1-6 CHIPSET

The Intel ® 815E Chipset is a high-flexibility chipset designed to

extend from the basic graphics/multimedia PC platform up to the

mainstream performance desktop platform. The chipset consists of a

Graphics and Memory Controller Hub (Intel® 815E GMCH), an I/O

Controller Hub2 (ICH2) for the I/O subsystem, and a Firmware

Hub(FWH). The Intel® 815E GMCH integrates a system memory

SDRAM controller that supports a 64-bit 100/133 MHz SDRAM

array.

The Intel® 815E GMCH integrates a Display Cache SDRAM

controller that supports a 32-bit 133MHz SDRAM array for

enhanced integrated 2D and 3D graphics performance Multiplexed

with the display cache interface is an AGP controller interface to

enable graphics configuration and upgrade flexibility with the Intel®

815E chipset. The AGP interface and the internal graphics device

are mutually exclusive. When the AGP port is populated with an

AGP graphics card the integrated graphics is disabled and thus the

display cache interface is not needed.

1-6.1 The Intel® 815E Chipset System

The Intel® 815E Chipset uses a hub architecture with the Intel®

815E GMCH as the host bridge hub and the 82801BA I/O Controller

requests on the host bus). Host bus addresses are decoded by the

Intel® 815E GMCH for accesses to system memory, PCI memory

and PCI I/O (via hub interface), PCI configuration space and

Graphics memory. The Intel® 815E GMCH takes advantage of the

pipelined addressing capability of the pipelined addressing

capability of the processor to improve the overall system

performance.

The Intel® 815E GMCH supports the 370-pin socket processor.

*370-pin socket (PGA370). The PGA370 is a zero insertion force

(ZIF) socket that a processor in the FC-PGA package will use to

interface with a system board.

1-6.4 System Memory Interface

The Intel® 815E GMCH integrates a system memory controller that

supports a 64-bit 100/133 MHz SDRAM array. The only DRAM

type supported is industry standard Synchronous DRAM (SDRAM).

The SDRAM controller interface is fully configurable through a set

of control registers.

The Intel® 815E GMCH supports industry standard 64-bit wide

DIMMs with SDRAM devices. The thirteen multiplexed address

lines. SMAA[12:0], along with the two bank select lines, SBS[1:0],

allow the Intel® 815E GMCH to support 2M, 4M, 8M, 16M, and

42M x64 DIMM. Only asymmetric addressing is supported. The

Intel® 815E GMCH has 6 SCS# lines (2 copies of each for electrical

loading), enabling the support of up to six 64-bit rows of SDRAM.

The Intel® 815E GMCH targets SDRAM with CL2 and CL3 and

supports both single and double-sided DIMMs. Additionally, the

Intel® 815E GMCH also provides a 1024 deep refresh queue. The

Intel® 815E GMCH can be configured to keep up to 4 page op[en

within the memory array. Pages can be kept open in any one bank of

memory.

SCKE[4:0] is used in configurations requiring powerdown mode for

the SDRAM.

1-6.5 Multiplexed AGP and Display Cache Interface

The Intel® 815E GMCH multiplexes an AGP interface with a

display cache interface for internal 3D graphics performance

improvement. The Display Cache is used only in the internal

graphics. When an AGP card is installed in the system, the Intel®

815E GMCH internal graphics will be disabled and the AGP

controller will be enabled.

1-6.5.1 AGP Interface

A single AGP connector is supported by the Intel® 815E GMCH

AGP interface. The AGP buffers operate in one of two selectable

modes in one of two selectable modes in order to support the AGP

Universal Connector:

1) 3.3V drive, not 5 volt safe – This mode is compliant to the AGP

1.0 and 2.0 specs.

2) 1.5V drive, not 3.3 volt safe – This mode is compliant with the

AGP 2.0 spec.

The following table shows the AGP Data Rate and the Signaling

Levels supported by the GMCH:

Signaling Level

Data Rate 1.5V 3.3V

1x AGP Yes Yes

2x AGP Yes Yes

4x AGP Yes No

The AGP interface supports 4x AGP signaling. AGP semantic

(PIPE# or SBA[7:0]) cycles to SDRAM are not snooped on the host

bus. AGP FRAME# cycles to SDRAM are snooped on the host bus.

The GMCH supports PIPE# or SBA[7:0] AGP address mechanisms,

but not both simultaneously. Either the PIPE# or the SBA[7:0]

mechanism must be selected during system initialization. High

priority accesses are supported. Only memory writes form the hub

interface to AGP are allowed. No transactions from AGP to the hub

1-6.5.3 Display Cache Interface

The Intel® 815E GMCH support a Display Cache SDRAM

controller with a 32-bit 133 MHz SDRAM array. The DRAM type

supported is industry standard Synchronous DRAM (SDRAM) like

that of the system memory. The local memory SDRAM controller

interface is fully configurable through a set of control registers.

1-6.6 Hub Interface

The hub interface is a private interconnect between the Intel® 815E

GMCH and the ICH2.

1-6.7 Intel® 815E GMCH Integrated Graphics Support

The Intel® 815E GMCH includes a highly integrated graphics

accelerator. Its architecture consists of dedicated multi-media

engines executing in parallel to deliver high performance 3D, 2D

and motion compensation video capabilities. The 3D and 2D engines

are managed by a 3D/2D pipeline preprocessor allowing a sustained

flow of graphics data to be rendered and displayed. The deeply

pipelined 3D accelerator engine provides 3D graphics quality and

performance via per-pixel 3D rendering and parallel data paths

which allow each pipeline stage to simultaneously operate on

different primitives or portions of the same primitive. The Intel®

815E GMCH graphics accelerator engine supports perspective-

correct texture mapping, trilinear and anisotropic Mip-Map filtering,

Gouraud shading, alpha-blending, fogging and Z-buffering. A rich

Motherboard Description SY-7ISA+

12

set of 3D instructions permit these features to be independently

enabled or disabled.

For the Intel® 815E GMCH, a Display Cache (DC) can be used for

the Z-buffer is located in system memory.

The Intel® 815E GMCH integrated graphics accelerator’s 2D

capabilities include BLT and arithmetic STRBLT engines, a

hardware cursor and an extensive set of 2D registers and

instructions. The high performance 64-bit BitBLT engine provides

hardware acceleration for many common Windows operations.

In addition to its 2D/3D capabilities, the Intel® 815E GMCH

integrated graphics accelerator also supports full MPEG-2 motion

compensation for software-assisted DVD video playback.

Motherboard Description SY-7ISA+

13

1-6.8 IDE Support

The motherboard has two independent bus-mastering PCI IDE interfaces.

These interfaces support PIO Mode3, PIO Mode 4, PIO Mode 5 ATAPI

devices (e.g., CD-ROM), and Ultra DMA 33/66/100 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 SCSI 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 a 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

program, the diskette drive interface can be configured for the following

diskette drive capacities and sizes.

l 360 KB, 5.25-inch

l 1.2 MB, 5.25-inch

l 720 KB, 3.5-inch

l 1.2 MB. 3.5-inch (driver required)

l 1.25-1.44 MB, 3.5-inch

l 2.88 MB, 3.5-inch

1-7.4 PS/2 Keyboard and Mouse Interface

PS/2 keyboard and mouse connectors are located on the back panel of the

motherboard. The +5 V lines to keyboard and mouse connectors are

protected with a fuse that prevents motherboard components from being

damaged when an over-current condition occurs.

¿

Note

The mouse and keyboard can be plugged into either PS/2 connector.

Power to the computer should be turned off before a keyboard or mouse is

connected or disconnected.

The keyboard controller contains code, which provides the traditional

keyboard and mouse control functions, and also supports Power On/Reset

password protection. Power On/Reset password can be specified in the

BIOS Setup program.

The keyboard controller also supports the hot-key sequence

<Ctrl><Alt><Del>, software reset. This key sequence resets the

computer’s software by jumping to the beginning of the BIOS code and

running the Power On Self Test (POST).

1-7.5 Infrared Support

The IR connection can be used to transfer files to or from portable devices

like laptops, PDAs, and printers.

1-8 HARDWARE MONITOR

The optional hardware monitor subsystem provides low-cost

instrumentation capabilities. The features of the hardware monitor

subsystem include:

Ø An integrated ambient temperature sensor

Ø Fan speed sensors, which monitor the fan 1 and fan 2 connectors

Ø Power supply voltage monitoring to detect levels above or below

acceptable values

When suggested ratings for temperature, fan speed, or voltage are

exceeded, an interrupt is activated. The hardware monitor component

connects to the SMBus.

1-9 WAKE 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.
