1-7 CHIPSET
To compliment the Intel® Celeron processor, the Intel® 810 chipsets
delivers a balanced platform solution for value computing. The 810
chipset is a highly-integrated three-chip solution consisting of a Graphics
& Memory Controller (Intel 82810), an I/O Controller (Intel82801), and a
Firmware Hub (Intel 82802).
The ICH is a highly integrated multifunctional I/O Controller Hub that
provides the interface to the PCI Bus and integrates many of the functions
needed in today PC platforms. The ICH communicates with the host
controller over a dedicated hub interface. There are two versions of the
ICH (82801AA: ICH and 82801AB: ICH0). These devices are pin
compatible and are in 241-pin packages.
The Intel® 82802 Firmware Hub (FWH) component is part of the Intel®
810 chipset. The FWH is key to enabling future security and
manageabilily infrastructures for the PC platform.
Intel has developed technology that enhances the performance and
exceptional value of the Intel® Celeron™processor-powered PC. Built on
the strong foundation of Intel® 440BX AGPset technology, the Intel® 810
chipset has re-engineered the Value PC, providing next generation features
and great graphics performance at a lower cost.
Richer, more robust 2D and 3D graphics are optimized thanks to an
integrated chipset design that utilizes second-generation graphics
technology. This integrated chipset offers innovative features with
compelling performance while lowering overall system costs.
A new design with big benefits
At the core of the 810 chipset is a memory controller with built-in graphics
technology. The 82810 chip optimizes system memory arbitration, similar

to AGP technology, resulting in a more responsive and cost-effective
system.
The 82810 Graphics Memory Controller Hub (GMCH) features Intel®
graphics technology and software drivers, using Direct AGP (integrated
AGP) to create vivid 2D and 3D effects and images. The 82810 chip
features integrated Hardware Motion Compensation to improve soft DVD
video quality and a digital video out port that enables connection to
traditional TVs or the new space-saving digital flat panel displays.
Intel® Dynamic Video Memory Technology (D.V.M.T.) is an architecture
that offers breakthrough performance for the Value PC segment through
efficient memory utilization and Direct AGP. The system OS uses the Intel
software drivers and intelligent memory arbiter to support richer graphics
applications.
The System Manageability Bus allows networking equipment to monitor
the 810 chipset platform. Using ACPI specifications, the system
manageability function enables low-power sleep mode and conserves
energy when the system is idle.
The 82801 I/O Controller Hub (ICH) employs the Intel® Accelerated Hub
Architecture to make a direct connection from the graphics and memory to
the integrated AC97 controller, the IDE controllers, dual USB ports, and
PCI add-in cards.
The Accelerated Hub Architecture provides twice the bandwidth of the
PCI bus at 266 MB per second. This allows a wider flow of rich
information from the I/O controller to the memory controller, with
optimized arbitration rules allowing more functions to run concurrently,
enabling more life-like audio and video.

The Integrated Audio-Codec 97 controller enables software audio and
modem by using the processor to run sound and modem software. By
reusing existing system resources, this feature adds flexibility, and
improves sound quality.
The 82802 Firmware Hub (FWH) stores system BIOS and video BIOS,
eliminating a redundant nonvolatile memory component. In addition, the
82802 contains a hardware Random Number Generator (RNG). The
Intel® RNG provides truly random numbers to enable fundamental
security building blocks supporting stronger encryption, digital signing,
and security protocols.
Intel 810 chipset re-engineers the Value PC by providing a platform that
will bring next generation features and great graphics performance to
Value PC while reducing overall platform cost.

1-7.1 Accelerated Graphics Port (A.G.P.)
A.G.P. is a high-performance bus for graphics-intensive applications, such
as 3D applications. A.G.P., while based on the PCI Local Bus
Specifications, Rev 2.1, is independent of the PCI bus and is intended for
exclusive use with graphical display devices. A.G.P. overcomes certain
limitations of the PCI bus related to handling a large amount of graphics
data with the following features:
lPipelined memory read and write operations that hide memory access
latency

Motherboard Description SY-7IWA-F
11
lDemultiplexing of address and data on the bus for near 100 percent
bus efficiency
lAC timing for 133 MHz data transfer rates, allowing real data
throughput in excess of 500 MB/sec
1-7.2 Universal Serial Bus (USB)
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 used UHCI-compatible
software drivers.
Specification USB features include:
lSelf-identifying peripherals that can be plugged in while the
computer is running
lAutomatic mapping of function to driver and configuration
lSupport for isochronous and asynchronous transfer types over the
same set of wires
lSupport for up to 127 physical devices
lGuaranteed bandwidth and low latencies appropriate for telephony,
audio, and other applications
lError-handling and fault-recovery mechanisms built into the protocol
¿ Note
Computer systems that have an unshielded cable attached to a USB port
may not meet FCC Class B requirements, even if no device or a low-speed
USB device is attached to the cable. Use shielded cable that meets the
requirements for a full-speed USB device.

Motherboard Description SY-7IWA-F
12
1-7.3 IDE Support
The motherboard has two independent bus-mastering PCI IDE interfaces.
These interfaces support PIO Mode3, PIO Mode 4, ATAPI devices (e.g.,
CD-ROM), and Ultra DMA/33 synchronous-DMA mode transfers. The
BIOS supports logical block addressing (LBA) and extended cylinder head
sector (ECHS) translation modes. The BIOS automatically detects the IDE
device transfer rate and translation mode.
Programmed I/O operations usually require a substantial amount of
processor bandwidth. However, in multitasking operating systems, the
bandwidth freed by bus mastering IDE can be devoted to other tasks while
disk transfers are occurring.
The motherboard also supports laser servo (LS-120) drives. LS-120
technology allows the user to perform read/write operations to LS-120
(120MB) and conventional 1.44MB and 720KB diskettes. An optical
servo system is used to precisely position a dual-gap head to access the
diskett’s 2,490 tracks per inch (tpi) containing up to 120 MB of data
storage. A conventional diskette uses 135 tpi for 1.44 MB of data storage.
LS-120 drivers are ATAPI-compatible and connect to the motherboard’s
IDE interface. (LS-120 drives are also available with SCJSI and parallel
port interfaces.) Some versions of Windows 95 and Windows NT
operating systems recognize the LS-120 drive as a bootable device in both
120 MB and 1.44 MB mode.
Connection of an LS-120 drive and a standard 3.5-inch diskette drive is
allowed. The LS-120 drive can be configured as a boot device if selected
as Drive A in the BIOS setup program.
¿ Note
If you connect at LS-120 drive to an IDE connector and configure it as
the :boot: drive and configure a standard 3.5-inch diskette drive as a “B”
drive, the standard diskette drive is not seen by the operating system.
When the LS-120 drive is configured as the “boot: device, the system will
recognize it as both the A and B drive

Motherboard Description SY-7IWA-F

1-11WAKE ON LAN TECHNOLOGY
Wake on LAN technology enables remote wakeup of the computer
through a network. Wake on LAN technology requires a PCI add-in
network interface card (NIC) with remote wakeup capabilities. The remote
wakeup connector on the NIC must be connected to the onboard Wake on
LAN technology connector. The NIC monitors network traffic at the MII
interface; upon detecting a Magic Packet, the NIC asserts a wakeup signal
that powers up the computer. To access this feature uses the Wake on LAN
technology connector.
* CAUTION
For Wake on LAN, the 5-V standby line for the power supply must be
capable of delivering +5V ±5 % at 720 mA. Failure to provide adequate
standby current when implementing Wake on LAN can damage the power
supply.
