Introduction

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.

Serial Port 1 and 2 Connectors (CN10, CN12)
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.

USB Connectors (CN13)
You can connect peripherals such as scanners, printers and joysticks to the USB
(Universal Serial Bus) connectors. USB includes devices that in the past used serial
ports, parallel ports, the keyboard port, the mouse port, and game ports as well as
new kinds of devices. USB peripherals are hot-swappable enabling plug and play for
your peripherals.
