enabling future security and manageability infrastructures for the PC platform. The device
operates under the FWH interface/protocol. The hardware features of this device include a
andom Number Generator (RNG), five General Purpose Inputs (GPIs), register-based
R
block locking, and hardware-based locking. An integrated combination of logic features and
non-volatile memory enables better protection for the storage/update of platform code/data,
adds platform flexibility through additional GPIs and allows for quicker introduction of new

CX6
Introduction of CX6 Features 1-3
scalable Original Equipment Manufacturer (OEM) motherboard riser board and interface,
which supports both audio and modem functions. The specification's main objective is to
reduce the baseline implementation cost of audio and modem functionality. In accordance
with PC user's demands for feature-rich PCs, combined with the industry's current trend
towards lower cost PCs, all of theses functions are built into the motherboard. But
motherboard integration of the modem subsystem has been problematic to date, in large part
due to FCC and other international telecom certification processes that may delay the
introduction of a motherboard. Resolving the homologation/certification issue for modems
is one of the AMR specification's key objectives.
In the future, not only OEM motherboards will have an AMR design, the AMR card will
appear in the market and you can make a choice in buying this kind of card according to your
budget. But your motherboard must have an AMR slot to be able to plug an AMR card. The
CX6 insures this expansibility for this issue.
Yamaha YMF752-S audio chip
YMF752 is an AC’97 Audio CODEC LSI, which is fully compliant with the industry
standard “Audio CODEC ’97” component specification (Revision 2.1).
YMF752 includes a SRC (Sampling Rate Converter) for support variable sampling rate,
which can work the A/D and D/A converter at different rate. YMF752 has an AC-Link serial
interface, which can be used with digital controller LSI. Therefore, YMF752 is the best
audio solution for both laptops and desktop PCs as well as AMR (Audio Modem Riser) and
MDC (Mobile Daughter Card).
YMF752 also supports low power consumption while normal operating and allows for
controlling the power down mode.
Direct Rambus Technology
During the past few years, computer main memory has become the speed bottleneck that has
blocked improved system performance. This is true despite the fact that DRAM densities
have been accelerating sharply from yesterday's 1Kbit per chip to today's 64Mbit devices.
While that aspect of DRAM technology has advanced by a factor of 1,000 in the past 10
years, the time it takes to access main memory has improved by only a factor of five. The
result is that memory bandwidth, the number of bytes per second that can be moved across
memory I/O, has been hobbled. That sluggish performance improvement is now a severe
drag on systems powered by microprocessors that have improved CPU performance 200
fold in the same timeframe.
User’s Manual
1-4 Chapter1
DRAM synchronization has set the stage for system designers to move from a 66MHz to a
100 MHz system bus, partially closing the speed gap between processor and memory. But
even as engineering teams wrestle with this design challenge, microprocessors are
advancing to speeds of 300MHz, 400MHz, and beyond.
Memory technologists are now developing new DRAM architectures that are expected to be
fast enough to unleash the power of tomorrow's processors. These architectures add special
registers to each DRAM pin and special controller functions to the DRAM array core.
Currently, the most fully developed of these architectures is Direct Rambus DRAM (Direct
RDRAM) which uses a special controller, layout, and bus to achieve high I/O bandwidth.
While other firms were employing techniques such as SRAM caches, parallel arrays of
DRAMs, and expensive frame buffers to increase memory bandwidth, Rambus, Inc. took an
entirely different tack. Rambus targeted a two-byte wide data path, 800MHz transfer rate,
and a 95% protocol efficiency. The development resulted in a new chip-to-chip bus, termed
the Direct Rambus Channel (DRC) which includes a controller and one or more Direct
RDRAMs connected together via a common bus. Using a limited number of high-speed
signals to carry all address, data, and control information, DRC links main memory to
system devices that have a need to access memory, including microprocessors, DSPs,
graphics processors, and ASICs. Low voltage swing signaling is used with conventional
PCB technology to permit data transfer up to 800Mbits/s/pin, resulting in the 1.6GB/s peak
bandwidth that will be required for Intel's projected 1999 high-end systems.

STR (Suspend to RAM)
The CX6 supports the STR function. The STR function enables a PC to achieve the S3 state
during idle periods, then quick “wake up” and retrieve the last “state” of the system before it
went to sleep. When idle, STR-enabled systems consume only a small fraction of the power
used for full operation. Instead of shutting down the system to save power when not in use
and then having to reboot later, users can let the STR function take over and not have to
worry about using power to run all the electronics, fans and disks. When needed, a PC with
STR function can restore all applications and features to an operational state within a few
seconds.

Introduction of CX6 Features 1-5
Ultra DMA/66
The CX6 supports Ultra ATA/66 IDE devices. Ultra ATA/66 is the new standard for IDE
devices. It enhances existing Ultra ATA/33 technology by increasing both performance and
data integrity. This new high-speed interface doubles the Ultra ATA/33 burst data transfer
rate to 66.6 Mbytes/sec. The result is maximum disc performance using the current PCI
local bus environment. You can connect either Ultra ATA/33 IDE devices or Ultra ATA/66
IDE devices to the IDE connectors on this motherboard.
PC Health
The CX6 has built-in hardware monitoring functions, that can monitor and protect your
computer insuring a safe computing environment.
Sets You Free From the Y2K Threat
The potential threat of Year 2000 (Y2K) problems are making everyone very nervous. The
Y2K issue applies to almost any device, firmware, or software that operates on or with year
based dates. This problem is caused by a design flaw in the Real Time Clock (RTC) unit.
The RTC only changes the last two digits of the year code, but not the century information.
As a result, when it comes to 12:00 AM January 1, 2000 the RTC will switch from
December 31 11:59 PM 1999 to 12:00 AM January 1 1900.
Y2K compliance deals with the date change over from 31 December 1999 to 1 January 2000,
and with recording and reporting of all dates from the RTC including leap year dates. This
motherboard is free from the Y2K problem because its BIOS are Y2K compliant.
Please Note
If the operating system or application software cannot handle Year 2000 dates, you will
still be facing the Y2K threat because it is not a hardware problem that relates to the
motherboard itself. According to Award BIOS, it is BIOS source code released after 31
May 1995 complies with all known Y2K issues; however, it may still fail the 2000.exe
test. Award has modified its BIOS source code to accommodate the requirements of
2000.exe. Award BIOS source code issued later than 18 November 1996 passes the
NTSL 2000.exe test program.

User Friendly Instructions
Our objective is to enable the novice computer user to perform the installation by himself.
We have attempted to write this document in a very clear, concise and descriptive manner to
help overcome any obstacles you may face during installation. Please read our instructions
carefully and follow them step-by-step.

2-1. Installing the Motherboard to the Chassis
Most computer chassis will have a base on which there will be many mounting holes that
allows the motherboard to be securely attached and at the same time, prevents short circuits.
There are two ways to attach the motherboard to the base of chassis:
with studs
#
or with spacers
#
Please refer to the figure 2-1 that shows the studs and spacers, they may have several types,
but all look like the figures below:
In principle, the best way to attach the
motherboard is with studs, and only if
you are unable to do this should you
attach the board with spacers. Take a
careful look at the motherboard and
you will see many mounting holes on
it. Line these holes up with the
mounting holes on the base. If the
holes line up, and there are screw holes
this means you can attach the motherboard with studs. If the holes line up and there are only
slots, this means you can only attach the motherboard with spacers. Take the tip of the
spacers and insert them into the slots. After doing this to all the slots, you can slide the
motherboard into position aligned with the slots. After the motherboard has been positioned,
check to make sure everything is OK before putting the casing back on.
Figure 2-2 shows you the way to affix the motherboard using studs or spacers:
CX6
Installing the Motherboard 2-3
Note
If the motherboard has mounting holes, but they don’t line up with the holes on the base
and there are no slots to attach the spacers, don’t worry, you can still attach the spacers
to the mounting holes. Just cut the bottom portion of spacers (the spacer may be a little
hard to cut off, so be careful of your hands). In this way you can still attach the
motherboard to the base without worrying about short circuits. Sometimes you may
need to use the plastic springs to isolate the screw from the motherboard PCB surface,
because the circuit wire may be near by the hole. Be careful, don’t let the screw contact
any printed circuit wire or parts on the PCB that are near the fixing hole, otherwise it
may damage the board or cause board malfunctioning.

2-3. Installing System Memory
The memory module for the Camino chipset is different from conventional DIMM. It is
called RIMM (Rambus In-line Memory Module).
The RIMM conforms to the standard DIMM form factor, but it is not pin-compatible. Its
architecture is based on the electrical requirements of the DRC (Direct Rambus Channel)
high-speed bus operating at a clock rate of 400MHz which enables a data rate of 800MHz
because data is clocked on both clock edges. The DRC bus also uses a two byte-wide data
channel, resulting in a peak data transfer rate of 1.6Gbytes per second. The bus uses
transmission line characteristics to maintain high signal integrity.
The CX6 with Camino chipset supports a single Direct Rambus Channel. 300 and 400 MHz
Direct RDRAM devices are supported. 64, 128 and 256 Mbit technology Direct RDRAM
devices are supported. A maximum of 32 Direct RDRAM devices (64Mbit technology =
256 Mbyte Max) are supported for a single channel. The following table shows the
maximum DRAM array size and the minimum increment size for the various DRAM
densities supported for CX6.
Table 2-1 Valid Memory Configurations
RDRAM Technology Increments Maximum
64Mbit 8MB 256MB
128Mbit 16MB 512MB
256Mbit 32MB 1GB
The CX6 provides two 184-pin RIMMs for memory expansion. You have to pay attention to
two things before you want to install RIMMs. Firstly, the serial nature of Direct Rambus
RIMM technology requires that all memory expansion sockets be occupied in order to
complete the transmission line to the termination resistors. For example, a two sockets
configuration where only one Direct Rambus RIMM module is used would require the use
of a continuity module.
Secondly, a single Direct Rambus Channel can connect directly to as many as 32 Direct
RDRAMs placed on a total of two RIMM modules.
How to install RIMMs
Generally, installing Direct RDRAM modules to your motherboard is an easy thing to do.
You can refer to figure 2-3 and 2-4 to see what a 184-pin Direct RDRAM module and
continuity module look like.

2-4. Connectors, Headers and Switches
Inside the case of any computer several cables and plugs have to be connected. These cables
and plugs are usually connected one-by-one to connectors located on the motherboard. You
need to carefully pay attention to any connection orientation the cables may have and, if any,
notice the position of the first pin of the connector. In the explanations that follow, we will
describe the significance of the first pin.
We will show you all connectors, headers and switches here, and tell you how to connect
them. Please pay attention and read the whole section for necessary information before
attempting to finish all of the hardware installation inside the computer chassis.
Figure 2-6 shows you all of the connectors and headers that we’ll discuss in the next section,
you can use this diagram to visually locate each connector and header we describe.
All connectors, headers and switches mentioned here, will depend on your system
configuration. Some features you may (or may not) have and need to connect or configure
depending on the peripheral. If your system doesn't have such add-on cards or switches you
can ignore some special feature connectors.

SMB: System Management Bus Connector
This connector is reserved for system
management bus (SMBus). The SMBus is a
specific implementation of an I
2
C bus. I2C is
a multi-master bus, which means that
multiple chips can be connected to the same
bus and each one can act as a master by
initiating a data transfer. If more than one
master simultaneously tries to control the
bus, an arbitration procedure decides which
master gets priority.
Note: Watch the pin position and the orientation
RT2 head er
The RT2 is for you to connect an additional
thermistor to detect the temperature in the
location of your choice. You can buy the
thermistor at an electronics store, and ask for
a 10KΩ thermistor which should be OK.
Please don’t use too long of a lead wire for
the thermistor.

LED1: Standby LED
This LED is called the Stand-By LED. It
shows if the motherboard is in the power on
state, or is fully powered down. If this LED
light is on, that means your motherboard is
not fully powered down. You can't
disassemble any components, add-on cards,
CPU, or RAM modules in this state. You
have to fully check and shutdown the system
power, before this LED will turn off. Only
then can you disassemble any components, add-on cards, CPU, or RAM module.

connection of two floppy disk drives. After connecting the single end to the FDC1, connect
the two connectors on the other end to the floppy disk drives. In general, people only install
one floppy disk drive on their computer system.
Note
A red mark on a wire typically designates the location of pin 1. You need to align the
wire pin 1 to the FDC1 connector pin 1, then insert the wire connector into the FDC1
connector.
IDE1 and IDE2 Connectors
An IDE hard disk drive ribbon cable has 40
wires and two connectors to provide a
connection for two IDE hard disk drives.
After connecting the single end to the IDE1
(or IDE2), connect the two connectors on
the other end to the IDE hard disk drives (or
CD-ROM drive, LS-120, etc.).
Before you install a hard disk, there are some things you need to be aware of:
“Primary” refers to the first connector on the motherboard, that is, the IDE1 connector on
♦
the motherboard.
“Secondary” refers to the second connector on the motherboard, that is, the IDE2
♦
connector on the motherboard.
Two hard disks can be connected to each connector:
♦
The first HDD is referred to as the “Master”,
The second HDD is referred to as the “Slave”.
For performance issues, we strongly suggest you don’t install a CD-ROM drive on the
♦
same IDE channel as a hard disk. Otherwise, the system performance on this channel may
drop. (how much depends on your CD-ROM drive performance)
