Intel 281809-003 manual Introduction

Introduction

The Advanced/RH motherboard integrates the latest advances in processor, memory, and I/O technologies into a standard LPX form factor that provides leading edge technology. This combination of high integration and high performance makes the Advanced/RH motherboard the ideal platform for the increasing requirements of today's (and tomorrow's) desktop applications in the corporate workspace.

The flexible LPX design will accept Pentium® processors operating at 75 MHz, 90 MHz, 100 MHz, 120 MHz, 133 MHz, 150 MHz and 166 MHz as well as future Pentium processors. The processor subsystem is complemented by a Revision 2.1 Card Edge Low Profile (CELP 2.1) socket that accepts either a 256 KB or 512 KB second level write- back cache module using pipelined synchronous burst technology. There is also an option for having 256 KB of Pipeline Burst SRAM soldered onto the motherboard. If cache memory is soldered on the motherboard, the CELP socket will not be installed. Only one type of cache may be used on the Advanced/RH motherboard. The memory subsystem is designed to support up to 512 MB of EDO DRAM (for improved performance) or standard Fast Page DRAM in standard 72-pin SIMM† sockets. A Type 7 Pentium OverDrive® socket provides an upgrade to future OverDrive processors.

The Advanced/RH motherboard utilizes Intel's 82430HX PCIset to provide increased integration and performance over other motherboard designs. The Intel 82430HX PCIset contains an integrated PCI Bus Mastering IDE controller with two high performance IDE interfaces for up to four IDE devices (such as hard drives, CD-ROM readers, and so forth). The 82430HX PCIset coupled with the integration of the industry’s latest peripherals gives the user a robust computing platform.

Complementing the 82439HX PCI controller is the 82371SB PIIX3 ISA bridge, offering new technology like USB expandability. The PIIX3 performs as a host on the Universal Serial Bus, and in the middle of 1996 Advanced/RH will provide connectors to accommodate USB peripherals.

ATI† 264-VT video, with fast SGRAM video memory, provides excellent performance advantages over alternate solutions using EDO memory. ATI Media Connector modules, supplied by ATI Technologies, can be used to accelerate hardware MPEG and provide the tuner capabilities that previously required an entire add in card. Memory expansion modules, also supplied by ATI, can upgrade the motherboard from 1MB to 2 or 4 MB of SGRAM.

The National PC87306B Super I/O controller integrates the standard PC I/O functions: floppy interface, two FIFO serial ports, one EPP/ECP capable parallel port, a Real Time Clock, keyboard controller, and support for an IrDA† compatible infrared interface.

To provide for the increasing number of multimedia applications, a Creative† VIBRA16S audio CODEC is integrated onto the motherboard. Either consumer audio or business audio is selected by the OEM. Consumer audio will not have onboard jacks, like business audio, but will provide audio connections via an audio riser card. Either audio solution is provided by the VIBRA16S audio controller, and it provides 16-bit stereo, Sound Blaster Pro† compatible audio with full duplex capabilities to meet the demands of interactive multimedia applications. PCI and ISA expansion slots are supported by a connector on the motherboard designed to accept a riser card.

In addition to superior hardware capabilities, a full set of software drivers and utilities are available to allow advanced operating systems such as Microsoft† Windows† 95 to take full advantage of the hardware capabilities. Features such as bus mastering IDE, Windows 95-ready Plug ‘N’ Play, Advanced Power Management (APM) with application restart, software-controlled power supply shutdown, and full duplex audio are all provided by software available for the Advanced/RH.
