3.3 Hardware Setup Procedure

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

• Check Motherboard Settings

• Install Memory Modules

• Install the Central Processing Unit (CPU)

• Install Expansion Cards

• Connect Ribbon Cables, Panel Wires, and Power Supply

3.4 Motherboard Settings

This section explains in detail how to change your motherboard’s function settings
through the use of switches and/or jumpers.

WARNING! Computer motherboards and expansion cards contain very delicate Inte-

grated Circuit (IC) chips. To protect them against damage from static electricity, you
should follow some precautions whenever you work 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 a metal object, such as
the power supply case.

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

5. Ensure that the ATX power supply is switched off before you plug in or remove the
ATX power connector on the motherboard.

Motherboard Feature Settings (DSW)

Besides jumper settings, some of the motherboard’ s onboard functions are adjusted
through the DIP switches. The white block represents the switch’s position. The

3.5 System Memory (DIMM)

NOTE: No hardware or BIOS setup is required after adding or removing memory.
This motherboard uses only Dual Inline Memory Modules (DIMMs). S ockets are

available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Ac-
cess Memory (SDRAM) of 16, 32, 64, 128MB, or 256MB. to form a memory size
between 16MB and 768MB. One side (with memory chips) of the DIMM takes up
one row on the motherboard.

To use the chipset’s Error Checking and Correction (ECC) feature, you must use a
DIMM with 9 chips per side (standard 8 chips/side + 1 ECC chip).

Memory speed setup is recommended through Configure SDRAM T iming by SPD
(see 4.4.2 Advanced Chipset Setup).

Install memory in any combination as follows:

3. H/W SETUP

IMPORTANT: DIMMs must be inserted in the following sequence: DIMM1,

DIMM2, DIMM3. That is, if you intend to initially use one DIMM, use DIMM1
first. Then when you are ready for a second DIMM, use DIMM2, and so on. If
this sequence is not followed, system instability may be experienced.

3.7. 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.

3.7.1 Expansion Card Installation Procedure

1. Read the documentation for your expansion card and make any necessary hard­ware or software settings for your expansion card, such as jumpers.

2. Remove your computer system’s cover and the bracket plate on the slot you
intend to use. Keep the bracket for possible future use.

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

4. Secure the card on the slot with the screw you removed above.

5. Replace the computer system’s cover.

6. Set up the BIOS if necessary
(such as IRQ xx Used By ISA: Yes in PNP AND PCI SETUP)

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

3.7.2 Assigning IRQs for Expansion Cards

IMPORTANT: Interrupt requests are shared as shown by the following table:

INT-A INT-B INT-C INT-D

PCI slot 1 shared — — —
PCI slot 2 — — — —
PCI slot 3 — — shared —
PCI slot 4 — — — shared
PCI slot 5 shared — — —
AGP slot shared — — —
Onboard USB controller — — — shared
Onboard AC’97/MC’97 codec/AMR — — shared —

3. H/W SETUP

Expansion Cards

If using PCI cards on shared slots, make sure that the drivers support “Share IRQ” or
that the cards do not need IRQ assignments. Conflicts will arise between the two
PCI groups that will make the system unstable or cards inoperable.

ASUS K7M User’s Manual 31

Some expansion cards need to use an IRQ to operate. Generally, an IRQ must be
exclusively assigned to one use. In a standard design, there are 16 IRQs available
but most of them are already in use, leaving 6 IRQs free for expansion cards. If your
motherboard has PCI audio onboard, an extra IRQ will be used, leaving 5 IRQs
free. If your motherboard has ISA audio onboard, an extra 3 IRQs will be used,
leaving 3 IRQs free.

Both ISA and PCI expansion cards may require IRQs. System IRQs are available to
cards installed in the ISA expansion bus first, then any remaining IRQs are available
to 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 an available slot on the ISA bus. T o
see a map of your used and free IRQs in W indows 98, the Control Panel icon in My
Computer, contains a System icon, which gives you a Device Manager tab. Double-
clicking on a specific hardware device gives you the Resources tab which shows the

Expansion Cards

3. H/W SETUP

Interrupt number and address. Make sure that no two devices use the same IRQ or
your computer will experience problems when those two devices are in use at the
same time.

3. HARDWARE SETUP

To simplify this process, this 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. 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 do 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 PCI cards that require an IRQ. To install a PCI card, you need to set an 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.

3.7.3 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 earlier. You can select a DMA channel in
the PCI and PnP configuration section of the BIOS Setup utility.

IMPORTANT: To avoid conflicts, reserve the necessary IRQs and DMAs for legacy
ISA cards (see 4.4.4 Plug and Play Setup for those IRQs and DMAs you want to
reserve).

32 ASUS K7M User’s Manual

3. HARDWARE SETUP

3.7.4 ISA Cards and Hardware Monitor

The onboard hardware monitor uses the address 290H-297H so legacy ISA cards
must not use this address or else conflicts will occur.

There are two types of AMR, one defined as primary and another de­fined as secondary. This motherboard uses the primary channel so that a secondary
AMR can coexist without the need to disable the onboard CODEC. The motherboard’ s
onboard CODEC must be disabled when using a primary AMR.

This lead is for a chassis designed for chassis intrusion detection. After-market
toggle switches may also be installed to the chassis panel or on any removable
components. Two wires should be available from the chassis to connect to this
lead. When any chassis component is removed, the contact should open and the
motherboard will record a chassis intrusion event. The event can then be pro­cessed by software, such as LDCM. If the chassis intrusion lead is not used, a

jumper cap must be placed over the pins to prevent unnecessary power loss.

24) ATX Power Switch Lead (2-pin PWRSW)

The system power is controlled by a momentary switch connected to this lead.
Pressing the button once will switch the system between ON and SOFT OFF.

Pushing the switch while in the ON mode for more than 4 seconds will turn the
system off. The system power LED shows the status of the system’s power.

25) System Management Interrupt Lead (2-pin SMI)

This allows the user to manually place the system into a suspend mode or “Green”
mode, where system activity is decreased to save electricity and expand the life
of certain components when the system is not in use. This 2-pin connector con­nects to the case-mounted suspend switch. If you do not have a switch for the
connector, you may use the “Turbo Switch.” SMI is activated when it detects a
short to open moment and therefore leaving it shorted will not cause any prob­lems. This may require one or two presses depending on the position of the
switch. W ake-up can be controlled by settings in the BIOS but the keyboard will
always allow wake-up (the SMI lead cannot wake up the system).

4.2. BIOS Setup Program

This motherboard supports a programmable EEPROM that can be updated using the
provided utility as described in 4.1 Managing and Updating Your BIOS.

The utility is used if you are installing a motherboard, reconfiguring your system, or
prompted to “Run Setup”. This section describes how to configure your system
using this utility.

Even if you are not prompted to use the Setup program, at some time in the future
you may want to change the configuration of your computer . For example, you may
want to enable the Supervisor Password Feature or make changes to the power man­agement settings. It will then be necessary to reconfigure your system using the
BIOS Setup program so that the computer can recognize these changes and record
them in the CMOS RAM of the EEPROM.

The EEPROM on the motherboard stores the Setup utility. When you start up the
computer, the system provides you with the opportunity to run this program. This
appears during the Power-On Self T est (POST). Pr ess <Delete> to call up the Setup
utility . If you are a little bit late in pressing the mentioned key , POST will continue
with its test routines, thus preventing you from calling up Setup. If you still need to
call Setup, restart the system by pressing <Ctrl> + <Alt> + <Delete>, or by pressing
the Reset button on the system chassis. You can also restart by turning the system off
and then back on again, but do so only if the first two methods fail.

The Setup program has been designed to make it as easy to use as possible. It is a
menu-driven program, which means you can launch the various pop-up menus and
make your selections among the predetermined choices.

NOTE: Because the BIOS software is constantly being updated, the following
BIOS screens and descriptions are for reference purposes only and may not re­flect your BIOS screens exactly.

slots. Available options: [Auto] [Slot1] [Slot2] [Slot3] [Slot4] [Slot5]

OffBoard PCI IDE Primary/Secondary IRQ [Disabled]

This feature selects the interrupt routing for add-on PCI IDE devices. A single-func­tion PCI device can only use INTA# pin. Multi-function PCI devices can use all the
pins. The option [Hardwired] means, instead of leaving the interrupt routing to the
control of the BIOS, the interrupt request lines on the add-on PCI IDE card are
wired to the ISA interrupt controller. NOTE: These two fields are only accessible
when you assign a slot to the OffBoard PCI IDE Card. Available options: [Dis­abled] [INTA] [INTB] [INTC] [INTD] [Hardwired]

DMA Channel x [PnP]

These fields indicate whether the displayed DMA channel for each field is being
used by a PnP card or a legacy (non-PnP) ISA card. If you install a legacy ISA card
that requires a unique DMA channel, you must set the field for that channel to [ISA/
EISA].

IRQ xx [PCI/PnP]

These fields indicate whether the displayed IRQ for each field is being used by a
PnP card or legacy (non-PnP) ISA card. If you install a legacy ISA card that requires
a unique IRQ, you must set the field for that IRQ to [ISA/EISA]. For example: If
you install a legacy ISA card that requires IRQ 10, then set IRQ10 to [ISA/EISA].

Reserved Memory Size [Disabled]
Reserved Memory Address

This field allows you to set the base address and block size of a legacy ISA card that
uses any memory segment within the C0000 and DFFFH address range. If you have
such a card, and you are not using an ISA Configuration Utility (ICU) to specify its
