III. INSTALLATION

Installation Steps

Before using your computer, you must complete the following steps:

1. Set Jumpers on the Motherboard

2. Install DRAM Modules

3. Install the Central Processing Unit (CPU)

4. Install Expansion Cards

5. Connect Ribbon Cables, Cabinet Wires, and Power Supply

6. Setup the BIOS Software

1. Jumpers

Several hardware settings are made through the use of jumper caps to connect jumper

pins (JP) on the motherboard. See "Map of the Motherboard" on page 4 for loca-

tions of jumpers. The jumper settings will be described numerically such as [----],

[1-2], [2-3] for no connection, connect pins 1&2, and connect pins 2&3 respec-

Pin 1

tively. Pin 1 for our motherboards is always on top

or on the left

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.

for Open

Jumpers with two pins will be shown as

for Short (On) and

(Off). For manufacturing simplicity, the jumpers 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 to-

gether. To connect the pins, simply place a plastic jumper cap over the two pins as

diagramed.

WARNING: Computer motheboards and components contain very delicate

Integrated Circuit (IC) chips. To protect the motherboard and other compo-

nents against damage from static electricity, you should follow some precau-

tions whenever you work on your computer.

1. Unplug your computer when working on the inside.

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

circuitry.

3. Use a grounded wrist strap before handling computer components.

4. Place components on a grounded antistatic pad or on the bag that came with

the component whenever the components are separated from the system.

HERE TO CLEAR CMOS) momentarily with a metallic object (3) Turn on your

computer, (4) Hold down <Delete> during bootup and enter BIOS setup to re-

enter user preferences.

Battery Test Jumper (For Service Use Only)

You can test the battery’s current by removing this jumper and attaching a cur-

rent meter to the pins. WARNING: You must unplug the power cord to your

power supply to ensure that there is no power to your motherboard. The

CMOS RAM containing BIOS setup information may be cleared by this

action. You should enter BIOS to “Load Setup Defaults” and re-enter any

user information after removing and reapplying this jumper.

Compatible Cyrix CPU Identification

The only Cyrix CPU that is supported on this motherboard is

labeled Cyrix 6x86 P166+ but must be Revision 2.7 and later.

Look on the underside of the CPU for the serial number. The

number should read G8DC6620A or larger.

3. Voltage Regulator Output Selection (VID0, 1, 2)

These jumpers set the voltage supplied to the CPU. Current Intel CPU's marked

"Pentium" has only a Single Power Plane and uses the standard 3.38 volts (STD)

or 3.5 volts (VRE). Currently Intel’s new Pentium P55C MMX 200MHz with

Dual Power Planes is supported at 2.8Volts. The voltage regulators will automati-

cally detect and switch between Single Power Plane and Dual Power Planes.

4. CPU External (BUS) Frequency Selection (FS0, FS1, FS2)

These jumpers tell 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).

5. CPU to BUS Frequency Ratio (BF0, BF1)

These jumpers set the frequency ratio between the Internal frequency of the CPU

and the External frequency (called the BUS Clock) within the CPU. These must

be set together with the above jumpers CPU External (BUS) Frequency Selection.

III. INSTALLATION

2. System Memory (SIMM)

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. The

SIMMs can be either 60ns or 70ns Fast Page Mode (FPM) (Asymmetric or Sym-

metric), or Enhanced Data Out (EDO) (BEDO & Parity are not supported). 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 mod-

ules. Mixing 32-bit non-parity DRAM (e.g. 8 chips) and 36-bit DRAM (e.g. 12

chips) will work minus the ECC feature.

SIMMs must be installed in pairs so that each Row (see Map of Motherboard for Row

locations) contains 64-bits of the same size and type of memory chips. One side (with

memory chips) of the SIMM module takes up half a Row on the motherboard.

IMPORTANT: Memory speed setup is required through "Auto Configura-

tion" in BIOS Chipset Setup of the BIOS SOFTWARE. If both 60ns and 70ns

memory are used, set "Auto Configuration" to 70ns. Do not use memory mod-

ules with more than 24 chips per module. Modules with more than 24 chips

exceed the design specifications of the memory subsystem and will be unstable.

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 circulating air on the CPU and heat sinks, the

CPU and/or heat sinks can overheat and cause damage to both the CPU and the

motherboard. (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 ZIF

socket and open it by first pulling the lever sideways away from the socket then

upwards to a 90-degree right angle. Insert the CPU with the correct orientation as

shown. Use the notched corner of the CPU with the white dot as your guide. The

white dot should point towards the end the of the lever. Notice that there is a blank

area where one hole is missing from that corner of the square array of pin holes and

a "1" printed on the motherboard next to that corner. Because the CPU has a corner

pin for three of the four corners, the CPU will only fit in the one orientation as

shown. The picture is 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. Once completely inserted, hold down on the fan and close the

socket's lever.

IMPORTANT: You must set jumpers for "CPU to BUS Frequency Ratio" and

jumpers for "BUS Frequency Selection" depending on the CPU that you install.

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:

1. Read the documentation for your expansion 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. Setup the BIOS 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 Cards

Some expansion cards need to use an IRQ to operate. Generally an IRQ must be

exclusively assigned to one use. In an standard design there are 16 IRQs available

but most of them are already in use by parts of the system which leaves 6 free for

expansion cards.

ASUS HX97 User’s Manual

Download from Www.Somanuals.com. All Manuals Search And Download.

III. INSTALLATION

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 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.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. Double clicking on a specific device give you

"Resources" tab which shows the Interrupt number and address. Make sure that no

two devices use the same IRQs or your computer will experience problems when

those two devices are in use at the same time.

To 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 are

assigned to PNP cards from those not used by Legacy cards. The PCI and PNP

configuration of the BIOS setup utility can be used to indicate which IRQs are being

used 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 used

by Legacy and PNP ISA cards. In the PCI bus design, the BIOS automatically

assigns an IRQ to a PCI slot that has a card in it that requires an IRQ. To install a

PCI card, you need to set something called the INT (interrupt) assignment. Since all

the PCI slots on this motherboard use an INTA #, be sure that the jumpers on your

PCI cards are set to INT A.

Assigning DMA Channels for ISA Cards

Some ISA cards, both Legacy and PNP may also need to use a DMA (Direct Memory

Access) channel. DMA assignments for this motherboard are handled the same way

as the IRQ assignment process described above. You can select a DMA channel in

the PCI and PNP configuration section of the BIOS Setup utility.

IMPORTANT: Choose "Yes" for those IRQ's and DMA's you wish to reserve

for Legacy (Non-PnP) ISA expansion cards in “IRQ xx Used By ISA” and “DMA

x Used By ISA” of the PNP and PCI Setup in the BIOS SOFTWARE section,

otherwise conflicts may occur.

using device drivers and are not supported by any the BIOS. If you install the

optional PCI-SC200 SCSI controller card into the motherboard (see section VI for

instructions). If you install other vendor’s SCSI controller card, please refer to 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 documentation

that comes with your hard disk should provide you with the information regarding

the drive specifications.

The MODE entry is for IDE hard disks only, and can be ignored for MFM and ESDI

drives. This entry provides three options: Normal, Large, LBA, or Auto (see be-

low). Set MODE to the Normal for IDE hard disk drives smaller than 528MB; set

it to LBA for drives over 528MB that support Logical Block Addressing (LBA) to

allow larger IDE hard disks; set it to Large for drives over 528MB that do not sup-

port LBA. Large type of drive can only be used with MS-DOS and is very uncom-

mon. Most IDE drives over 528MB support the LBA mode.

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 drives during bootup. This will allow you to change your

hard drives (with the power off) and then power on without having to reconfigure

your hard drive type. If you use older hard drives which do not support this feature,

then you must configure the hard drive in the standard method as described above

by the "User" option.

NOTE: After the IDE hard disk drive information has been entered into BIOS, new

IDE hard disk drives must be partitioned (such as with FDISK) and then formatted

before data can be read from and write on. Primary IDE hard disk drives must have

its partition set to active (also possible with FDISK).

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

Drive A / Drive B (None)

These fields record the types of floppy disk drives installed in your system. The

available options for drives A and B are: 360KB, 5.25 in.; 1.2MB, 5.25 in.; 720KB,

3.5 in.; 1.44MB, 3.5 in.; 2.88MB, 3.5 in.; None

To enter the configuration value for a particular drive, highlight its corresponding

field and then select the drive type using the left- or right-arrow key.

Floppy 3 Mode Support (Disabled)

This is the Japanese standard floppy drive. The standard stores 1.2MB in a 3.5"

diskette. This is normally disabled but you may choose from either: Drive A, Drive

B, Both, and Disabled

Video (EGA/VGA)

Set this field to the type of video display card installed in your system. The options

are: EGA/VGA, Mono (for Hercules or MDA), CGA 40, and CGA 80. If you are

using a VGA or any higher resolution card, choose the “EGA/VGA” option.

Halt On (All Errors)

This field determines which types of errors will cause the system to halt. Choose from

All Errors, No Errors, All, But Keyboard, All, But Diskette, and All, But Disk/Key.

BIOS Features Setup

This “BIOS Features Setup” option consists of configuration entries that allow you

to improve your system performance, or let you set up some system features accord-

ing to your preference. Some entries here are required by the motherboard’s design

to remain in their default settings.

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

Details of BIOS Features Setup

Virus Warning (Disabled)

This field protects the boot sector and partition table of your hard disk against acci-

dental modifications. Any attempt to write to them will cause the system to halt and

display a warning message. If this occurs, you can either allow the operation to

continue or use a bootable virus-free floppy disk to reboot and investigate your

system. This setting is recommended because conflicts with new operating sys-

tems. Installation of new operating systems require that you disable this to prevent

write errors.

CPU Internal Cache

These fields allow you to Enable (default) or Disable the CPU’s “Level 1” primary

cache. Caching allows better performance.

External Cache (Enabled)

These fields allow you to choose from the default of Enable or choose Disable to

turn on or off the CPU’s Level 2 built-in cache.

Quick Power On Self Test (Enabled)

This field speeds up the Power-On Self Test (POST) routine by skipping retesting a

second, third, and forth time. Setup default setting for this field is Enabled. A

complete test of the system is done on each test.

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. Options

are A,CDROM,C; CDROM,C,A; A,C; C,A The setup default setting is to check first

the hard disk and then the floppy drive; that is, C, A.

Boot Up Floppy Seek (Disabled)

When enabled, the BIOS will seek the floppy "A" drive one time.

Floppy Disk Access Control (R/W)

This allows protection of files from the computer system to be copied to floppy

drives by allowing the setting of Read Only to only allow reads from the floppy 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 instead

of one sector per transfer. Most IDE drives, except older versions, can utilize this

feature. 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 boot

up. The other option is Setup, where the system always boots up, and prompts for

the Supervisor Password only when the Setup utility is called up. You can specify a

password by using the Supervisor Password or User Password option from the main

screen 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 de-

tected, IRQ12 will be used for the PS/2 Mouse. IRQ12 will be reserved for expan-

sion cards if a PS/2 Mouse is not detected. Disabled will reserve IRQ12 for expan-

sion cards and therefore the PS/2 Mouse will not function.

PCI/VGA Palette Snoop (Disabled)

Some display cards that are nonstandard VGAsuch as graphics accelerators or MPEG

Video Cards may not show colors properly. The setting Enabled should correct this

problem. 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 to DC000-DFFFF (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.

Boot Up NumLock Status (On)

This field enables users to activate the Number Lock function upon system boot.

Boot Up System Speed (High)

This has no function and should be left on the setup default.

Typematic Rate Setting (Disabled)

When enabled, you can set the two typematic controls listed next. Setup default

setting is Disabled.

Typematic Rate (Chars/Sec) (6)

This field controls the speed at which the system registers repeated keystrokes.

Options range from 6 to 30 characters per second. Setup default setting is 6; other

settings are 8, 10, 12, 15, 20, 24, and 30.

Typematic Delay (Msec) (250)

This field sets the time interval for displaying the first and second characters. Four

delay rate options are available: 250, 500, 750, and 1000.

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 15M - 16M

Enabling this features reserves 15MB to 16MB memory address space to ISA ex-

pansion cards that specifically require this setting. This makes the memory from

15MB and up unavailable to the system. Expansion cards can only access memory

up to 16MB. The default is Disabled.

[DRAM and ECC]

If all your DRAM modules have parity chips (e.g. 8 chips + 4 parity chips), they are

considered 36bits. This motherboard sums the memory per bank and therefore two

modules will give 72bits and the following will be displayed:

If your DRAM modules do not have parity chips (e.g. 8 chips), they are considered

32bits and the following will be displayed instead:

The default of Disabled for Memory parity SERR# (NMI) will not show memory

errors on your monitor. When using parity DRAM modules, you can select from the

default of Parity or ECC (Error Checking and Correcting) to correct 1 bit memory

errors that may occur in the memory. (See pages 12-13 for more information on

DRAM memory modules.)

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

use a different controller card to connect the floppy drives, set this field to Disabled.

Onboard FDC Swap A & B (No Swap)

This field reverses the drive letter assignments of your floppy disk drives. Two

options are available: No Swap and Swap AB. If you want to switch drive letter

assignments, set this field to Swap AB, and the swap will be controlled in hardware.

This works separately from the BIOS Features floppy disk swap feature. It is func-

tionally the same as physically interchanging the connectors of the floppy disk drives.

Onboard Serial Port 1 (3F8H/IRQ4)

Settings are 3F8H/IRQ4, 2F8H/IRQ3, 3E8H/IRQ4, 2E8H/IRQ10, and Disabled for

the onboard serial connector.

Onboard Serial Port 2 (2F8H/IRQ3)

Settings are 3F8H/IRQ4, 2F8H/IRQ3, 3E8H/IRQ4, 2E8H/IRQ10, and Disabled for

the onboard serial connector.

Onboard Parallel Port (378H/IRQ7)

This field sets the address of the onboard parallel port connector. You can select

either: 3BCH / IRQ 7, 378H / IRQ 7, 278H / IRQ 5, Disabled. If you install an I/O

card with a parallel port, ensure that there is no conflict in the address assignments.

The PC can support 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 setting

Normal, allows normal-speed operation but in one direction only; EPP allows bidi-

rectional parallel port operation at maximum speed; ECP allows the parallel port to

operate in bidirectional mode and at a speed faster than the maximum data transfer

rate; ECP+EPP allows normal speed operation in a two-way mode.

ECP DMA Select (3)

This selection is available only if you select ECP or ECP+EPP in the

Parallel Port Mode. Select either DMA Channel 1, 3, or Disable.

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. See section III of the baseboard manual for the IrDA-compliant

infrared module connector.

Onboard PCI IDE Enable (Both)

You can select to enable the Primary IDE channel, Secondary IDE channel, Both, or

Disable both channels (for systems with only SCSI drives).

IDE 0 Master/Slave Mode, IDE 1 Master/Slave Mode

Each channel (0 and 1) has both a master and a slave making four IDE devices

possible. Because each IDE device may have a different Mode timing (0, 1, 2, 3, 4),

it is necessary for these to be independent. The default setting of Auto will allow

auto-detection to ensure the optimal performance.

Power Management Setup

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

Power Management (User Define)

This field acts as the master control for the power management modes. Max Saving

puts the system into power saving mode after a brief period of system inactivity;

Min Saving is almost the same as Max Saving except that this time the system inac-

tivity period is longer; Disabled disables the power saving features; User Defined

allows you to set power saving options according to your preference.

IMPORTANT: Advanced Power Management (APM) should be installed to

keep the system time updated when the computer enters suspend mode acti-

vated by the BIOS Power Management. For DOS environments, you need to

add DEVICE=C:\DOS\POWER.EXE in you CONFIG.SYS. For Windows 3.x

and Windows 95, you need to install Windows with the APM feature. Abattery

and power cord icon labeled "Power" will appear in the "Control Panel."

Choose "Advanced" in the Power Management Field.

Video Off Method (V/H SYNC + Blank)

This field defines the video off features. Three options are available: V/H SYNC +

Blank, DPMS, and Blank Only. The first option, which is the default setting, blanks

the screen and turns off vertical and horizontal scanning; DPMS (Display Power

Management System) allows the BIOS to control the video display card if it sup-

ports the DPMS feature; Blank Screen only blanks the screen. Use the latter for

monitors that do not support the “Green” (no power management) feature. NOTE:

Screen saver software does not work with this feature. While the monitor is shut off,

this software cannot display.

Suspend Switch

This field enables or disables the SMI connector on the motherboard. This connec-

tor connects to the lead from the Suspend switch mounted on the system case. De-

fault setting for this field is Enabled.

PM Timers

This section controls the time-out settings for the Power Management scheme. The

fields included in this section are “HDD Power Down”, which places the hard disk

into its lowest power consumption mode, and the Doze, Standby and Suspend sys-

tem inactivation modes.

The system automatically “wakes up” from any power saving mode when there is

system activity such as when a key is pressed from the keyboard, or when there is

activity detected from the enabled IRQ channels.

HDD Power Down shuts down any IDE hard disk drives in the system after a pe-

riod of inactivity. This time period is user-configurable to 1-15 Mins or Disable.

This feature does not affect SCSI hard drives.

The Doze Mode, Standby Mode, and Suspend Mode fields set the period of time

after which each of these modes activate. At Max Saving, these modes activate

sequentially (in the given order) after one minute; at Min Saving after one hour.

PM Events

This section sets the wake-up call of the system. If activity is detected from any

enabled IRQ channels in the left-hand group, the system wakes up from suspended

mode. You can enable power management for IRQs 3 ~ 15 individually in the list at

the right of the screen. The power management feature will work on the enabled

IRQ channels.

Take note that a Microsoft serial mouse or compatible will use either COM1 (IRQ4)

or COM2 (IRQ3), and a PS/2 mouse will use IRQ12. If you know which IRQ your

mouse is using, you can enable the Wake-up Event for that IRQ here and the system

will wake up when you move the mouse or click its button.

.......................................................................................................................................

Sleep Items (IRQ3-IRQ15)

You can individually Enable or Disable each IRQ to include in the sleep function.

IRQ8 (Real Time Alarm) is usually set to Disable so that any software alarm clock

or event calendar can wake up the system.

IRQ xx Used By ISA (No/ICU)

These fields indicate whether or not the displayed IRQ for each field is being used

by a Legacy (non-PnP) ISA card. Two options are available: No/ICU and Yes. The

first option, the default value, indicates either that the displayed IRQ is not used or

an ISA Configuration Utility (ICU) is being used to determine if an ISA card is

using that IRQ. If you install a Legacy ISA card that requires a unique IRQ, and you

are not using an ICU, you must set the field for that IRQ to Yes. For example: If you

install a Legacy ISAcard that requires IRQ 10, then set IRQ10 Used By ISA to Yes.

......................................................................................................................................

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. If you install a Legacy ISA card that requires a unique DMA

channel, and you are not using an ICU, you must set the field for that channel to Yes.

ISA MEM Block BASE (No/ICU)

This field allows you to set the base address and block size of a Legacy ISA card that

uses any memory segment within the C800, CC00, D000, D400, D800, and DC00

address range. If you have such a card, and you are not using an ICU to specify its

address range, select a base address from the six available options; the ISA MEM

Block SIZE field will then appear for selecting the block size. If you have more than

one Legacy ISA card in your system that requires to use this address range, you can

increase the block size to either 8K, 16K, 32K, or 64K. If you are using an ICU to

accomplish this task, leave ISA MEM Block BASE to its default setting of No/ICU.

Desktop Management Interface (DMI)

Introducing the ASUS DMI Configuration Utility

This 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 system

such as the CPU type, CPU speed, and internal/external frequencies, and memory

size. The onboard BIOS will detect as many system information as possible and

store those collected information in a 4KB block in the motherboard’s Flash EPROM

and 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 and

Play to allow dynamic real-time updating of DMI information versus creating a new

BIOS 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 additional

information into the MIFD such as serial numbers, housing configurations, and ven-

dor information. Those information not detected by the motherboard BIOS and has

to be manually entered through the DMI Configuration Utility and updated into the

MIFD. 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 Requirements

The DMI Configuration Utility (DMICFG.EXE) must be used in real mode in order

for the program to run, the base memory must be at least 180K. Memory managers

like HIMEM.SYS (required by windows) must not be installed. You can boot up

VI. ASUS PCI-SC200 SCSI Card

SCSI BIOS and Drivers

Aside from the system BIOS, the Flash memory chip on the motherboard also con-

tains the SCSI BIOS. This SCSI BIOS works in conjunction with the optionalASUS

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

SCSI BIOS directly supports SCSI hard disks under the DOS, Windows and OS/2

environments. It also uses device drivers from the DOS floppy disk included in the

PCI-SC200 controller card package to support hard disks and other SCSI devices

working under DOS, Windows, Windows NT, Novell NetWare and OS/2. These

drivers provide higher performance than the direct BIOS support. To use these

drivers, you must install them into your system and add them to your system con-

figuration files. Driver support for SCSI devices used with SCO UNIX is also pro-

vided. These drivers are included in the second SCO UNIX floppy disk. Windows

95 support is also available using the device drivers included within the Windows

software. The ASUS PCI-SC200 is a Plug and Play adapter that is auto detected by

BIOS and current operating systems that support Plug and Play features.

For information about these drivers and their usage, see the Readme files included

in the driver packages. You can print out the contents of these files using any text

editor program.

The next few pages will instruct you on the installation of the ASUS PCI-SC200

Fast SCSI Card.

VI. ASUS PCI-SC200 SCSI Card

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 com-

plete 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. You also have the additional option of connecting external SCSI devices to the

external SCSI-2 connector on the card.

If you get the ASUS PCI-SC200 later on as an option, you will need to install it

yourself. The setup procedure is explained here.

Setting Up the ASUS PCI-SC200

There are two jumper settings you may need to make on the card to set it up. One

setting assigns the PCI INT interrupt, the other sets the card’s termination.

VI. ASUS PCI-SC200 SCSI Card

Setting the INT Assignment

You must use PCI INT A setting in order to properly assign the card's interrupt. On

theASUS 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.

Terminator Settings

SCSI devices are connected together in a “chain” by cables. Internal devices con-

nect to the ASUS PCI-SC200 with a fifty-pin flat ribbon cable. External devices

connect to the external port with a SCSI-2 cable. If there are more than one internal

or external devices, additional devices are connected with cables to form a “daisy

chain.” The SCSI chain must be “terminated” at both ends, or the devices in the

chain will not work properly.

Terminated (Default)

Not Terminated

Terminator Setting (Terminated / Not Terminated)

Many SCSI devices use a set of terminating resistors to terminate the device. The

ASUS PCI-SC200 has “active” termination that you set using jumper JP5. If you

need to terminate theASUS PCI-SC200, you do it by setting the jumper. The are two

settings, "terminated" and "not terminated," as shown below.

VI. ASUS PCI-SC200 SCSI Card

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.

SCSI ID Numbers

All SCSI devices, including the ASUS PCI-SC200 interface card must have a SCSI

identification number that is not in use by any other SCSI device. There are eight

possible ID numbers, 0 through 7. The ASUS PCI-SC200 has a fixed SCSI ID of 7.

You can connect up to seven SCSI devices to the interface card. You must set a SCSI

ID number for each device. SCSI devices vary in how they set the ID number. Some

use jumpers, others have some kind of selector switch. Refer to the manual for any

device you install for details on how to set its ID number.
