1-7 MICROPROCESSOR

The motherboard supports a single Slot 1 processor. The processor’ s VID

pins automatically program the voltage regulator on the motherboard to

the required processor voltage. In addition, the front side bus speed (66

MHz and 100 MHz) is automatically selected. The motherboard supports

all current Slot 1 processor speeds, voltages, and bus frequencies.

1-7.1 Microprocessor Packaging

The processor is packaged in a Single Edge Contact Cartridge (SECC or

SECC2) or Single Edge Processor Package (S.E.P.P). The cartridge

includes the processor core, second-level cache subsystem, thermal plate,

and back cover.

The processor connects to the motherboard through the Slot1 connector, a

242-pin edge connector. When mounted in Slot1, the processor is secured

by a retention mechanism attached to the motherboard. A passive heatsink

is stabilized by the heatsink supports.

1-7.2 Second Level Cache

The second-level cache is located on the substrate of the CPU package.

The cache includes 0KB/128KB (Celeron) or 512 KB (PII/PIII) of

synchronous pipelined burst static RAM. All supported onboard memory

can be cached.

1-7.3 Microprocessor Upgrades

The motherboard can be upgraded with Slot 1 processors that run at higher

speeds. When upgrading the processor, use the BIOS configuration mode

to change the processor speed.

1-8 MEMORY

1-8.1 Main Memory

The motherboard has four DIMM sockets. SDRAM can be installed in one,

Motherboard Description SY-6BA+ IV

two, three, or four sockets. Using the serial presence detect (SPD) data

structure, programmed into an E²PROM on the DIMM, the BIOS can

determine the SDRAM’s size and speed. Minimum DIMM memory size is

8 MB; maximum DIMM memory size is 256MB. Memory size and speed

can vary between sockets.

The motherboard supports the following memory features:

l 168-pin DIMMs with gold-plated contacts

l 66/100/133 MHz SDRAM

l Non-ECC (64-bit) and ECC (72-bit) memory

l 3.3V memory only

l Supports 8/16/32/64/128/256 MB DIMM Modules

l Support unbuffered or registered single- or double-sided DIMMs

Note

Slot 1 processors with 100 MHz front-side bus should be paired only with

100 MHz SDRAM. Processors with 66 MHz front side bus can be paired

with either 66 MHz or 100 MHz SDRAM.

1-8.2 SDRAM

SDRAM improves memory performance through memory access that is

synchronous with the front-side bus clock. Burst transfer rates at x-1-1-1

timing can be achieved using SDRAM, while asynchronous memory

subsystem are typically limited at x-2-2-2 transfer rates.

Note

All memory components and DIMMs used with the SY-6BA+ IV

motherboard must comply with the PC SDRAM specifications. These

include: the PC SDRAM Specification (memory component specific), the

PC Unbuffered DIMM Specification, and the PC Serial Presence Detect

Specification.

Motherboard Description SY-6BA+ IV

1-8.3 ECC Memory

ECC memory detects multiple-bit errors and corrects single-bit errors.

When ECC memory is installed, the BIOS supports both ECC and non-

ECC mode. ECC mode is enabled in the Setup program. The BIOS

automatically detects if ECC memory is installed and provides the Setup

option for selecting ECC mode. If any non-ECC memory is installed, the

Setup option for ECC configuration does not appear and ECC operation is

not available.

1-9 CHIPSET

The Intel 440BX PCIset includes a Host-PCI bridge integrated with both

an optimized DRM controller and an A.G.P. interface. The I/O subsystem

of the 440BX is based on the PIIX4E, which is a highly integrated PCI-

ISA/IDE Accelerator Bridge. This chipset consists of the Intel 82443BX

PCI/A.G.P. controller (PAC) and the Intel 82371EB PCI/ISA IDE

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-6BA+ IV

1-9.5 IDE Support

The motherboard has two independent ATA 33 and two independent ATA

66 bus-mastering PCI IDE interfaces. These interfaces support PIO Mode3,

PIO Mode 4, ATAPI devices (e.g., CD-ROM), and Ultra DMA/33 (IDE1,

IDE2) or Ultra DMA/66 (IDE3, IDE4) synchronous-DMA mode transfers.

See “IDE Device installation” (on page 29) for more information. 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

Motherboard Description SY-6BA+ IV

recognize it as both the A and B drive

1-9.6 Real-Time Clock, CMOS SRAM, and Battery

The real-time clock is compatible with DS1287 and MC146818

components. The clock provides a time-of-day clock and a multicentury

calendar with alarm features and century rollover. The real-time clock

supports 256 bytes of battery-backed CMOS SRAM in two banks that are

reserved for BIOS use.

The time, date, and CMOS values can be specified in the Setup program.

The CMOS values can be returned to their defaults by using the Setup

program.

1-10 I/O INTERFACE CONTROLLER

The motherboard uses the ITE 8671 super I/O controller which features:

l Single diskette drive interface

l ISA Plug-and-Play compatible register set

l Two serial ports

l FIFO supports on both serial and diskette interfaces

l One parallel port with Extended Capabilities Port (ECP) and

Enhanced Parallel Port (EPP) support

l PS/2 style mouse and keyboard interfaces

l PCI PME interface

l Vialigent auto power management, including:

Ø Shadowed write-only registers for ACPI compliance

Ø Programmable wake-up event interface

The Setup program provides configuration option for the I/O controller.

1-10.1 Serial Ports

The NS16C5450-compatible UARTs support data transfers at speeds up to

115.2 Kbits/sec with BIOS support.

1-10.2 Parallel Port

In the Setup program, there are four options for parallel port operation:

l Compatible (standard mode)

Motherboard Description SY-6BA+ IV

l Bi-directional (PS/2 compatible)

l Bi-directional EPP. A driver from the peripheral manufacturer is

required for operation.

l Bi-directional high-speed ECP

1-10.3 Diskette Drive Controller

The I/O controller is software compatible with the 82077 diskette drive

controller and supports both PC-AT and PS/2 modes. In the Setup 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

1-10.4 Keyboard and Mouse Interface

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.

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).

1-10.5 Infrared Support

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

like laptops, PDAs, and printers.

Motherboard Description SY-6BA+ IV

1-11 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.

1-12 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.

ATX Power

This motherboard requires a power supply, that meets the ATX 2.03

specifications. Make sure the power supply can support at least 720mA on

the 5V Standby lead.

Please install the ATX power according to the following pin assignment:

Ø Pay special care to the directionality.

2-3.4 Jumper Setting

Step 1. 5V Stand-by indicator LED (LED 1)

This LED is lit whenever the 5V Standby voltage coming from the ATX

power supply is available. If you have connected your ATX power supply

to the motherboard, LED 1 should be lit.

Step 2. External Suspend Button (JP1)

Some cases come with a suspend button, insert the plug into JP1. In

addition to this button, the system can also enter the suspend mode

through your OS.

Note: Suspend mode only functions if your Power Management mode is APM.

Make sure that the BIOS setting for Power Management is APM. Windows 98

can be installed with ACPI Power Management (default is APM), in this case

suspend mode will not function either.

Hardware Installation SY-6BA+ IV

Step 3. CPU multiplier release Jumper: (JP8)

Closing JP8 can make higher multiplier settings available on some

INTEL CPUs. For technical details read the following:

Your Pentium CPU has an input pin B21 (100/66# signal) to tell it at

what Front Side Bus (FSB) Frequency it is running; JP8 is connected to

this input pin. The actual FSB Frequency is however set through the

BIOS and it may therefore differ from the Frequency specified to the

CPU through JP8.

Because some INTEL CPUs have their multipliers limited at a FSB

Frequency of 100MHz and higher, telling the CPU that it is running at

66MHz though JP8 while setting a different (higher) FSB Frequency in

the BIOS may allow the user to set a higher multiplier value. Doing so

will however force your CPU to operate out of its specifications, and

therefore SOYO can not guarantee the proper functioning of your

system.

Refer to the following table:

Mode JP8

66MHz FSB clock CPUs Setting

66MHz FSB clock CPUs must use

this setting short

100MHz FSB clock CPUs Setting

Normal open

Possible higher multiplier limit short

Note: Shorting the jumper will tell the CPU that it is running on

66MHz, this will release more multiplier settings on some INTEL

CPUs, but will make the system operate out of its specifications if

the actual frequency is 100 MHz or higher.

Hardware Installation SY-6BA+ IV

Step 4. Power-On by Keyboard Jumper (JP10)

You can choose to enable the Power-On by Keyboard function by shorting

pin 1-2 on jumper JP10, otherwise, short pin 2-3 to disable this function.

Note: When using the Power-On by Keyboard function, please

make sure the ATX power supply can take at least 720mA load

on the 5V Standby lead (5VSB) to meet the standard ATX

specification.

2-3.5 CMOS Clearing (JP5)

After you have turned off your computer, clear the CMOS memory by

momentarily shorting pins 2-3 on jumper JP5, for a few seconds. Then

restore JP5 to the initial 1-2 jumper setting in order to recover and retain

the default settings.

Jumper JP5 can be easily identified by its white colored cap.

o83/40 o112/37 o122/37 o137/34 o155/38

o90/30 o113/37 o124/31 o138/34

Under this item you find the

frequencies your PCI and AGP

slots run at. These frequencies

are derived from the CPU host

clock in the following way:

CPU host clock > 100MHz

PCI = CPU host clock /3,

CPU host clock < 100MHz

PCI = CPU host clock /2,

(b) CPU Ratio

After you have selected the CPU Host/ PCI Clock, choose the right

multiplier for the CPU. CPU Ratio options are:

o x 2 o x 2.5 o x 3 o x 3.5 o x 4

o x 4.5 o x 5 o x 5.5 o x 6 o x 6.5

o x 7 o x 7.5 o x 8

The CPU frequency is then defined as [host clock freq.] x [multiplier], and

should the working frequency of your CPUs processor.

Hardware Installation SY-6BA+ IV

This option allows you to manually adjust the AGP host bus clock

frequency to a value determined as a fraction of the CPU host clock.

For example:

With a CPU front side bus of 100MHz,

[Auto] sets

When [auto] is selected and the (FSB Frequency) is

less then 100MHz, it will be divided by [/ 1]. Otherwise it will

be divided by [/ 1.5].

[/ 1] sets

AGP Clock = 100MHz

[/ 1.5] sets àAGP Clock = 66.6MHz

AGP Clock options are:

o Auto o ÷1.0 o÷1.5

(d) Vcore Voltage Adjust

The CPU notifies the board of what core voltage it requires by its VID

outputs. The on-board voltage regulator uses the VID code to set the core

voltage. If the Vcore Voltage Adjust is set to normal, the Vcore will be

exactly what the VID code specifies. If an adjustment percentage is

selected the Vcore will be that percentage higher than the VID code

specifies. For instance the CPU VID code specifies 2.0V and the Vcore

Voltage adjust is set to +10.0% the actual CPU Voltage will be 2.2V. This

function should only be used if the CPU is running on FSB Frequencies

beyond the CPU specifications, note that SOYO does not guarantee

system stability if this item is not set to normal.

Don’t forget to raise the upper limit of the CPU Vcore monitoring voltage

in the Hardware Doctor utility if Vcore is set to higher voltage than VID

specifies.

o Normal o + 2.5 % o + 5.0 % o + 7.5% o +10.0 %

AGP Clock This option allows you to manually adjust the

AGP host bus clock frequency to a value

determined as a fraction of the CPU host clock.

For example:

With a CPU front side bus of 66MHz,

Vcore voltage

Adjust

+10.0%

The CPU notifies the board of what core

voltage it requires by its VID outputs. The

on-board voltage regulator uses the VID

code to set the core voltage. If the Vcore

Voltage adjust is set to normal, the Vcore

will be exactly what the VID code

specifies. If an adjustment percentage is

selected the Vcore will be that percentage

higher than the VID code specifies. If for

instance the VID code specifies 2.0V and

the Vcore Voltage Adjust is set to +10.0%

the actual CPU voltage will be 2.2V. This

function should only be used if the CPU is

running on FSB Frequencies beyond the

CPu specifications.

Driver Installation

Drivers installation SY-6BA+ IV

Your motherboard comes with a hardware monitoring IC. By installing

this utility Temperature, Fan speed and Voltages can be monitored. It is

also possible to set alarms when current system values exceed or fall

below pre-set values.

This utility comes with a preset monitoring rage for the CPU voltage.

However, the core voltage of the processor you purchased may fall out of

this preset range, so you may need to adjust the pre-set value. Please refer to

the SY-6BA+ IV Motherboard’s CD manual for the details.

Select which driver you want to install and click OK, or click Cancel to

abort the driver installation and return to the main menu.

Note: Once you have selected a driver, the system will automatically exit

the SOYO CD to begin the driver installation program. When the

installation is complete, most drivers require to restart your system before

they can become active.

l Core voltage

The core voltage differs between generations of Intel CPUs, if the

Hardware monitor gives a warning, the settings for the safe range of the

core voltage has to be adjusted. This can be done by simply clicking and

dragging the upper and lower limit bars.

For example:

Newer Slot 1 CPUs have a core voltage of 2.0V. Therefore, set the CPU

Vcore limits to 1.8V and 2.2V. For 2.8V core voltage CPUs the limits

would be 2.6V and 3.0V.

l Fan speed

The Hardware monitor can keep track of three fans. If the user does not

use all fans, the fans that are not in use should be disabled in the Hardware

monitor program, otherwise the Hardware monitor will give an alarm. If

this happens, make sure to disable monitoring for that fan.

Note: However, to display the list of all drivers software available with

SOYO Motherboards, click the Display all drivers on the SOYO CD

Click the 'Check the latest Releases' button to go the SOYO Website to

automatically find the latest BIOS, manual and driver releases for your

motherboard. This button will only work if your computer is connected to

the internet through a network or modem connection. Make sure to get

your modem connection up before clicking this button.

Step 5. Select which driver you want to install and click OK

Notice 1: Once you have selected a driver, the system will automatically exit

the SOYO CD to begin the driver installation program. When the

installation is complete, most drivers require to restart your system

before they can become active.

Notice 2: You may click Cancel to abort the driver installation and return to

the main menu.

Notice 3: Once you have selected a driver, the system will automatically exit

and software configuration changes you want to make. Look

specially for conflicts with parts of the existing system configuration

that are not being changed.

If Windows NT can boot but the driver has not been started (see Checking

the Installation), please check the following:

1. Make sure the host adapter is properly installed, and the device is

correctly connected to the adapter. Double check that the cable

between the adapter and the devices is correctly attached. Also check

if the jumper setting on the drive is correct.

2. Make sure that a power cable is properly attached to each drive

attached to the HPT366 host adapter.

If the driver has started and you still cannot access the hard disk drive

attached to the HPT366 host adapter, the hard disk drive might have not

been partitioned and formatted yet. You may need to partition and format

it.
