Motherboard Description
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.
You can connect the power supply cable to the power connector on the
motherboard.

Motherboard Description
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.
Also the motherboard has one Accelerated Graphics Port (A.G.P.) connector.
The Accelerated Graphics Port is a high-performance interconnect for
graphic-intended for exclusive use with graphical-display devices.
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).
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.

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 1
st/2nd/3rd
Boot Device option to
CD-ROM or Floptical in the Advanced Setup menu of the Setup program.
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.

Using the BIOS Setup Program
About the Setup Program
This chapter explains how to use the BIOS 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 BIOS Setup
options.
2-12-1

2-12-1
Using the BIOS Setup Program
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. If this
happens, just press F1 to run the Setup program and then correct the setting.
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.
For reference purposes, you should write down the current Setup settings.
When you make changes to the settings, update this record.
When you enter the Setup program, you will see the Setup menu.

Type : The number for a drive with certain identification parameters.
Cyl : The number of cylinders in the disk drive.
HD : The number of heads.
WP : The size of a sector gets progressively smaller as the track diameter
diminishes. Yet each sector must still hold 512 bytes. Write precompensation
circuitry on the hard disk compensates for the physical difference in sector
size by boosting the write current for sectors on inner tracks. This parameter
is the track number where write precompensation begins.
Sec : The number of sectors per track. MFM drives have 17 sectors per track.
RLL drives have 26 sectors per track. ESDI drives have 34 sectors per track.
SCSI and IDE drives have more sectors per track.
Size (MB) : The formatted capacity of the drive. (Size = Number of heads x
Number of cylinders x Number of sectors per track x 512 bytes per sector.)
User : If you are configuring a drive with drive parameters that do not match
drive types, you can select the User in the Type field. You must then enter the
drive parameters on the screen that appears.
AUTO : If the hard disk drive to be configured is an IDE drive, select the
appropriate drive icon (Pri Master, Pri Slave, Sec Master, or Sec Slave).
Select the IDE Detect icon to automatically detect all drive parameters.
BIOS automatically detects the IDE drive parameters (including ATAPI CDROM drives) and displays them. Click on the OK button to accept these
parameters Or you can set the parameters manually if you are absolutely
certain that you know the correct IDE drive parameters.
