NoteNote
NoteNote
Note
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.
NoteNote
NoteNote
Note
The Wake up on LAN header allows the computer to wake from sleep mode, or
power on when a call is received on a network device, such as a LAN.
The first incoming call powers up the computer. A second call must be made to

Power Supply Connector
The power supply converts AC power from a wall outlet to the DC voltages
required by motherboard and devices in your system. The power supply has a
large motherboard connector and several internal device (hard disk, CD-ROM,
and floppy disk drive, etc.) connectors.
The power supply should match the physical configuration of the chassis. Before
attaching all components, make sure the proper voltage has been selected. Power
supplies often can run on a wide range of voltages and must be set (usually via a
switch) to the proper range.

Audio Connectors (Optional)
Your motherboard has three audio jacks (SPK, Line-in, and MIC) and one MIDI/
Game port connector.Your optional audio devices and MIDI/Game device are
connected to these connectors, as shown below.
Figure 11. Connecting the audio devices
Board Expansion Connectors
There are three PCI slots, one ISA slot, and one shared slot (for a PCI or ISA
card). The PCI bus supports up to four bus masters through the four PCI
connectors.
FDD Connector
You can connect your diskette drive(s) to the diskette drive connector on the
motherboard by using the diskette drive ribbon cable. The diskette drive ribbon
cable has two connectors for diskette drives in general. After connecting the one
end of the diskette drive ribbon cable to the motherboard, attach the connector(s)
on the other end to the diskette drive(s).

1-10 Motherboard Description
Primary and Secondary E-IDE Connectors
Your motherboard has two built-in PCI E-IDE interfaces (primary and
secondary). Each interface supports up to two IDE drives (master and slave).
After connecting the one end of the IDE ribbon cable to the primary or secondary
E-IDE connector on the motherboard, connect the connector(s) at the other end
to your IDE drive(s) such as the hard disk drive or CD-ROM drive.
If you install two hard disks by using one IDE ribbon cable, 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 by connecting one
ribbon cable (one hard disk drive will be attached to it) to the primary E-IDE
connector and another ribbon cable (the other hard disk drive will be attached to
it) to the secondary IDE connector. When you install one operating system on an
IDE drive and another on the other IDE drive, you can select the boot device
through the Setup program.
The BIOS in the motherboard supports boot up 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 the 1st/2nd /3rd Boot Device option
to CD-ROM or Floptical in the Advanced Setup menu of the Setup program.
NOTE : The hard disk drive controller on the motherboard supports Ultra DMA/
33, a DMA data transfer protocol for hard disk drives. This allows DMA
commands to transfer data at a maximum burst rate of 33MB/sec. Both the
controller and the hard disk must be capable of supporting Ultra DMA/33 in order
to enable this feature.

About the Setup ProgramAbout the Setup Program
About the Setup ProgramAbout the Setup Program
About the Setup Program
This chapter explains how to use the CMOS Setup program. You can use the
Setup program to change the computer's configuration information and boot-up
sequence, etc.
The Setup program is stored in the computer's read only memory (ROM), so you
can run the program at any time when you turn on or reset your computer. You
need not insert a diskette or access the hard disk.
The Setup program lets you verify or change the followings:
On the Setup menu, you can set up and modify some of the basic options of a
system, such as time, date, diskette drives and hard disk drives.
On the Utilities menu, you can perform system functions.
On the Security menu, you can specify password that can be used to limit
access to the system.
On the Default menu, you can select a group of settings for all CMOS Setup
options.
The configuration you define through the Setup program is stored in a special
area of memory called CMOS RAM. The battery on the main board 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 the Setup program.

2-2 Using the Setup Program
NoteNote
NoteNote
Note
For reference purposes, you should write down the current Setup settings.
When you make changes to the settings, update this record.
You may see a message such as the following:
CMOS Settings Wrong
Press F1 to Resume
If this happens, just press F1 to run the Setup program and then correct the
setting.
Entering the Setup ProgramEntering the Setup Program
Entering the Setup ProgramEntering the Setup Program
Entering the Setup Program
To enter the Setup program, turn the computer on and press <Del> when you see
the message:
"Hit DEL if you want to run SETUP."
As soon as you see this message, hit the DEL key. If you do not press DEL key
quickly, the computer starts loading the operating system and you will not be able
to run the Setup program. If this happens, reset the computer again.
When you enter the Setup program, you will see the Setup menu.

Using the Setup Program
You can use your keyboard or mouse to select the options.
The mouse functions are click (change or select both global and current field) or
double click (perform an operation in the selected field).
The following list provides an overview of function keys in the Setup program.
