiently.

• Virus Write Protection - Normally, viruses can destroy data on storage mediasuch as hard drivers, floppy diskettes, and MO. Some new-generation viruseswill not only destroy data on storage media, but also clear BIOS data which isusually unprotected. ASUS TX97 series of motherboards were designed to co-operate with BIOS, chipset, and flash EPROM to disable write permission whenthe system’s initialization stage is completed upon boot-up.

• CPU Slow Down - When CPU fans or system fans are malfunctioning, thesystem will deactivate the CPU Clock line to decrease CPU utilization to thespeed upon detection of system overheat. This will prevent CPU damage fromsystem overheat. The CPU utilization will restore normal operations when tem-perature falls below a safe level.

• Auto Fan Off - The system fans will power off automatically even in sleepmode. This function reduces both energy consumption and system noise, andis a important feature to implement silent PC systems.

• Dual Function Power Button (requires ATX power supply): The system canbe in one of two states, one is Sleep mode and the other is the Soft-Off mode.Pushing the power button for less than 4 seconds places the system into Sleepmode. When the power button is pressed for more than 4 seconds, it enters theSoft-Off mode.

• Remote Ring On (requires external modem and ATX power supply): Thisallows a computer to be turned on remotely through an external modem. With thisbenefit on-hand, any user can access vital information from their computer fromanywhere in the world!

• Message LED (requires ACPI OS support): Chassis LEDs now act as infor-mation providers. Through the way a particular LED illuminates, the user candetermine the stage the computer is in. A simple glimpse provides useful infor-mation to the user.

Jumpers

III. INSTALLATION

Installation StepsBefore using your computer, you must complete the following steps:

1. Set Jumpers on the Motherboard2. Install System Memory Modules3. Install the Central Processing Unit (CPU)4. Install Expansion Cards5. Connect Ribbon Cables, Cabinet Wires, and Power Supply6. Setup the BIOS Software

1. JumpersSeveral hardware settings are made through the use of jumper caps to connect jumper

pins (JP) on the motherboard. See motherboard layout for locations of jumpers. The

jumper settings will be described numerically, such as [----], [1-2], [2-3] for no con-

nection, connect pins 1&2, and connect pins 2&3 respectively. Pin 1 for our mother-

boards is always on topPIN 1

or on the left PIN 1

when holding the motherboard with

the keyboard connector away from yourself. A “1” is written besides pin 1 on jumpers

with three pins. The jumpers will also be shown graphically such as to connect

pins 1&2 and to connect pins 2&3. Jumpers with two pins will be shown as

for Short (On) and for Open (Off). For manufacturing simplicity, the jump-

ers may be sharing pins from other groups. Use the diagrams in this manual instead of

following the pin layout on the board. Settings with two jumper numbers require that

both jumpers be moved together. To connect the pins, simply place a plastic jumper

cap over the two pins as diagramed.

WARNING! Computer motherboards, baseboards and components, such as SCSIcards, contain very delicate Integrated Circuit (IC) chips. To protect them againstdamage from static electricity, you should follow some precautions whenever youwork on your computer.

1. Unplug your computer when working on the inside.2. Use a grounded wrist strap before handling computer components. If you do

not have one, touch both of your hands to a safely grounded object or to ametal object, such as the power supply case.

3. Hold components by the edges and try not to touch the IC chips, leads orconnectors, or other components.

4. Place components on a grounded antistatic pad or on the bag that came withthe component whenever the components are separated from the system.

2. System Memory (SIMM & DIMM)This motherboard supports four 72-pin, 32-bit SIMMs (Single Inline Memory Mod-ules) of 4, 8, 16, 32, or 64MB to form a memory size between 8MB to 256MB. TheSIMMs can be either 60ns or 70ns Fast Page Mode (FPM) (Asymmetric or Sym-metric), or Enhanced Data Out (EDO) (BEDO & Parity are not supported). SIMMsmust be installed in pairs so that each Row (see Map of Motherboard for Row loca-tions) contains 64-bits of the same size and type of memory chips. One side (withmemory chips) of the SIMM module takes up half a Row on the motherboard.

Dual Inline Memory Modules (DIMMs) can be used when the SIMM sockets arenot used. Two sockets are available for 3.3Volt (power level) Unbuffered Synchro-nous DRAMs (SDRAM) or EDO DRAM of either 8, 16, 32, 64, or 128MB to forma memory size between 8MB to 256MB. One side (with memory chips) of theDIMM module takes up one row on the motherboard.

IMPORTANT: Memory speed setup is required through “Auto Configuration”in BIOS Chipset Setup of the BIOS SOFTWARE. If both 60ns and 70ns memoryare used, set “Auto Configuration” to 70ns. Do not use memory modules withmore than 24 chips per module. Modules with more than 24 chips exceed thedesign specifications of the memory subsystem and will be unstable.

Insert the module as shown. Because the number of pins are different on either sideof the breaks, the module will only fit in the orientation as shown. DRAM SIMMmodules have the same pin contact on both sides. SDRAM DIMM modules havedifferent pin contacts on each side and therefore have a higher pin density.

The notch on the DIMM module will shift between left, center, or right to identifythe type and also to prevent the wrong type to be inserted into the DIMM slot on themotherboard. You must ask your retailer for the specifications before purchasing.Four clock signals are supported on this motherboard.


3. Central Processing Unit (CPU)

The motherboard provides a 321-pin ZIF Socket 7 that is backwards compatiblewith ZIF Socket 5 processors. The CPU that came with the motherboard shouldhave a fan attached to it to prevent overheating. If this is not the case then purchasea fan before you turn on your system. Apply thermal jelly to the CPU top and theninstall the fan onto the CPU.

WARNING! Without a fan circulating air on the CPU and heat sinks, the CPUand/or heat sinks can overheat and cause damage to both the CPU and the moth-erboard. (See “CPU Cooling Fan Connector” at the end of this section.)

To install a CPU, first turn off your system and remove its cover. Locate the ZIFsocket and open it by first pulling the lever sideways away from the socket thenupwards to a 90-degree right angle. Insert the CPU with the correct orientation asshown. Use the notched corner of the CPU as your guide. The white dot shouldpoint towards the end the of the lever. Notice that there is a blank area where onehole is missing from that corner of the square array of pin holes and a “1” printed onthe motherboard next to that corner. Because the CPU has a corner pin for three ofthe four corners, the CPU will only fit in the one orientation as shown. The pictureis for reference only; you should have a CPU fan that will cover the face of the CPU.With the added weight of the CPU fan, no force is required to insert the CPU. Oncecompletely inserted, hold down on the fan and close the socket’s lever.

IMPORTANT: You must set jumpers for “CPU to BUS Frequency Ratio” andjumpers for “BUS Frequency Selection” depending on the CPU that you install.

4. Expansion Cards

Expansion Card Installation Procedure:1. Read your expansion card documentation on any hardware and software set-

tings that may be required to setup your specific card.

2. Set any necessary jumpers on your expansion card.

3. Remove your computer system’s cover.

4. Remove the bracket on the slot you intend to use.Keep the bracket for possible future use.

5. Carefully align the card’s connectors and press firmly.

6. Secure the card on the slot with the screw you removed in step 4.

7. Replace the computer system’s cover.

8. Edit the BIOS settings if necessary.(such as “IRQ xx Used By ISA: Yes” in PNP AND PCI SETUP)

9. Install the necessary software drivers for your expansion card.

Assigning IRQs for Expansion CardsSome expansion cards need to use an IRQ to operate. Generally an IRQ must beexclusively assigned to one use. In an standard design there are 16 IRQs availablebut most of them are already in use by parts of the system which leaves 6 free forexpansion cards.

Both ISA and PCI expansion cards may need to use IRQs. System IRQs are avail-able to cards installed in the ISA expansion bus first, and any remaining IRQs arethen used by PCI cards. Currently, there are two types of ISA cards. The originalISA expansion card design, now referred to as “Legacy” ISA cards, requires thatyou configure the card’s jumpers manually and then install it in any available slot onthe ISA bus. You may use Microsoft’s Diagnostic (MSD.EXE) utility included inthe Windows directory to see a map of your used and free IRQs. For Windows 95users, the “Control Panel” icon in “My Computer,” contains a “System” icon whichgives you a “Device Manager” tab. Double clicking on a specific device gives youthe “Resources” tab, which shows the Interrupt number and address. Make sure thatno two devices use the same IRQs or your computer will experience problems whenthose two devices are in use at the same time.

WARNING! Make sure that you unplug your power supply when adding orremoving expansion cards or other system components. Failure to do so maycause severe damage to both your motherboard and expansion cards.


III. INSTALLATIONTo simplify this process this motherboard has complied with the Plug and Play (PNP)specification which was developed to allow automatic system configuration when-ever a PNP-compliant card is added to the system. For PNP cards, IRQs are as-signed automatically from those available.

If the system has both Legacy and PNP ISA cards installed, IRQs areassigned to PNP cards from those not used by Legacy cards. The PCI and PNPconfiguration of the BIOS setup utility can be used to indicate which IRQs are beingused by Legacy cards. For older Legacy cards that does not work with the BIOS,you can contact your vendor for an ISA Configuration Utility.

An IRQ number is automatically assigned to PCI expansion cards after those usedby Legacy and PNP ISA cards. In the PCI bus design, the BIOS automaticallyassigns an IRQ to a PCI slot that has a card in it that requires an IRQ. To install aPCI card, you need to set something called the INT (interrupt) assignment. Since allthe PCI slots on this motherboard use an INTA #, be sure that the jumpers on yourPCI cards are set to INT A.

Assigning DMA Channels for ISA CardsSome ISA cards, both legacy and PnP, may also need to use a DMA (Direct MemoryAccess) channel. DMA assignments for this motherboard are handled the same wayas the IRQ assignment process described earlier. You can select a DMA channel inthe PCI and PnP configuration section of the BIOS Setup utility.

IMPORTANT: To avoid conflicts, reserve the necessary IRQs and DMAs for legacyISA cards (under PNP AND PCI SETUP of the BIOS SOFTWARE, choose Yes in IRQxx Used By ISA and DMA x Used By ISA for those IRQs and DMAs you want to reserve).

ISA Cards and Hardware MonitorThe onboard hardware monitor uses the address 290H-297H so legacy ISA cardsmust not use this address or else conflicts will occur.

6. BIOS SetupThe 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 ROMchip as described in detail in this section.

All computer motherboards provide a Setup utility program for specifying the sys-tem configuration and settings. If your motherboard came in a computer system, theproper configuration entries may have already been made. If so, invoke the Setuputility, as described later, and take note of the configuration settings for future refer-ence; in particular, the hard disk specifications.

If you are installing the motherboard, reconfiguring your system or you receive aRun Setup message, you will need to enter new setup information. This sectiondescribes how to configure your system using this utility.

The BIOS ROM of the system stores the Setup utility. When you turn on the com-puter, the system provides you with the opportunity to run this program. This ap-pears during the Power-On Self Test (POST). Press <Delete> to call up the Setuputility. If you are a little bit late pressing the mentioned key(s), POST will continuewith its test routines, thus preventing you from calling up Setup. If you still need tocall Setup, reset the system by pressing <Ctrl> + <Alt> + <Delete>, or by pressingthe Reset button on the system case. You can also restart by turning the system offand then back on again. But do so only if the first two methods fail.

When you invoke Setup, the CMOS SETUP UTILITY main program screen willappear with the following options:

A section at the bottom of the preceding screen displays the control keys for thisscreen. Take note of these keys and their respective uses.

Standard CMOS SetupStandard CMOS Setup allows you to record some basic system hardware configu-ration and set the system clock and error handling. If the motherboard is alreadyinstalled in a working system, you will not need to select this option anymore. How-ever, if the configuration stored in the CMOS memory on the board gets lost ordamaged, or if you change your system hardware configuration, you will need torespecify the configuration values. The configuration values usually get lost orcorrupted when the power of the onboard CMOS battery weakens.

The preceding screen provides you with a list of options. At the bottom of this screenare the control keys. Take note of these keys and their respective uses.

User-configurable fields appear in a different color. If you need information on theselected field, press <F1>. The help menu will then appear to provide you with theinformation you need. The memory display at the lower right of the screen is read-only and automatically adjusts accordingly.

NOTE: You can bypass the date and time prompts by creating an AUTOEXEC.BATfile. For information on how to create this file, refer to the MS-DOS manual.

Hard Disk DrivesThis field records the specifications for all non-SCSI hard disk drives installed inyour system. The onboard PCI IDE connectors provide Primary and Secondarychannels for connecting up to four IDE hard disks or other IDE devices. Each chan-nel can support up to two hard disks; the first of which is the “master” and thesecond is the “slave”.

Specifications for SCSI hard disks need not to be entered here since they operateusing device drivers and are not supported by any the BIOS. If you install either theoptional PCI-SC200 or PCI-SC860 SCSI controller card into the motherboard, seesection VI for instructions. If you install other vendor’s SCSI controller card, referto their respective documentations on how to install the required SCSI drivers.

For IDE hard disk drive setup, you can:• Use the Auto setting for detection during bootup.• Use the IDE HDD AUTO DETECTION in the main menu to automatically

enter the drive specifications.• Enter the specifications yourself manually by using the “User” option.

The entries for specifying the hard disk type include CYLS (number of cylinders),HEAD (number of read/write heads), PRECOMP (write precompensation), LANDZ(landing zone), SECTOR (number of sectors) and MODE . The SIZE field auto-matically adjusts according to the configuration you specify. The documentationthat comes with your hard disk should provide you with the information regardingthe drive specifications.

The MODE entry is for IDE hard disks only, and can be ignored for MFM and ESDIdrives. This entry provides three options: Normal, Large, LBA, or Auto (see below).Set MODE to the Normal for IDE hard disk drives smaller than 528MB; set it toLBA for drives over 528MB that support Logical Block Addressing (LBA) to allowlarger IDE hard disks; set it to Large for drives over 528MB that do not supportLBA. Large type of drive can only be used with MS-DOS and is very uncommon.Most IDE drives over 528MB support the LBA mode.

Auto detection of hard disks on bootupFor each field: Primary Master, Primary Slave, Secondary Master, and SecondarySlave, you can select Auto under the TYPE and MODE fields. This will enable autodetection of your IDE hard disk during bootup. This will allow you to change yourhard disks (with the power off) and then power on without having to reconfigureyour hard disk type. If you use older hard disks that do not support this feature, thenyou must configure the hard disk in the standard method as described earlier by the“User” option.

NOTE: After the IDE hard disk drive information has been entered into BIOS, newIDE hard disk drives must be partitioned (such as with FDISK) and then formattedbefore data can be read from and write on. Primary IDE hard disk drives must haveits partition set to active (also possible with FDISK).

NOTE: SETUP Defaults are noted in parenthesis next to each function heading.

A pop-up help menu will appear to provideyou with the information you need. <F5> loads the last set values, <F6> and <F7>loads the BIOS default values and Setup default values, respectively.


Details of BIOS Features SetupVirus Warning (Disabled)This field protects the boot sector and partition table of your hard disk against accidentalmodifications. Any attempt to write to them will cause the system to halt and display awarning message. If this occurs, you can either allow the operation to continue or use abootable virus-free floppy disk to reboot and investigate your system. This setting is rec-ommended because of conflicts with new operating systems or some programs. Installa-tion of these programs requires that you disable Virus Warning to prevent write errors.

BIOS Features

HDD Sequence SCSI/IDE First (IDE)When using both SCSI and IDE hard disk drives, IDE is always the boot disk usingdrive letter C (default setting of IDE ). This new feature allows a SCSI hard diskdrive to be the boot disk when set to SCSI. This allows multiple operating systems tobe used on both IDE and SCSI drives or the primary operating system to boot usinga SCSI hard disk drive.

Boot Sequence (C,A)This field determines where the system looks first for an operating system. Options areC,A; A,CDROM,C; CDROM,C,A; D,A; E,A; F,A; C only; LS/ZIP, C; and A,C. The setupdefault setting is to check first the hard disk and then the floppy disk drive; that is, C, A.

Boot Up Floppy Seek (Disabled)When enabled, the BIOS will seek drive A one time.

Floppy Disk Access Control (R/W)This allows protection of files from the computer system to be copied to floppy diskdrives by allowing the setting of Read Only to only allow reads from the floppy diskdrive but not writes. The setup default R/W allows both reads and writes.

IDE HDD Block Mode Sectors (HDD MAX)This field enhances hard disk performance by making multi-sector transfers insteadof one sector per transfer. Most IDE drives, except older versions, can utilize thisfeature. Selections are HDD MAX, Disabled, 2, 4, 8, 16, and 32.

Security Option (System)This field determines when the system prompts for the password. The default set-ting is System, where the system prompts for the User Password every time you bootup. The other option is Setup, where the system always boots up, and prompts forthe Supervisor Password only when the Setup utility is called up. You can specify apassword by using the Supervisor Password or User Password option from the mainscreen as explained later in this section.

PS/2 Mouse Function Control (Auto)The default of Auto allows the system to detect a PS/2 mouse on bootup. If detected,IRQ12 will be used for the PS/2 mouse. IRQ12 will be reserved for expansion cardsif a PS/2 mouse is not detected. Enabled will reserve IRQ12 for the PS/2 mouse, andthus other devices will not be able to use IRQ12.

PCI/VGA Palette Snoop (Disabled)Some display cards that are nonstandard VGA such as graphics accelerators or MPEGVideo Cards may not show colors properly. The setting Enabled should correct thisproblem. Otherwise leave this on the setup default setting of Disabled.

OS/2 Onboard Memory > 64M (Disabled)When using OS/2 operating systems with installed DRAM of greater than 64MB,you need to Enable this option otherwise leave this on the setup default of Disabled.......................................................................................................................................

Video ROM BIOS Shadow (Enabled)This field allows you to change the video BIOS location from ROM to RAM. Relocat-ing 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 otherexpansion cards with ROMs on them, you will need to know which addresses theROMs use to shadow them specifically. Shadowing a ROM reduces the memoryavailable between 640KB and 1024KB by the amount used for this purpose.

Boot Up NumLock Status (On)This field enables users to activate the Number Lock function upon system boot.

Typematic Rate Setting (Disabled)When enabled, you can set the two typematic controls listed next. Setup defaultsetting is Disabled.

Typematic Rate (Chars/Sec) (6)This field controls the speed at which the system registers repeated keystrokes. Op-tions range from 6 to 30 characters per second. Setup default setting is 6; othersettings are 8, 10, 12, 15, 20, 24, and 30.

Chipset Features SetupThe “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.


Details of Chipset Features SetupAuto Configuration (60ns DRAM)The default setting of 60ns DRAM sets the optimal timings for items 2 through 9 for60ns DRAM modules. If you are using 70ns DRAM modules, you must change thisitem to 70ns DRAM. See section III for DRAM installation information.

SDRAM CAS# Latency (3T)If you use ASUS SDRAM DIMM modules, you can set this to 2T for better perfor-mance, 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 missoccurs, the CPU will cancel this command. Some operating systems under certainsituations have a problem utilizing this feature so it is normally Disabled.

Passive Release (Enabled)This is a mechanism that allows concurrency of ISA/EISA cycles and CPU-to-PCIcycles. When this feature is enabled, the TXC will be possible to re-arbitrate PCIbus and allow the CPU to access PCI even when the PCEB has been granted the bus.

Delayed Transaction (Disabled)If Enabled, this frees the PCI Bus during CPU accessing of 8-bit ISA cards whichnormally consume about 50-60 PCI Clocks without PCI delayed transaction. If PCIBus Masters cannot use the PCI Bus, leave this on the default setting of Disabled forsome ISA cards that are not PCI 2.1 compliant.

Memory from 14MB and upor 15MB and up will be unavailable to the system because expansion cards can onlyaccess memory up to 16MB.....................................................................................................................................

Onboard FDC Controller (Enabled)When enabled, this field allows you to connect your floppy disk drives to the on-board floppy drive connector instead of a separate controller card. If you want to usea different controller card to connect the floppy drives, set this field to Disabled.

Onboard FDC Swap A & B (No Swap)This field allows you to reverse the hardware drive letter assignments of your floppydisk drives. Two options are available: Swap AB and No Swap (default). If you wantto switch drive letter assignments, set this field to Swap AB, and the swap will becontrolled by the onboard chipset.

Onboard Serial Port 1 (3F8H/IRQ4)Settings are 3F8H/IRQ4, 2F8H/IRQ3, 3E8H/IRQ4, 2E8H/IRQ10, and Disabled forthe onboard serial connector.

Onboard Serial Port 2 (2F8H/IRQ3)Settings are 3F8H/IRQ4, 2F8H/IRQ3, 3E8H/IRQ4, 2E8H/IRQ10, and Disabled forthe onboard serial connector.

Onboard Parallel Port (378H/IRQ7)This field sets the address of the onboard parallel port connector. You can select either3BCH / IRQ 7, 378H / IRQ 7, 278H / IRQ 5, or Disabled. If you install an I/O card witha parallel port, ensure that there is no conflict in the address assignments. The PC cansupport up to three parallel ports as long as there are no conflicts for each port.

Parallel Port Mode (ECP+EPP)This field allows you to set the operation mode of the parallel port. The settingNormal, allows normal-speed operation but in one direction only; EPP allows bidi-rectional parallel port operation at maximum speed; ECP allows the parallel port tooperate in bidirectional mode and at a speed faster than the maximum unidirectionaldata transfer rate; ECP+EPP allows normal speed operation in a two-way mode.

IDE HDD Auto DetectionThis “IDE HDD Auto Detection” option detects the parameters of an IDE hard diskdrive, and automatically enters them into the Standard CMOS Setup screen.

Up to four IDE drives can be detected, with parameters for each listed inside thebox. To accept the optimal entries, press <Y> or else select from the numbers dis-played under the OPTIONS field (2, 1, 3 in this case); to skip to the next drive, press<N>. If you accept the values, the parameters will appear listed beside the driveletter on the screen. The process then proceeds to the next drive letter. Pressing<N> to skip rather than to accept a set of parameters causes the program to enterzeros after that drive letter.

Remember that if you are using another IDE controller that does not feature En-hanced IDE support for four devices, you can only install two IDE hard disk drives.Your IDE controller must support the Enhanced IDE features in order to use Drive Eand Drive F. The onboard PCI IDE controller supports Enhanced IDE, with twoconnectors for connecting up to four IDE devices. If you want to use another con-troller that supports four drives, you must disable the onboard IDE controller in theChipset Features Setup screen.

When auto-detection is completed, the program automatically enters all entries youaccepted on the field for that drive in the Standard CMOS Setup screen. Skippedentries are ignored and are not entered in the screen.

If you are auto-detecting a hard disk that supports the LBA mode, three lines willappear in the parameter box. Choose the line that lists LBA for an LBA drive. Donot select Large or Normal.

The auto-detection feature can only detect one set of parameters for a particular IDEhard drive. Some IDE drives can use more than one set. This is not a problem if thedrive is new and empty.

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 parametersmanually 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, thedisk will not be readable. If the auto-detected parameters do not match the ones thatshould be used for your disk, do not accept them. Press <N> to reject the presentedsettings and enter the correct ones manually from the Standard CMOS Setup screen.

V. SUPPORT SOFTWARE

Desktop Management Interface (DMI)

Introducing the ASUS DMI Configuration UtilityThis motherboard supports DMI within the BIOS level and provides a DMI Con-figuration Utility to maintain the Management Information Format Database (MIFD).DMI is able to auto-detect and record information pertinent to a computer’s systemsuch as the CPU type, CPU speed, and internal/external frequencies, and memorysize. The onboard BIOS will detect as many system information as possible andstore those collected information in a 4KB block in the motherboard’s Flash EPROMand allow the DMI to retrieve data from this database. Unlike other BIOS software,the BIOS on this motherboard uses the same technology implemented for Plug andPlay to allow dynamic real-time updating of DMI information versus creating a newBIOS image file and requiring the user to update the whole BIOS. This DMI Con-figuration Utility also allows the system integrator or end user to add additionalinformation into the MIFD such as serial numbers, housing configurations, and ven-dor information. Those information not detected by the motherboard BIOS and hasto be manually entered through the DMI Configuration Utility and updated into theMIFD. This DMI Configuration Utility provides the same reliability as PnP updat-ing and will prevent the refreshing failures associated with updating the entire BIOS.

System RequirementsThe DMI Configuration Utility (DMICFG.EXE) must be used in real mode in orderfor the program to run, the base memory must be at least 180K. Memory managerslike HIMEM.SYS (required by windows) must not be installed. You can boot upfrom a system diskette without AUTOEXEC.BAT and CONFIG.SYS files, “REM”HIMEM.SYS in the CONFIG.SYS, or press <F5> during bootup to bypass yourAUTOEXEC.BAT and CONFIG.SYS files.


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 willshow the available keys for each screen. Press enter at the menu item to enter theright hand screen for editing. “Edit component” appears on top. The reversed colorfield is the current cursor position and the blue text are available for editing. Theorange text shows auto-detected information and are not available for editing. Theblue text “Press [ENTER] for detail” contains a second pop-up menu is available,use the + - (plus-minus) keys to change the settings. Enter to exit and save, ESC toexit and not save.

If the user has made changes, ESC will prompt you to answer Y or N. Enter Y to goback to the left-hand screen and save, enter N to go back to left-hand screen and notsave. If editing has not been made, ESC will send you back to the left hand menuwithout any messages.

NotesA heading, *** BIOS Auto Detect ***, appears on the right for each menu item on theleft side that has been auto detected by the system BIOS.

A heading, *** User Modified ***, will appear on the right for menu items that havebeen modified by the user.

Generally, there are three MIDI file formats available in the market,General MIDI, Extended MIDI and Basic MIDI. You can type “SET” at the DOSprompt and see the following line for the setting of the BLASTER environmentvariable:

MIDI=SYNTH:<1/2> MAP:<G/E/B>

Where:

SYNTH: 1 Specifies internal synthesizer (default)

2 Specifies audio hardware MIDI port

MAP: G Specifies General MIDI file format

E Specifies Extended MIDI file format (default)

B Specifies Basic MIDI file format

Maximum Recording Rates for the Audio HardwareThe sampling rate used for recording is largely influenced by your computer’s mainprocessor. To obtain 16-bit digital audio using Windows, the following maximumrecording rates are suggested.

SYSTEM RECORDING RATE386 and above Stereo - 44KHz

Mono - 44KHz386 SX and below Stereo - 22KHz

Mono - 44KHz

To obtain optimal performance, try configuring the audio hardware to use a highDMA (Direct Memory Access) channel under Windows. Refer to your audio hard-ware Getting Started Manual for more information on setting up the sound card touse a high DMA channel.
