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
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 write­back 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.

processors operating at 75 MHz, 90 MHz, 100 MHz, 120 MHz, 133

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.

The Advanced/RH motherboard is designed to fit into a standard LPX form factor chassis. Figure 2 illustrates the
mechanical form factor for the Advanced/RH. The Advanced/RH LPX form factor does adhere to the standard
LPX guidelines in that the outer dimensions are 13” x 9”. Location of the I/O connectors, riser slot, and mounting
holes are in strict compliance with the LPX specification. However, if business audio is selected by an OEM, a
slight modification to the OEM’s chassis may be necessary to accept the audio jacks on the motherboard.

CPU

The Advanced/RH LPX motherboard is designed to operate with 3.3 volt Pentium processors. The 3.3 volt power
is provided by a patented on-board voltage regulator circuit. An on-board jumper enables use of VRE specified
processors. The voltage regulator provides the required voltage for the processor from the 5 volt output of a
standard power supply. Processors which run internally at 75, 90, 100, 120, 133, 150 and 166 MHz, and have
iCOMP
processors will also be supported.

The Pentium processor maintains full backward compatibility with the 8086, 80286, Intel386 and Intel486
processors. It supports both read and write burst mode bus cycles, and includes separate 8 KB on-chip code and
data write-back caches. Also integrated into the Pentium processor is an advanced numeric coprocessor which
significantly increases the speed of floating point operations, while maintaining backward compatibility with the
Intel486DX math coprocessor and complying to ANSI/IEEE standard 754-1985.

Advanced/RH Technical Product Specification •• Page 8

PROCESSOR UPGRADE

The Advanced/RH motherboard is manufactured with the 321-pin (socket 7) ZIF processor socket. Socket 7
provides a processor upgrade path that includes higher performance Pentium OverDrive processors than can be
supported with socket 5. The motherboard is built to support uniplane CPUs. However, a manufacturing option
allows the socket 7 design to support split voltage planes that can supply different voltages for a processor’s CPU
core and for the I/O core. Installing a split plane CPU into a motherboard configured only for uniplane processor
may cause damage to the CPU.

SECOND LEVEL CACHE

The Intel 82430HX PCIset supports a second level cache that uses high performance Synchronous Pipeline Burst
SRAM. Asynchronous cache is not supported by the 82430HX controller. Pipeline Burst (PB) SRAM provides
performance similar to expensive Synchronous Burst SRAMs for only a slight cost premium over slower
performing asynchronous SRAMs.

As a manufacturing option, the Advanced/RH motherboard without onboard cache can be provided with a Card
Edge Low Profile (CELP) version 2.1 socket that provides flexibility for second level cache options. The CELP
socket can accommodate either a 256 KB or 512 KB cache module and is designed to work with modules that
adhere to the COAST (Cache On A Stick) specification, version 2.1. The cache size is automatically detected and
configured by the system BIOS for optimal performance. For a list of cache module suppliers or a copy of the
COAST specification, contact your local Intel sales office or Intel authorized distributor.

SYSTEM MEMORY

The Advanced/RH motherboard provides six 72-pin SIMM sites for memory expansion. The sockets support 512
KB x 32 (2MB double sided SIMMs only), 1M x 32 (4 MB), 2M x 32 (8 MB), 4M x 32 (16 MB), 8M x 32 (32
MB), 16M x 32 (64MB), and 32M x 32 (128MB) single-sided or double-sided SIMM modules. Minimum memory
size is 8 MB and maximum memory size, using four 32M x 32 SIMM modules, is 512 MB. Memory timing
requires 70 ns fast page devices or, for optimum performance 60 ns EDO DRAM. 36-bit SIMM modules may be
used for parity or ECC generation and checking.

The six sockets are arranged as Bank 0, Bank 1, and Bank 2. Each bank consists of two sockets and provides a
64/72-bit wide data path. Both SIMMs i n a bank must be of the same memory size and type, although each bank
may have different types of memory installed. It is even possible to have 70 ns Fast Page DRAM in one bank and
60 ns EDO DRAM in the other, in which case each bank is independently optimized for maximum performance.
Any combination of the banks may be populated. There are no jumper settings required for the memory size or
type, which is automatically detected by the system BIOS. The Advanced/RH motherboard supports only tin-lead
SIMMs.

When banks 1 and 2 are populated at the same time, memory timing is modified from x333 to x444. This is due to
loading on the address line shared by these two banks. In most applications the L2 cache will mask any
performance degradation that is incurred. In addition, when using EDO Parity memory i n an ECC configuration
memory timing is changed from x222 to x333 to allow the chipset to perform Read Modify Writes.

EDO DRAM

Extended Data Out, or Hyper Page, DRAM is designed to improve the DRAM read performance. EDO
DRAM holds the memory data valid until the next CAS# falling edge, unlike standard fast page mode
DRAM which tri-states the memory data when CAS# negates to precharge for the next cycle. With EDO,
the CAS# precharge overlaps the data valid time, allowing CAS# to negate earlier while still satisfying
the memory data valid window time.

Advanced/RH Technical Product Specification •• Page 9

EXPANSION RISER

An expansion slot riser connector of EISA form factor provides the capability to support either two or three PCI
slots by changing a motherboard jumper to route any extra IRQ and ID selects. A riser board can also support up
to five ISA expansion slots. The PCI bus is compliant with the PCI 2.1 specification.

To ensure that the lowest positioned slot on the riser card can support a full length add-in card the following
conditions must be met.

1) The minimum height requirement for the lowest positioned slot on the CPU side of the riser is 1.2”. Therefore
the CPU heat sink should be no more than 1.2” high once installed on the processor.

2) The minimum height requirement for the lowest positioned slot on the SIMM side of the riser is 1.3”.
Therefore, once SIMM memory is installed they should not be taller than 1.3”.

PERIPHERAL COMPONENT INTERCONNECT (PCI) PCISET

The Intel 82430HX PCIset is made up of two components: The 82439HX controller (TXC) and the 82371SB
PCI ISA IDE Xcellerator (PIIX3) ISA bridge. The PCIset provides the following functions:

• PCI 2.1 Compliant

• Enhanced Fast DMA controller

• Interrupt controller and steering

• Counters/Timers

• SMI interrupt logic and timer with Fast On/Off mode

82439HX TXC

The 439HX controller provides all control signals necessary to drive a second level cache and the DRAM array,
including multiplexed address signals. It also controls system access to memory and generates snoop controls to
maintain cache coherency. The 439HX controller comes in a 324 pin Ball Grid Array package.

82371SB PCI ISA IDE XCELERATOR (PIIX3)

The PIIX3 provides the interface between the PCI and ISA buses and integrates a dual channel fast IDE interface
capable of supporting up to 4 devices. USB host/hub bus is provided by the PIIX 3. The PIIX3 integrates seven
32-bit DMA channels, five 16-bit timer/counters, two eight-channel interrupt controllers, PCI-to-AT interrupt
mapping circuitry, NMI logic, ISA refresh address generation, and PCI/ISA bus arbitration circuitry onto the same
device. The PIIX3 comes in a 208 pin QFP package.

Advanced/RH Technical Product Specification •• Page 10

IDE SUPPORT

The Advanced/RH motherboard provides two independent high performance bus-mastering PCI IDE interfaces
capable of supporting PIO Mode 3 and Mode 4 devices. The system BIOS supports Cylinder Sector Head (CHS),
Logical Block Addressing (LBA) and Extended Cylinder Sector Head (ECHS) translation modes as well as ATAPI
(e.g. CD-ROM) devices on both IDE interfaces. IDE device transfer rate and translation mode capability can be
automatically determined by the system BIOS.

Normally, programmed I/O operations require a substantial amount of CPU bandwidth. In multi-tasking operating
systems like Microsoft Windows 95, the CPU bandwidth freed up by using bus mastering IDE can be used to
complete other tasks while disk transfers are occurring. A driver is required for the IDE interface to operate as a
PCI bus master capable of supporting PIO Mode 4 devices with transfer rates up to 22 MB/sec while minimizing
the system demands upon the processor.

Detailed information on the PCIset is available in the Intel 82430HX PCIset data sheet.

NATIONAL SEMICONDUCTOR PC87306B SUPER I/O CONTROLLER

Control for the integrated serial ports, parallel port, floppy drive, RTC and keyboard controller is incorporated into a single
component, the National Semiconductor PC87306B. This component provides:

• Two NS16C550-compatible UARTs with send/receive 16 byte FIFO

— Support for an IrDA compliant Infra Red interface

• Multi-mode bi-directional parallel port

— Standard mode; IBM
— Enhanced Parallel Port (EPP) with BIOS/Driver support
— High Speed mode; Extended Capabilities Port (ECP) compatible

• Industry standard floppy controller with 16 byte data FIFO (2.88 MB floppy support)

• Integrated Real Time Clock accurate within +/- 13 minutes/yr at 25º C and 5 volts when the system is continuously

powered on

• Integrated 8042 compatible keyboard controller

†

and Centronics† compatible

The PC87306B is normally configured by the BIOS automatically. However configuration of these interfaces is possible via
the CMOS Setup program that can be invoked during boot-up. The serial ports can be enabled as COM1, COM2, IrDA, or
disabled. The parallel port can be configured as normal, extended, EPP/ECP, or disabled. The floppy interface can be
configured for 360 KB or 1.2 MB 5¼” media or for 720 KB, 1.2 MB, 1.44 MB, or 2.88 MB 3½” media. Header pins located
near the back of the board allow cabling to use these interfaces

FLOPPY CONTROLLER

The PC87306B is software compatible with the DP8473 and 82077 floppy disk controllers. The floppy interface
can be configured for 360 KB or 1.2 MB 5¼” media or for 720 KB, 1.2 MB, 1.44 MB, or 2.88 MB 3½” media in
the BIOS setup. By default, the Floppy A interface is configured for 1.44 MB and Floppy B is disabled. Another
setup option prevents the user from being able to write to floppy. Configuring the floppy interface for 1.2 MB 3
½” (3-mode floppy) requires the use of a driver to operate correctly.

KEYBOARD INTERFACE

PS/2 keyboard/mouse connectors are located on the back panel side of the motherboard. The 5V lines to these
connectors are protected with a PolySwitch
connection after an over-current condition is removed. While this device eliminates the possibility of having to
replace a fuse, care should be taken to turn off the system power before installing or removing a keyboard or
mouse. The system BIOS can detect and correct keyboards and mice plugged into the wrong PS/2
connector.

Advanced/RH Technical Product Specification •• Page 11

The integrated 8042 microcontroller contains the AMI Megakey keyboard/mouse controller code which, besides
providing traditional keyboard and mouse control functions, supports Power-On/Reset (POR) password protection.
The POR password can be defined by the user via the Setup program. The keyboard controller also provides for
the following "hot key" sequences:

• <CTRL><ALT><DEL>: System software reset. This sequence performs a software reset of the system by jumping to

the beginning of the BIOS code and running the POST operation.

• <CTRL><ALT><+> and <CTRL><ALT><->: Turbo mode selection. <CTRL><ALT><-> sets the system for de-

turbo mode, emulating an 25 MHz AT, and <CTRL><ALT><+> sets the system for turbo mode. Changing the
Turbo mode may be prohibited by an operating system, or when the CPU is in Protected mode or virtual x86 mode
under DOS.

• <CTRL><ALT><defined in setup>: Power down and coffee-break key sequences take advantage of the SMM

features of the Pentium Processor to greatly reduce the system’s power consumption while maintaining the
responsiveness necessary to service external interrupts.

REAL TIME CLOCK, CMOS RAM AND BATTERY

The integrated Real Time Clock (RTC) is DS1287 and MC146818 compatible and provides a time of day clock
and a 100-year calendar with alarm features. The RTC can be set via the BIOS SETUP program. The RTC also
supports a 242-byte battery-backed CMOS RAM area in two banks. This area is reserved for BIOS use. The
CMOS RAM can be set to specific values or cleared to the system default values using the BIOS SETUP program.
Also, the CMOS RAM values can be cleared to the system defaults by using a configuration jumper on the
motherboard. Table B-1, in Appendix B, lists the configuration jumper settings.

An external coin-cell style battery provides power to the RTC and CMOS memory. The battery has an estimated
lifetime of three years if the system is not plugged into the wall socket. When the system is plugged in, power is
supplied from the LPX power supply’s 5v standby current to extend the life of the battery. See Appendix A for
information regarding replacement batteries.

IRDA (INFRA-RED) SUPPORT

A 5-pin interface on the front panel I/O connector is provided to allow connection to a Hewlett Packard HSDSL­1000 compatible Infra-red (IrDA) transmitter/receiver. Once the module is connected to the front panel I/O
header, serial port 2 can be re-directed to the IrDA module, allowing the user to transfer files to or from portable
devices such as laptops, PDA’s and printers using application software such as LapLink. The IrDA specification
provides for data transfers at 115 Kbps from a distance of 1 meter.

PARALLEL PORT

The Parallel port can be configured in the BIOS setup as output only compatible mode, bi-directional mode, ECP
or EPP modes. The highly flexible parallel port can also be assigned to I/O addresses 278H, 378H, or 3BCH and
IRQ’s 5 or 7. Furthermore, a routable DMA scheme allows Plug ‘N’ Play operating systems such as Windows 95
to route either DMA channel 1 or 3 to the parallel port for ECP mode. EPP BIOS support must be provided by a
device driver or TSR.

GRAPHICS SUBSYSTEM

The ATI-264VT controller is a highly integrated multimedia graphics & video controller for PCI bus systems. The VT
achieves enhanced performance with an all in one design that integrates a video scaler, a color space converter, a true color
palette DAC, and a triple clock synthesizer with ATI’s proven Mach64
register compatible with ATI’s Mach64 accelerator series, and therefore is immediately compatible with a wide range of
software applications and drivers.

As a manufacturing option, the Advanced/RH board is also available with an ATI-264CT video controller and 1 MB of
EDO video DRAM, upgradeable to a total of 2 MB by adding 1 MB of socketed video DRAM.

header to reroute COM2 to a breakout in the chassis or IO panel if the customer so desires.
