Component Information
This section is a brief description of the components on the
mainboard that you might need to know about if you want to
upgrade or change your system configuration. If your mainboard
is already installed in a system, it isn’t necessary for you to re-
view this section.
This mainboard uses a Baby-AT ‘form factor’, in a design that
integrates many features onto the board including some number
of external port connectors.
Expansion Cards & Slots
The mainboard has seven expansion slots for system expan-
sion or ‘add-on’ cards. Three of them are ISA slots, three are PCI
slots and one is an AGP (Accelerated Graphics Port) slot. When
you get an expansion card, it must use one of these to connect to
the computer.
The ISA expansion slots are a legacy of the original IBM PC/
AT design. They are16-bitslotsthatrunatamoderatebusspeed.
There are many kinds of expansion cards that use this slot design
to connect to the computer, some of the most common being
sound and modem cards.
PCI slots are the current high-speed 32-bit standard for sys-
tem expansion cards. They operate at a faster speed and have a
greater data throughput than ISA cards.
The AGP Slot is a specialized slot that is only for AGP inter-
face display cards. It provides a high speed interface for the dis-
playcardandisparticularlydesignedtoenhance3Dperformance.
Expansion cards often make use of system resources, which
requiresmanagingthesystemresourceconfiguration.Mostnewer
expansion cards support the ‘Plug and Play’ standard that allows
an Operating System like Windows95 to automatically detect
them and configure system resources as needed. Some older ISA
designs may not support this standard and may therefore require
manual configuration. You should consult the specifications or
documentationforacardtodetermineifthisisthecaseandwhat
needs do be done to properly configure the card.

Memory Sockets & Modules
Therearesix memory module sockets onthemainboard.Two
are for 168-pin DIMM memory modules. The DIMM sockets
function independently of each other. The other four sockets are
for72-pinSIMMmemorymodules.TheSIMMsocketsarepaired
into two ‘banks.’ This means you must install two modules at a
time to fill one bank. You cannot use DIMM and SIMM modules
at the same time on this mainboard.
This mainboard has a very flexible memory design that al-
lows the use of a variety of memory options up to a total of
384MB. There is more information about this in Adding System
Memory section of Section 3: Reconfiguring Your Mainboard.
CPU Socket & CPU
The Socket 7 CPU socket supports the full range of Pentium®-
class CPUs including MMX Pentiums®. Installing a CPU in the
socket is easy. The lever at the side of the socket latches the CPU
in place when it is down and releases it when raised.
If you want to install a CPU upgrade or are installing a CPU
on the board for the first time, please refer to ‘Installing a CPU’ in
Section 3: Reconfiguring Your Mainboard.
Port & Controller Connections
Thereareseveralportsandconnectorsonthemainboard.Some
are external ports and others are internal connectors that connect
to other parts of the computer or internal options.
External Ports
ThismainboardhasseveralexternalportsincludingtheCOM1
and COM2 serial ports, a Parallel port, dual USB ports and PS/2-
typekeyboard and mouse ports. Allbut the keyboard and mouse
ports use external port brackets which mount in expansion card
slot openings and attach to connectors on the mainboard. These
external ports are all accessible at the rear of the computer when
the mainboard is installed.

1: Package & Product Information – 1.8
Internal Connectors
There are also several connectors built onto the mainboard,
includingconnectorsforfourEnhanced IDE devices in two chan-
nels and two floppy disk drives. There are also connectors for a
CPU cooling fan, system chassis cooling fan and a modem ring-
in wake-up cable.
Details about these connectors are in Section 4: Reference In-
formation.

System Controls
There are two topics in this section, a explanation of the hard-
ware controls and status indicators that connect from the main-
board to your system case and some information about the parts
of the CMOS Setup Utility that allow you customize some sys-
tem features.
Hardware Controls & Indicators
Thereare somecontrolfeatures andstatusindicatorsthat con-
nect from the mainboard to your system case, which is some-
times called the ‘Enclosure’ or ‘Chassis.’ These are:
• Power Status Indicator
• Suspend Switch
• Reset Switch
• Hard Disk Drive Activity Indicator
• Keyboard Lock
All of these case features connect to the mainboard via con-
nector J10. Not all system cases have all of these features, so
your system may not have all of them. The functions and op-
tions for these are shown in the table on the next page.

CMOS Setup Utility Controls
Two sections of the CMOS Setup Utility allow you to config-
ure how some of your system’s features work. These are:
• BIOS Features Setup
• Power Management Setup
The CMOS Setup Utility is a program that is permanently
stored in the BIOS chip on the mainboard. The utility creates a
system hardware configuration record that it stores in a small
amount of battery-supported memory on the board. The BIOS
uses this record to function as an interface between the system
hardware and the operating system. Most of the settings in the
CMOS Setup Utility are made automatically, so you won’t nor-
mally need to use this program. You can, however, customize
some of the operational features to suit how you prefer to use
the system.

The CMOS Setup Utility Summary in Section 4: Reference
Information, lists the setting options for each section of the util-
ity including the two noted above.

Therearetwocoolingfanpowerconnectorsonthemainboard.
One is for the CPU cooling fan (CPUFAN1) and the other for a
case-mounted cooling fan (SYSFAN1). When the system enters
Suspend mode, the cooling fans shut off.
UltraDMA Hard Disk Drive Support
This mainboard supports hard disks that use UltraDMA data
transfer. You attach an UltraDMA drive to one of the IDE cables.
If you use the Optimum Settings feature in the CMOS Setup
utility the system will automatically detect the drive and config-
ure the system to use it.
CMOS Support Battery
The disk shaped battery on the mainboard is a 3-volt Lithium
cell battery that supports the small amount of onboard memory
where the CMOS Setup utility’s configuration record is stored.
The battery will last for a number of years and can conceivably
outlast the usage period of the computer it is in.
If the battery fails, the system will not retain the CMOS Setup
configuration and the system will need to be reconfigured every
time you turn it on. If this happens, replace the battery with the
same type as is installed. You can get a replacement at many
electronics supply stores, computer stores and other places that
sell a variety of batteries for various uses.
