CPU SETTINGS

The SY-6VBA133-B provides the user with a very complete and convenient CPU setting environment. The CPU settings are all adjusted through the special SOYO COMBO page in the BIOS, therefore rendering the use of jumpers obsolete. n CPU FSB Frequency The SY-6VBA133-B supports an incredible wide range of CPU FSB frequency settings: 66, 75, 81, 83, 90, 95, 100, 105, 110, 112, 113, 115, 117, 118, 120, 122, 124, 126, 133, 135, 137, 138, 140, 142, 144, 150 and 155 MHz. This ensures that the SY-6VBA133-B has an overwhelming overclocking potential.
n CPU Multiplier The SY-6VBA133-B supports a wide range of multipliers: 2.0x, 2.5x, 3.0x, 3.5x, 4.0x, 4.5x, 5.0x, 5.5x, 6.0x, 6.5x, 7.0x, 7.5x and 8.0x n CPU Core Voltage The CPU Core voltage is set automatically according to CPU needs. The SY-6VBA133-B supports an advanced Core voltage feature; it can be adjusted through the BIOS directly without setting jumper. In normal mode the voltage will be standard, apart from that the user can specify increments of 2.5%, 5%, 7.5% and 10% on top of the standard voltage. This will provide the CPU with the power it needs for overclocking.

2-3.3.4 Back Panel Connections All external devices such as the PS/2 keyboard, PS/2 mouse, printer, modem, USB can be plugged directly onto the Motherboard back panel. Only after you have fixed and locked the Motherboard to the computer case can you start connecting the external peripheral devices. When connecting an external device, use the following figure to locate and identify which back panel connector to plug the device to.
1. Onboard Serial Ports COM1/COM2 External peripherals that use serial transmission scheme include: - serial mouse, - and modem. Plug the serial device cables directly into the COM1/COM2 9-pin male connectors located at the rear panel of the Motherboard. 2. Parallel Port PRT This parallel port is used to connect the printer or other parallel devices. Plug the parallel device cable into the 25-pin female connector located at the rear panel of the Motherboard. 3. PS/2 Keyboard Plug the keyboard jack directly into the 6-pin female PS/2 keyboard connector located at the rear panel of the Motherboard.

Warning: Follow these precautions to preserve your Motherboard from any remnant currents when connecting to ATX power supply: Turn off the power supply and unplug the power cord of the ATX power supply before connecting to ATX PW connector. The Motherboard requires a power supply with at least 200 Watts and a "power good" signal. Make sure the ATX power supply can take at least 720 mA * load on the 5V Standby lead (5VSB) to meet the standard ATX specification. * Note: If you use the Wake-On-LAN (WOL) function, make sure the ATX power supply can support at least 720 mA on the 5V Standby lead (5VSB). Please install the ATX power according to the following pin assignment:
12V 5VSB PW-OK GND 5V GND 5V GND 3.3V 3.3V 5V 5V -5V GND GND GND PS-ON GND -12V 3.3V
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.
Step 3. FSB boot-up frequency and AGP divider: JP2 and JP7
The settings of JP2 and JP7 determine the FSB frequency at boot-up, and more important, they determine the AGP divider and the group of FSB frequencies that can be selected in the BIOS. Refer to the following table:

Short Pin 1-2

Boot-up FSB
BIOS FSB AGP divider group

66~83 1

Short pin 1-2

90~122

Short pin 2-3

124~155

As example, if JP7 is set to open and JP2 to (1-2), the boot-up FSB frequency will be 100MHz. When the BIOS takes control, it will write the BIOS FSB setting to the clock generator. This happens shortly after power-up, and the FSB frequency will then be in accordance to the BIOS setting. The group from which the FSB Frequency can be selected in the BIOS is 90~122MHz and AGP Clock will be 60~81MHz. Note that all FSB Frequencies are available in the BIOS, but that only those in the group as determined by JP2 and JP7 will have effect when selected.
Step 4. CPU B21 and A14 Settings: JP8 and JP9
For certain Intel CPUs, the multiplier is not locked such that setting a multiplier higher than specified on the CPU is possible. For technical details read the following: Your PII /III 100/66 MHz FSB CPU has an input pin B21 (100/66# signal) to tell it what FSB frequency it is running at; The PIII 133 MHz FSB CPU has two pins B21and A14 (133/100# signal). JP8 and JP9 are connected to the B21 and A14 input respectively and are used to tell CPU its FSB speed. The actual FSB Frequency is however set through the BIOS and it may therefore differ from the Frequency specified to the CPU through JP8 & JP9. 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 through JP8 & JP9 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.

Step 1. Select [STANDARD CMOS SETUP]
Set [Date/Time] and [Floppy drive type], then set [Hard Disk Type] to Auto.
Step 2. Select [LOAD SETUP DEFAULT]
Select the LOAD SETUP DEFAULT menu and type Y at the prompt to load the BIOS optimal setup.
Step 3. Select [SOYO COMBO SETUP]
Move the cursor to the [CPU Frequency] field to set the CPU frequency. (1) CPU Name & CPU ID
The BIOS will read the CPU name string and CPU ID code From the CPU and it will display it here. This item provides information only and can not be change.
(2) CPU Frequency Move the cursor to the [CPU Frequency] field to set the CPU frequency. Available [CPU Frequency] settings on your SY-6VBA133-B Motherboard are detailed in the following table.

CPU Frequency (MHz)

750MHz (100 x 7.5) 800MHz (100 x 8.0) 400MHz (133 x 3.0) 466MHz (133 x 3.5) 533MHz (133 x 4.0) 600MHz (133 x 4.5) 666MHz (133 x 5.0) 733MHz (133 x 5.5) 800MHz (133 x 6.0) 866MHz (133 x 6.5) 933MHz (133 x 7.0)
Select the working frequency of your Pentium III, Pentium II, Celeron processor among these preset values. Note: Mark the checkbox that corresponds to the working frequency of your Pentium III, Pentium II, Celeron processor in case the CMOS configuration should be lost.
If you set this field to [Manual], you are then required to fill in the next two consecutive fields: (1) the CPU Host/PCI Clock, and (2) the CPU Ratio. 45
Hardware Installation (1) CPU Host/PCI Clock
CPU Host / PCI Clock o66/33 o95/31 o115/38 o124/41 o140/35 Under this item you find the frequencies your PCI slots run o75/37 o100/33 o117/39 o126/31 o142/35 at. o78/39 o105/35 o118/39 o133/33 o144/36

(2) CPU Ratio After you have selected the CPU Host/ PCI Clock, choose the right multiplier for the CPU. CPU Ratio options are:

ox2 o x 4.5 ox7

o x 2.5 ox5 o x 7.5

ox3 o x 5.5 ox8

o x 3.5 ox6

ox4 o x 6.5

The CPU frequency is then defined as [host clock freq.] x [multiplier], and should equal the working frequency of your CPU. (3) DRAM Clock (3) DRAM Clock Now select the DRAM clock source. It is derived form the CPU FSB clock and it can, depending on the BIOS setting, be: Equal to the CPU FSB clock CPU FSB clock PCI clock CPU FSB clock + PCI clock

As an example: If the user sets the CPU Host/PCI clock to 105/35 MHz, the options will be: Equal to the CPU FSB clock = 105 MHz CPU FSB clock PCI clock = 70 MHz CPU FSB clock + PCI clock = 140 MHz 46
Depending on the DRAM speeds, the user can select one of these speeds through the BIOS. (4) AGP Clock The AGP clock is derived from the CPU FSB frequency. It is divided by 1.0, 1.5 or 2.0 depending on the setting of JP2 and JP7:
Please refer to page 40 for the JP2 and JP7 settings.
(5) 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.

o Normal

o + 2.5 %

o + 5.0 %

o + 7.5%

o +10.0 %

Step 4. Select [SAVE & EXIT SETUP]
Press <Enter> to save the new configuration to the CMOS memory, and continue the boot sequence.
2-3.8 Troubleshooting at First Start
Video (no display) related issues
I built a new computer system using a Soyo board and nothing happens when turning it on, no video and no beeps from the PC speaker. What is happening and how can it be fixed? No screen and no beeps mean that your CPU and motherboard do not work at all. It could be that the CPU is not seated correctly or that a component on the M/B is grounded (shorted) with the case. Also make sure to check the voltage setting switch (110V/220V) on the back of the power supply. To isolate the problem do the following: 1. Press and hold down on the Ins (insert) key while turning on the computer until you get video. If you do not get video then, 2. Double-check jumpers setting on you motherboard and remove all add-on cards, unplug all hard-disk and floppy-disk drive cables and see if you can hear some beeps. If you still do not get any beeps, then try putting the motherboard on the table (to isolate it from the case) with the CPU and speaker only, and give it one more try. I hear a series of beeps and I do not get anything from my monitor. What could be wrong? The following lists some basic beep codes and their possible meanings: One long beep and 3 very short beeps - The video card is not detected by the motherboard. Please re-seat your video card. If you are using an AGP card, please push your AGP card down real hard. You may have to push VERY hard without the AGP card mounting screw. Make sure not to insert the card the other way around. Continuous beeps One or more of the memory modules is not seated correctly in its socket.

Motherboard Description

Chapter 1 MOTHERBOARD DESCRIPTION

1-1 INTRODUCTION

The SY-6VBA 133 AGP/PCI Motherboard is a high-performance Slot 1 supported ATX form-factor system board. SY-6VBA 133 uses the VIA Chipset technology and supports Slot 1 class processors. This Motherboard is fully compatible with industry standards and adds many technical enhancements.

1-2 KEY FEATURES

CPU SUPPORT
The SY-6VBA 133 supports a wide range of INTEL CPUs: n Intel Pentium III 450~600 MHz n Intel Pentium II 233~450 MHz n Intel Celeron 266~433 MHz New released Intel Slot 1 CPUs will very likely be supported by the SY6VBA 133 as well.

CPU SETTINGS

The SY-6VBA 133 provides the user with a very complete and convenient CPU setting environment. The CPU settings are all adjusted through the special SOYO COMBO page in the BIOS, therefore rendering the use of jumpers obsolete. n CPU FSB Frequency The SY-6VBA 133 supports an incredible wide range of CPU FSB frequency settings: 66, 75, 81, 83, 90, 95, 100, 105, 110, 112, 113, 115, 117, 118, 120, 122, 124, 126, 133, 135, 137, 138, 140, 142, 144, 150 and 155 MHz. This ensures that the SY-6VBA 133 has an overwhelming overclocking potential.
n CPU Multiplier The SY-6VBA 133 supports a wide range of multipliers: 2.0x, 2.5x, 3.0x, 3.5x, 4.0x, 4.5x, 5.0x, 5.5x, 6.0x, 6.5x, 7.0x, 7.5x and 8.0x n CPU Core Voltage The CPU Core voltage is set automatically according to CPU needs. The SY-6VBA 133 supports an advanced Core voltage feature; it can be adjusted through the BIOS directly without setting jumper. In normal mode the voltage will be standard, apart from that the user can specify increments of 2.5%, 5%, 7.5% and 10% on top of the standard voltage. This will provide the CPU with the power it needs for overclocking.

HANDLING THE MOTHERBOARD

To avoid damage to your Motherboard, follow these simple rules while unpacking: Before handling the Motherboard, ground yourself by grasping an unpainted portion of the system's metal chassis. Remove the Motherboard from its anti-static packaging. Hold the Motherboard by the edges and avoid touching its components. Check the Motherboard for damage. If any chip appears loose, press carefully to seat it firmly in its socket. Warning: Do not apply power if the Motherboard appears damaged. If there is damage to the board, contact your dealer immediately.

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, 9
two, three, or four sockets. Using the serial presence detect (SPD) data structure, programmed into an EPROM on the DIMM, the BIOS can determine the SDRAMs size and speed. Minimum DIMM memory size is 8 MB; maximum DIMM memory size is 256/512 MB. Memory size and speed can vary between sockets. The motherboard supports the following memory features: l l l l l l 168-pin DIMMs with gold-plated contacts 66/100/133 MHz SDRAM Non-ECC (64-bit) and ECC (72-bit) memory 3.3V memory only Supports 8/16/32/64/128/256/512* MB DIMM Modules (*512MB DIMM1,2 only) Support unbuffered single- or double-sided DIMMs
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.
All memory components and DIMMs used with the SY-6VBA133 motherboard must comply with the PC SDRAM specifications. These include: the PC SDRAM Specification (memory component specific), the PC Unbuffered DIMD Specification, and the PC Serial Presence Detect Specification. 10

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 nonECC 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 Apollo Pro 133 is a high performance, cost-effective and energy efficient chip set for the implementation of AGP/PCI/ISA desktop personal computer systems from 66MHz, 100MHz and 133MHz based on 64-bit Slot 1 super-scalar processors. The Apollo Pro133 chip set consists of the VT82C693A system controller (492 pin BGA) and the VT82C596B PCI to ISA bridge (324 pin BGA). The system controller provides superior performance between the CPU, DRAM, AGP bus, and PCI bus with pipelined, burst, and concurrent operation. The VT82C693A supports eight banks of DRAMs up to 1.5GB. The DRAM controller supports standard Fast Page Mode (FPM) DRAM, EDO-DRAM, Synchronous DRAM (SDRAM) and Virtual Channel SDRAM (VC SDRAM), in a flexible mix / match manner. The Synchronous DRAM interface allows zero wait state bursting between the DRAM and the data buffers at 66/100/133 MHz. The eight banks of DRAM can be composed of an arbitrary mixture of 1M/2M/4M/8M/16M/32MxN DRAMs. The DRAM controller also supports optional ECC (single-bit error correction and multi-bit detection) or EC (error checking) capability separately selectable on a bank-by-bank basis. The DRAM controller can run at either the host CPU bus frequency (66/100/133 MHz) or at the AGP bus frequency (66 MHz) with built-in PLL timing control. 11

The following [HDD Power Down] field may be configured only if [Power Management] is set to [User Define] HDD Power Down Disabled 1-15Min When the set time has elapsed, BIOS sends a command to the HDD to power down. This turns off the HDD motor. Default
Some older model HDDs may not support this advanced function.
The following [Doze Mode] field may be configured only if [Power Management] is set to [User Define] Doze Mode Disable 1Min1Hour Default System clock drops to 33MHz.
When the set time has elapsed, BIOS sends a command to the system to enter Doze Mode.
The following [Suspend Mode] field may be configured only if [Power Management] is set to [User Define] Suspend Mode Disable 1Min1Hour Default In Suspend mode, the CPU stops completely (no instructions are executed.)
Only an SLEnhanced (or SMI) CPU can enter this mode.

SY-6VBA 133 Description When Enabled, your can set the LAN awakens the system. When On of LPT & COM, any activity from one of the listed system peripheral devices or IRQs wakes up the system. When On of HDD & FDD, any activity from one of the listed system peripheral devices wakes up the system. When you are On of DMA/ Master, any activity from one of the list system peripheral devices wakes up the system. Default When set to On, any event occurring at will awaken a system which has been powered down. The following is a list of IRQ s, Interrupt ReQuests, which can be exempted much as the COM ports and LPT ports above can. When an I/O device wants to gain the attention of the operating system, it signals this by causing an IRQ to occur. When the operating system is ready to respond to the request, it interrupts itself and performs the service. When set Off, activity will neither prevent the system from going into a power management mode nor awaken it. 73 Note

SUPERVISOR PASSWORD

Based on the setting you have made in the [Security Option] of the [BIOS FEATURES SETUP] section, the password prevents access to the system or the setup program by unauthorized users. Follow this procedure to set a new password or disable the password: 1. Choose [BIOS FEATURES SETUP] in the Main Menu and press [Enter]. Select the [Security Options] item and set the field to: a. [System]: The password is required every time the system is booted. This means only a person who knows the password can use this computer. b. [Setup]: The password is required only when you attempt to enter the BIOS Setup program. Choose [SUPERVISOR PASSWORD] from the Main Menu and press [Enter]. The following prompt appear: Enter Password: Warning: If you forget or lose the password, the only way to access the system is to set jumper JP5 to clear the CMOS RAM. All setup information is lost and you must run the BIOS setup program again.

Note: If you do not wish to use the password function, press [Enter] directly and the following message appears: Password Disabled!!
