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.
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.

Introduction
Chapter 2
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.
Using the SETUP Program

Function
Normal means the parallel port operates in the standard ATcompatible parallel port mode.
The parallel port can be used with devices that adhere to the
Enhanced Parallel Port (EPP) specification. EPP uses the existing parallel port signals to provide asymmetric bi-directional data transfer driven by the host device.
The parallel port can be used with devices that adhere to the
Extended Capabilities Port (ECP) specification. ECP uses the DMA protocol to achieve data transfer rates of 2.5 Mbs. ECP provides symmetric bi-directional communication.
Parallel Port IRQ
This option specifies the IRQ used by the parallel port. It is only available when the
OnBoard Parallel Port option is not set to Auto. The settings are 5 and 7.
Parallel Port DMA Channel
This option sets the DMA channel used by the parallel port. It is only available if the setting for the Parallel Port Mode option is ECP. The settings are 0, 1, and 3.
