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, 100 MHz and 133 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 (S.E.C.C) 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-6VBA 133

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 256/512 MB. 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 8/16/32/64/128/256/512* MB DIMM Modules

(*512MB DIMM1,2 only)

l Support unbuffered 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-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.

Motherboard Description SY-6VBA 133

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.

Motherboard Description SY-6VBA 133

The VT82C6893A system controller also supports full AGP v1.0 capability for maximum bus utilization including 2x mode transfers, SBA (Side Band Addressing), Flush/Fence commands, and pipelined grants. An eight level request queue plus a four level post-write request queue with thirty-two and sixteen quad words of read and write data FIFO’s respectively are included for deep pipelined and split AGP transactions. A single-level GART TLB with 16 full associative entries and flexible CPU/AGP/PCI remapping control is also provided for operation under protected mode operating environments. Both Window 95 VxD and Windows 98 /NT5.0 mini port drivers are supported for interoperability with major AGP-based 3D and DVD- capable multimedia accelerators. The VT82C693A supports two 32-bit 3.3/5V system buses (one AGP and one PCI) that are synchronous/ pseudo-synchronous to the CPU bus. The chip also contains a built-in bus-to-bus bridge to allow simultaneous concurrent operations on each bus. Five levels (double words) of post write buffers are included to allow for concurrent CPU and PCI operation. For PCI master operation, forty-eight levels (double words) of post write buffers and sixteen levels (double words) of prefetch buffers are included for concurrent PCI bus and DRAM/cache accesses. The chip also supports enhanced PCI bus commands such as Memory-Read-Line, Memory-ReadMultiple and Memory-Write-Invalid commands to minimize snoop overhead. In addition, advanced features are supported such as snoop ahead, snoop filtering, L1 write-back forward to PCI master, and L1 writeback merged with PCI post write buffers to minimize PCI master read latency and DRAM utilization. Delay transaction and read caching mechanisms are also implemented for further improvement of over all system performance. The 324-pinm ball Grid Array VT82C596B PCI to ISA bridge supports four levels (double words) of line buffers, type F DMA transfers and delay transaction to allow efficient PCI bus utilization and (PCI-2.1 compliant) The VT82C596B also includes an integrated keyboard controller with PS/2 mouse support, integrated DS12885 style real time clock with

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 PS/2 Keyboard and Mouse Interface

PS/2 keyboard and mouse connectors are located on the back panel of the motherboard. The +5 V lines to these connectors are protected with a PolySwitch circuit that, like a self-healing fuse, reestablishes the connection after an over-current condition is removed.

Motherboard Description SY-6VBA 133

Note

The mouse and keyboard can be plugged into either PS/2 connector. Power to the computer should be turned off before a keyboard or mouse is connected or disconnected.

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

On the front panel I/O connector, there are six pins that support Hewlett Packard HSDL-1000 compatible infrared (IR) transmitters and receivers. In the Setup program, Serial Port B can be direct4d to a connected IR device. (In this case, the Serial Port B connector on the back panel cannot be used.) The IR connection can be used to transfer files to or from portable devices like laptops, PDAs, and printers. The Infrared Data Association (IrDA) specification supports data transfers of 115Kbits/sec at a distance of 1 meter.

Motherboard Description SY-6VBA 133

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 connector. 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

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).

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:

JP7 JP2

Boot-up

FSB

BIOS FSB

group

AGP divider

Short Short Pin 1-2 66 66~83 1

Open Short pin 1-2 100 90~122 1.5

Open Short pin 2-3 133 124~155 2.0

Hardware Installation SY-6VBA 133

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.

(1) CPU Host/PCI Clock

CPU Host / PCI Clock

o66/33 o95/31 o115/38 o124/41 o140/35 o75/37 o100/33 o117/39 o126/31 o142/35

Under this item you find the frequencies your PCI slots run at.

o78/39 o105/35 o118/39 o133/33 o144/36 o81/40 o110/36 o120/40 o135/33 o150/37 o83/41 o112/37 o122/37 o137/34 o155/38 o90/30 o113/37 o124/31 o138/34

(2) 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 equal the working frequency of your CPU.

(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:

Ø Equal to the CPU FSB clock Ø CPU FSB clock – PCI clock Ø 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:

Ø Equal to the CPU FSB clock = 105 MHz Ø CPU FSB clock – PCI clock = 70 MHz Ø CPU FSB clock + PCI clock = 140 MHz

Hardware Installation SY-6VBA 133

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 %
