Expansion Connectors
Your motherboard contains two 16-bit ISA option slots, three 32-bit PCI option
slots, one PCI/ISA shared slot (CN3 and CN4), and one AGP slot. You can install a
maximum of six option cards, since one PCI and ISA slot share the same chassis I/
O panel.
You can simply install PnP-compliant PCI or ISA option cards without setting
jumpers or switches or performing other configuration tasks by plug and play
capacity. If you turn on the computer after adding PnP-compliant cards, the BIOS
will automatically configure interrupts, I/O space, and other parameters.
See the option card manual that comes with the option card or your system manual
for information on installing or removing option cards.
ISA Expansion Connectors (CN1, CN2, CN3)
You can install ISA option cards to the connectors.
PCI Expansion Connectors (CN4, CN5, CN6, CN7)
You can install PCI option cards to the connectors.
1-6
AGP (Accelerated Graphics Port) Connector (CN8)
Accelerated Graphics Port is a dedicated graphics bus with higher bandwidth, which
allows texturing from main memory. By providing high-bandwidth access to
memory, AGP enables a new level of sophisticated graphics allowing software
developers to create richer, more inviting 3D environments with higher resolutions
than ever before.
Introduction
Diskette Drive Connector (CN20)
You can connect up to two diskette drives to the diskette drive connector. After
connecting the one end of the diskette drive ribbon cable to the motherboard,
connect the two connectors on the other end to the diskette drives.
Figure 1-3. Connecting the Diskette Drive Connector Cable
Enhanced IDE Connectors (CN22 and CN23)
You can connect up to four IDE devices (hard disk drives, CD-ROM drives, and
floptical drives) to the two IDE connectors (primary and secondary).
The PCI Bus Mastering IDE controller supports PIO Mode 3 and 4, and Ultra
DMA/33, a DMA data transfer protocol for IDE devices such as hard disk drives
or CD-ROM drives. The Ultra DMA/33 allows DMA commands to transfer data
at a maximum burst rate of 33 MB/sec. IDE devices must be capable of
supporting Ultra DMA/33 in order to enable this feature. Also, an Ultra DMAaware device driver (a Bus Master IDE driver) for your operating system is
required.
Introduction
1-7
The BIOS in the motherboard supports bootup from IDE CD-ROM drive,
floptical drive, SCSI drive or network drive. So, you can select a CD-ROM drive or
floptical drive as a boot device by setting CD-ROM or Floptical in the Advanced
Setup menu of the SETUP program.
After connecting the one end of the IDE ribbon cable to one of the IDE
connectors on the motherboard, connect the two connectors at the other end to
your hard disk drives.
1-8
Figure 1-4. Connecting the IDE Cable
If you install two hard disks, you must configure the second drive to slave mode by
setting its jumper accordingly. See the manual of your hard disk for the jumper
settings.
You may configure two hard disk drives to be both masters using one ribbon cable
on the primary IDE connector and another ribbon cable on the secondary IDE
connector. You may install one operating system on an IDE drive and another on
the other IDE drive and select the boot device through SETUP.
If you set up your CD-ROM drive as the primary master drive and boot the
system from the CD-ROM drive, the system will recognize the CD-ROM drive as
drive A and your drive A as drive B, and can not recognize your drive B.
Introduction
ATX Primary Power Connector (CN24)
You can connect an ATX-compliant power supply to the 20-pin block ATX power
connector. Connect the cable from the power supply to this connector. Make sure
that the cable from the power supply is aligned with the power connector on the
motherboard and then firmly push down the cable.
When using an ATX-compliant power supply that supports ATX specification 2.1,
connect the auxiliary power cable from the power supply to the 6-pin block auxiliary
power connector next to the ATX primary power connector.

You can connect serial devices such as a mouse, an external modem, or a serial
printer to either serial ports. By default, any device connected to the serial port 1
connector (the serial port 2 connector) is designated in software as COM1
(COM2). You can change these designations through the SETUP program.
Parallel Port Connector (CN11)
You can connect parallel devices such as a printer to the parallel port. By default,
any device connected to this port is designated in software as LPT1. You can set the
I/O address used by this port through the SETUP program.

About the SETUP ProgramAbout the SETUP Program
About the SETUP Program
About the SETUP ProgramAbout the SETUP Program
You can use the SETUP program to change the computer's configuration
information when you installed or removed motherboard options.
The SETUP program is stored in your motherboard's read-only memory (ROM),
so you can run the program any time you turn on or reset the computer. You don't
need to insert a diskette or access a hard disk.
The configuration you define through SETUP is stored in a special area of memory
called CMOS RAM. The battery on the motherboard backs up this memory, so the
memory is not erased when you turn off or reset the computer. Whenever you
reboot the computer, it checks the settings, and if it discovers a difference between
the information in the CMOS RAM and its actual hardware configuration, it
prompts you to run SETUP.

If you do not press Del quickly, the computer starts loading the operating system
and you will not be able to run SETUP. If happens, reset the computer again.
When you enter the SETUP program, you see the System Setup window.
SETUP is composed of four windows that contain several icons. An information

Power Button Function
The option allows holding the power button on the computer to enter suspend
mode as well as functioning as a normal on/off feature of the power button. It
takes effect after finishing power-on self test. The settings are Suspend and On/
Off.
From power-on until power-on self test, you should press the power button for
more than 4 seconds to turn off your system. However, after finishing power-on
self test, the methods for turning off the system depend on the setting for the
option.
When the option is set to Suspend, you should press the power button for more
than 4 seconds to turn off the system after finishing power-on self test. At this
time, if you press the power button for less than 4 seconds, the computer will go
into suspend mode. When the option is set to On/Off, normally pressing the power
button after power-on self test makes the system turned off.
If the Power Management / APM option is set to Disabled, the Power Button
Function option can be used only as a normal On/Off feature.

different access modes: Supervisor mode and User mode.
A Supervisor password and a User password can be set for the SETUP program
and for booting the computer.
Supervisor mode has full access to all the SETUP options whereas User mode has
limited access to the options. Setting separate Supervisor and User passwords
enables a system supervisor to restrict who can change critical SETUP values.
When you run SETUP by entering your User password, you can change the three
items only: Advanced, User, and Color Set.
If you set both the Supervisor and User passwords, you must set the Supervisor
password first. Once both are set, you can enter either the Supervisor password or
the User password to access SETUP or the computer.

are marked with DIMM0 (CN16), DIMM1 (CN15), DIMM2 (CN17) and
DIMM3 (CN18) on your motherboard. You can increase the amount of memory
in your motherboard up to 512 MB by installing DIMMs with a capacity of 8 MB,
16 MB, 32 MB, 64 MB, or 128 MB.
You should use only 3.3V, 168-pin, unbuffered SDRAM (Synchronous DRAM)
DIMMs that operate at an access speed of 60ns or 50ns or faster.
Memory modules must be installed in the DIMM3 socket first.
The motherboard supports ECC (72-bit) or non-ECC (64-bit) DIMMs.

You must install the Microsoft USB Supplement for Windows 95 to configure the
USB ports on the motherboard correctly. If you install the USB Supplement, you
must install it before installing the Bus Master IDE driver for Windows 95.
Follow these steps to install the USB Supplement:
Insert Windows 95 CD into your CD-ROM drive.
1
Click the Start button and then click Run.
2
Type "[CD-ROM drive name]:\OTHER\USB\USBSUPP.EXE" and click OK.
3
When prompted with "Install Microsoft USB Supplement to your system?" click
4
Yes.
At the license agreement screen, review the agreement and then click Yes to
5
continue.
The installation program runs the ScanDisk utility to check the hard disk drive
6
for errors, and then copies the USB Supplement files to the drive. When all files
are copied, the following message is displayed:
Microsoft USB Support Installed! Setup will now restart your system to
complete setup. Please close any applications now.
