•Power management logic.
•Real-Time Clock.
•16-bit counters/timers based on 82C54.
Accelerated Graphics Port (A.G.P.)
The Accelerated Graphics Port (A.G.P.) is a high-performance interconnect for graphic-
intensive applications, such as 3D applications. A.G.P. is independent of the PCI bus

10
and is intended for exclusive use with graphical-display devices. A.G.P. provides these
performance features:
•Pipelined-memory read and write operations that hide memory access latency.
•Demultiplexing of address and data on the bus for near 100 percent bus efficiency.
•AC timing for 133 MHz data transfer rates, allowing data throughput of 500
MBYTES/sec.
•A.G.P. complies with the 66 MHz PCI specification.
Universal Serial Bus (USB)
The motherboard has two USB ports; one USB peripheral can be connected to each
port. For more than two USB devices, an external hub can be connected to either port.
The motherboard fully supports the universal host controller interface (UHCI) and uses
UHCI-compatible software drivers. USB features include:
•Self-identifying peripherals that can be plugged in while the computer is running.
•Automatic mapping of function to driver and configuration.
•Supports isonchronous and asynchronous transfer types over the same set of wires.
•Supports up to 127 physical devices.
•Guaranteed bandwidth and low latencies appropriate for telephony, audio, and other
applications.
•Error-handling and fault-recovery mechanisms built into the protocol.
IDE Support
The motherboard has two independent bus-mastering PCI IDE interfaces. These
interfaces support PIO Mode 3, PIO Mode 4, ATAPI devices (e.g., CD-ROM), and Ultra
DMA/33 synchronous- DMA mode transfers. The BIOS supports logical block
addressing (LBA) and extended cylinder head sector (ECHS) translation modes. The
BIOS automatically detects the IDE device transfer rate and translation mode.
Programmed I/O operations usually require a substantial amount of processor
bandwidth. However, in multitasking operating systems, the bandwidth freed by bus
mastering IDE can be devoted to other tasks while disk transfers are occurring.
Real-Time Clock, CMOS RAM and Battery
The real-time clock is compatible with DS1287 and MC146818 components. The clock
provides a time-of-day clock and a multicentury calendar with alarm features and
century rollover. The realtime clock supports 256 bytes of battery-backed CMOS SRAM
in two banks that are reserved for BIOS use.
The time, date, and CMOS values can be specified in the Setup program. The CMOS
values can be returned to their defaults by using the Setup program.

11
An external coin-cell battery powers the real-time clock and CMOS content. When the
computer is not plugged into a wall socket, the battery has an estimated life of three
years. When the computer is plugged in, the 3.3 V standby current from the power
supply extends the life of the battery.
Super I/O Controller
The SMC 37C672 is an ISA Plug and Play compatible multifunction I/O device that
provides the following features:
•Two Serial Ports with high speed 16C550 compatible enhanced UARTs.
•Multimode bidirectional parallel port
•Floppy disk controller.
•Keyboard and mouse controller.
•Supports an IrDA and Consumer IR-compliant infrared interface.
By default, the I/O controller interfaces are automatically configured during boot up. The
I/O controller can also be manually configured in the Setup program.
Serial Ports
Two 9-pin D-Sub serial port connectors are located on the back panel and are
compatible with 16450 and 16550A UARTs.
Parallel Ports
The connector for the multimode bidirectional parallel port is a 25-pin D-Sub connector
located on the back panel. In the Setup program, the parallel port can be configured for
the following:
•Compatible (standard mode).
•Bidirectional (PS/2 compatible).
•Extended Parallel Port (EPP).
•Enhanced Capabilities Port (ECP).
Floppy disk Controller
In the Setup program, the floppy interface can be configured for the following floppy
drive capacities and sizes:
•360 KB, 5.25-inch
•1.2 MBYTES, 5.25-inch
•720 KB, 3.5-inch
•1.44 MBYTES, 3.5-inch
•2.88 MBYTES, 3.5-inch

12
Keyboard and Mouse Interface
PS/2 keyboard and mouse connectors are located on the back panel. The 5 V lines to
these connectors are protected with a PolySwitch†circuit that, like a self-healing fuse,
reestablishes the connection after an over-current condition is removed.
Power to the computer should be turned off before a keyboard or mouse is connected
or disconnected.
The keyboard controller also supports the hot-key sequence <Ctrl><Alt><Del> for a
software reset. This key sequence resets the computer’s software by jumping to the
beginning of the BIOS code and running the Power-On Self Test (POST).
Infrared Support
On the front panel I/O connector (JP2 pins 6-11), there are six pins that support Hewlett
Packard HSDL-1000 compatible infrared (IR) transmitters and receivers. In the Setup
program, Serial Port 2 can be directed to a connected IR device. The connection can
be used to transfer files to or from portable devices like laptops, PDAs, and printers.
The Infrared Data Association (IrDA) specification supports data transfers of up to 115
Kbaud at a distance of 1 meter.
BIOS System Support
BIOS, an acronym for Basic Input Output System, stands as the first link between
hardware and software in coordinating the startup configuration of computers. Plug and
play ready, AMIBlOS automatically configures the computer's hard drives, disk drives,
processors, chipsets, memory, and boot-up of the operating system.
The system BIOS, from AMI, provides ISA PnP and PCI PnP compatibility. The BIOS is
contained in a flash memory device. The BIOS provides the power-on self test (POST),
the system Setup program, a PCI and IDE auto-configuration.
The system BIOS is always shadowed. Shadowing allows any BIOS routines to be
executed from fast 32-bit onboard DRAM instead of from the slower 8-bit flash device.
1. Plug and Play Rev 1.0A support.
2. Boot Block Protection.
3. Auto detects Pipeline Burst SRAM and Cache size, IDE mode type and size.
4. Supports APM 1.2.
5. Supports DMI 2.0.
6. Supports USB.
7. Supports Booting from a Floppy drive, IDE device, CD-ROM, SCSI, Floptical or
Network.
8. 1MBYTES/2MBYTES flash EEPROM for easy BIOS upgrade.

13
PCI IDE
1. “Ultra DMA/33” Synchronous DMA IDE support.
2. Meets Microsoft requirement for PC97.
3. Fully compatible with PCI spec.V2.1.
4. Supports PCI Bus Mastering.
5. Supports Mode 3 and Mode 4 for Enhanced IDE specification.
6. Supports Multi-word DMA mode 0,1,2.
7. Supports PCI burst Read/Write.
8. Supports Primary and Secondary IDE for a total of 4 drives.
9. IDE CD-ROM support.
PCI Auto-configuration
The PCI auto-configuration works in conjunction with the Setup program to support
using PCI add-in boards in the system. When you turn on the system power after
installing a PCI board, the BIOS automatically configures interrupts, DMA channels, I/O
space, and so on. Since PCI add-in boards use the same interrupt resources as ISA
add-in boards, you must specify the interrupts used by non PnP ISA boards in the
Setup program. Chapter 3 tells how to use the Setup program. The PCI auto-
configuration program complies with version 2.1 of the PCI BIOS specification.
IDE Auto-configuration
When an IDE drive is installed in the system, the IDE auto-configuration function
automatically detects and configures the drive for operation in the system. This function
eliminates the need to enter the Setup program after you install an IDE drive.
ISA Plug and Play Capability
This provides auto-configuration of Plug and Play ISA cards and resource management
for legacy (non Plug and Play) ISA cards.
Universal Serial Bus (USB) Support
AMIBIOS 97 stands as the first BIOS to offer full support for the Universal Serial Bus
(USB) standard. The USB technology enables users to quickly and easily attach and
reconfigure a wide range of peripheral devices, from keyboards to printers to telephony
devices. With comprehensive support for both USB host controllers and USB devices,
AMIBIOS 97 offers the ability to fully utilize USB technology now. Support for Intel's
Universal Host Controller Interface (UHCI) ensures compatibility and usability well into
the future. AMI's USB-WARE serves as a total firmware system solution for anyone
using a USB micro-controller.
AMIBIOS 97 offers advanced features for ease-of-use and flexibility: Full Hub Support
Full Bus Enumeration Dynamic Hard Attach/Detach Legacy Keyboard and Mouse
Support.

14
The motherboard features two USB ports as a factory installed option. The ports permit
the direct connection of two USB peripherals without an external hub. If more devices
are required, an external hub can be connected to either of the built-in ports This
motherboard fully supports the standard Universal Host Controller Interface (UHCI) and
uses standard software drivers that are UHCI compatible. Features of the USB include:
•Self-identifying, hot pluggable peripherals.
•Automatic Mapping of function to driver and configuration.
•Support for Isochronous and Asynchronous transfer types over the same set of
wires.
•Support for up to 127 physical devices.
•Guaranteed bandwidth and low latencies appropriate for telephony, audio, and other
applications.
Error handling and fault recovery mechanisms built into protocol.
BIOS Upgrades
Because the BIOS is stored in a flash memory device, you can easily upgrade the BIOS
without having to disassemble the system. The flash upgrade process can be done by
running a utility from a diskette or hard disk, or over a network.
WARNING
For information about the latest BIOS update for the Kootenay, contact your
service representative.
Expansion Slots
This motherboard has two 16-bit ISA slots, four PCI expansion slots and an AGP slot
that supports A.G.P. boards only.
PCI Slots:
Using a 32 bit CPU the PCI bus transfers data at 132 MBytes/second. Part of the
reason for high transfer rates is the PCI bus can operate concurrently with the
processor bus; it doesn’t override it. The CPU can be processing data in an external
cache while the PCI bus is busy transferring information between other parts of the
system. Another key feature of the PCI bus is it’s plug and play capabilities which
eliminates the need for jumper and dip switches for configuring a PCI card.
The PCI slots on the Kootenay motherboard are labeled as:
PCI 1
PCI 2
PCI 3
PCI 4

15
PCI 1 to PCI 4:
These are all fully functional bus-mastering slots.
PCI 3:
This slot shares the PCI Interupt used by the integrated onboard LAN.
PCI 4:
This slot shares the PCI Interupt used by the USB port.
Onboard LAN
The onboard LAN for the Kootenay motherboard is driven by the Intel 82558 chipset.
The Intel82558 is a 10/100 MBps PCI Ethernet LAN Controller. It automatically detects
between 10 Base-T or 100 Base-TX Fast Ethernet connections. This function is a
manufacturing option, if it is not installed the JP1 jumper will also NOT be installed and
the Wake On LAN header WILL be installed.
The LAN LEDs which are mounted next to the LAN connector indicate the following:
Red LED (Speed) On status indicates a 100 MBps connection.
Off status indicates a 10 MBps connection.
Green LED (ACT) Indicates there is activity on the LAN.
Yellow LED (LNK) Indicates if the LAN cable is connected (linked).
Remote reset capabilities are possible from a remote peer or server using the LANDesk
Client Manager, Version 3.11.1 and service layers (when available)
Wake On LAN Header (WOL)
The header, JP3, is used to implement the Wake on LAN feature when the onboard
LAN is not installed. Connect this header to a PCI LAN adapter that supports the Wake
on LAN feature. The adapter monitors network traffic. When the adapter detects a
‘Magic Packet’, it asserts a signal through the Wake on LAN header to wake up the
computer. This signal can wake up the computer only when the AC power cord is still
plugged into the socket and the computer is turned off using the Standby Power button.

16
Front Panel Connector
PWR ON Pins 1 & 2, connected to Standby Switch via twisted pair cable.
SLP Pins 3 & 4, connected to Sleep Switch via twisted pair cable

(white/green respectively).
RST Pins 22 & 23, connected to Reset Switch via twisted pair cable
(orange/white).
SPEAKER Pins 24, 26 & 27, connected to the case speaker via twisted pair cable
(red/black).
Fan Connectors
Three fan connectors are provided, Fan 1 is recommended for the CPU heatsink fan,
Fans 2 & 3 can be used for any other case or heatsink fans.
The pin assignment for these connectors are as follows:
Pin 1 – Ground.
Pin 2 - +12V.
Pin 3 – Sensor
Main Power Connector
The power supply connector is an ATX style twenty-pin male connector. The connector
from the power supply can fit into the socket in only one direction.
Management Extension Hardware
The optional Management Extension component (National Semiconductor LM 78 or
LM79) provides low-cost instrumentation capabilities designed to reduce the total cost
of owning a PC when used with LANDesk Client Manager. The hardware
implementation is a single-chip ASIC. Feature include:
•Integrated temperature monitoring.
•Fan speed monitoring.

17
•Power supply voltage monitoring to detect levels above or below acceptable values.
•Registers for storing POST hardware test results and error codes.
•Chassis Intrusion - This is carried out by the installation of a light sensitive device on
the motherboard (close to the BIOS). This will detect the presence of light if the
chassis cover is removed. Alternatively, a header (close to the BIOS) is installed on
the motherboard for the connection of a micro switch to detect chassis intrusion.
When suggested ratings for temperature, fan speed, or voltage are exceeded, an
interrupt is activated to report the status.
LS-120 Support
LS-120 MBytes Diskette technology enables users to store 120 MBytes of data on a
single, 3.5 Inch removable diskette. LS-120 technology is backward (both read and
write) compatible with 1.44 MBytes and 720 KB DOS-formatted diskettes and is
supported by Windows 95 and Windows NT operating systems.
The Kootenay motherboard allows connection of an LS-120 compatible drive and a
standard 3.5-inch diskette drive. The LS-120 drive can be configured as a boot device,
if selected in the BIOS setup utility.
System Security
The BIOS provides Supervisor level and User level passwords that you can enable
through the Setup program.
Chassis Intrusion Detection is also available as a manufacturing option.

2.Installation and Settings
CAUTION
Electrostatic discharge (ESD) can damage components. Perform the procedures
described in this chapter only at an ESD workstation. If such a station is not
available, you can provide some ESD protection by wearing an antistatic wrist
strap and attaching it to a metal part of the computer.
Jumper Settings
The motherboard contains configuration jumpers that make it possible to change the
system configuration. Normally, the only time you will ever change a jumper is if you
need to:
•Change the system operating speed.
•Change the System mode.
•Power Supply Type.
•Clear Password.
/NOTE
A jumper is a small plastic-encased conductor that slips over jumper pins. To
change a jumper setting, use a pair of fine needle-nosed pliers to remove the
jumper from its current location and slide it onto the new pins to obtain the desired
setting.
CAUTION
Do not squeeze the pliers or other tool you use to remove a jumper, or you might
bend or break the pins.
