1-9 CHIPSET

Ø VT8633

The Pro266 chipset is a high performance, cost-effective and energy efficient chip set for the implementation of AGP / V-Link / PCI / LPC desktop personal computer systems from 66 MHz, 100 MHz and 133 MHz based on 64-bit Socket-370 and Slot-1 (Intel Pentium-III and Celeron) super-scalar processors.

The Pro266 chip set consists of the VT8633 V-Link DDR Host system controller (552 pin BGA) and the VT8233 highly integrated V-Link Client PCI/LPC controller (376 pin BGA). The Host system controller provides superior performance between the CPU, DRAM, AGP bus, and V-Link interface with pipelined, burst, and concurrent operation. The VT8233 VLink Client controller is a highly integrated PCI / LPC controller. Its internal bus structure is based on 66 MHz PCI bus that provides 2x bandwidth compare to previous generation PCI/ISA bridge chips. The VT8233 integrated Client V-Link controller with 266MB/S bandwidth between Host/Client V-Link interface, provides a V-Link-PCI and VLink-LPC controller. It supports five PCI slots arbitration and decoding for all integrated functions and LPC bus.

The VT8633 supports eight banks of SDR / DDR SDRAMs up to 4 GB. The DRAM controller supports standard Synchronous DRAM (SDRAM), and Virtual Channel SDRAM (VC SDRAM or VCM) SDRAM in a flexible mix / match manner, or it can be configured to support DoubleData-Rated (DDR) SDRAM mode. The SDR/DDR 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 / 32M / 64M xN DRAMs. The DRAM controller also supports optional ECC (single-bit error

Page 16

Motherboard Description SY-7VDA

correction and multi-bit detection) or EC (error checking) capability separately selectable on a bank-by-bank basis. The DRAM controller can run either synchronous or pseudo-synchronous mode with the host CPU bus frequency (66 / 100 / 133 MHz).

The VT8633 Host system controller also supports full AGP v2.0 capability for maximum bus utilization including 2x and 4x mode transfers, SBA (SideBand 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 quadwords 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 Windows-95 VXD and Windows-98 / NT5 miniport drivers are supported for interoperability with major AGP-based 3D and DVD-capable multimedia accelerators.

The VT8633 Host system controller supports two 32-bit 3.3 system buses (one AGP and one V-Link) 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 (doublewords) of post write buffers are included to allow for concurrent CPU and V-Link operation. For V-Link Host operation, forty-eight levels (doublewords) of post write buffers and sixteen levels (doublewords) of prefetch buffers are included for concurrent V-Link bus and DRAM / cache accesses. When combined the V-Link Host/Client controllers, it realizes a complete PCI sub-system and supports enhanced PCI bus commands such as MemoryRead-Line, Memory-Read-Multiple 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 write-back 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 overall system performance.

Motherboard Description SY-7VDA

The 352-pin Ball Grid Array VT8233 Client V-Link PCI / LPC controller supports four levels (doublewords) of line buffers, type F DMA transfers and delay transaction to allow efficient PCI bus utilization and (PCI-2.2 compliant). The VT8233 integrated PCI controller and PCI arbitration for up to five PCI slots. One of the PCI REQ / GNT pair can be configured as high-priority to better support a low latency PCI bus master device. The VT8233 integrated networking MAC controller with standard MII interface to an external PHY for 10 / 100Mb base-T Ethernet or 1 / 10Mb PNA home networking.

The VT8233 also includes an integrated keyboard controller with PS2 mouse support, integrated DS12885 style real time clock with extended 256 byte CMOS RAM, integrated master mode enhanced IDE controller with full scatter / gather capability and extension to UltraDMA-33/66/100 for 33/66/100 MB/sec transfer rate, integrated USB interface with root hubs and six function ports with built-in physical layer transceivers, Distributed DMA support, and OnNow / ACPI compliant advanced configuration and power management interface.

For sophisticated power management, the Pro266 chipset provides independent clock stop control for the CPU / SDRAM, PCI, and AGP buses and Dynamic CKE control for powering down of the SDRAM. A separate suspend-well plane is implemented for the SDRAM control signals for Suspend-to-DRAM operation. Coupled with the VT8233 south bridge chip, a complete power conscious PC main board can be implemented with no external TTLs.

The Pro266 chipset is ideal for high performance, high quality, high energy efficient and high integration desktop and notebook AGP / PCI / LPC computer systems.

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 connector. The NIC monitors network traffic at the Ethernet interface; upon detecting a Magic Packet, the NIC asserts a wakeup signal that powers up the computer. This feature uses the Wake on LAN 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.

2-3.7 Troubleshooting at First Start

USB Issues

Can I use USB port 3_4 and port 5_6 for keyboard resume function?

This M/B has 6 USB ports, but only the 2 at the back panel can be used for USB keyboard resume function.

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.

Page 51

BIOS Setup Utility SY-7VDA

• Continuous beeps – One or more of the memory modules is not

seated correctly in its socket.

My PCI VGA card works fine with my system, but when I put in a new AGP card, it does not give me any video. Is my AGP slot bad?

This is a common problem with AGP video cards. The reason is that your AGP card did not get seated into the AGP slot fully and firmly. Please push your AGP card down into the socket real hard, it should snap twice. You may have to unscrew the AGP card to allow the card to go further down. Do take care not to damage the card by using too much force.

I get distorted video my AGP card right after I save my bios. Why is that?

The cause is likely that your AGP card is not running at the correct bus speed. To fix this, please clear the CMOS via JP5 and if it still does not work, please upgrade your motherboard bios to the latest version.

BIOS Issues

Where can I find the BIOS revision of my mainboard?

It will be displayed on the up-left corner on the screen during boot-up. It will show as your board type followed by the revision number, such as 5EH_2CA1 (meaning revision 2CA1 for the SY-5EH board) or 6BA+ IV_2AA2 which means SY-6BA+ IV motherboard with 2AA2 bios.

Where can I find the latest BIOS of my motherboard?

Please go to the technical support page of one of the SOYO websites (Taiwan: www.soyo.com.tw), and look up your motherboard to find the latest BIOS revision.

Hard disk, floppy drive, CD-ROM etc

When I boot up my new computer I got "floppy boot failure" and the LED on the floppy stays on

Make sure the red wire of floppy ribbon cable goes to Pin1 on the floppy drive side (don't trust the "key lock" or "notch") and use the end-connector of the cable (don't use middle one).

Page 52

BIOS Setup Utility SY-7VDA

Modem issues

I get an "I/O Conflict" message when I turn on my system and I can not get my modem to work

What you need to do is to disable 'COM2' (or UART2 or serial port 2) in the bios under integrated peripheral setup.

I have installed my modem drivers several times and I still cannot get my modem to work. Why?

If you are sure that the modem driver has been installed correctly, then you need to install the south bridge driver from the SOYO CD, this is because Windows does not properly recognize relatively new chipsets.

Audio Issues

I do not get any sound from my sound card. What could be wrong?

Please make sure the speaker is connected to the speaker out port on your sound card.

In Device Manager, I keep getting yellow exclamation signs on my sound port even though I have installed my sound driver several times and I could not get my sound card to work. What is wrong?

It is likely that you did not have the correct driver installed. If you are sure that the correct sound driver has been installed, then please install the 'VIA 4 in 1' driver for the motherboard.

The sound is working in my system, but when I play CD music from the CD-ROM, I do not get any sound. What is wrong?

This is because the 3-wire audio cable from the CD-ROM to the sound card is not connected or it is loose.

The sound and everything else works fine except that the recorder and microphone do not work. What is wrong?

This is because the recorder and microphone in the Windows are not enabled. Please go to sound properties and enable them.

Page 53

BIOS Setup Utility SY-7VDA

Lock up (freeze)

When I boot up my system, everything works fine. It sees my CPU and memory, detects my hard drive, floppy drive and CD-ROM but locks up at "Verify DMI pool data... ", and it won’t go any further. What should I do?

Please clear the CMOS via JP5 then choose 'load optimized default' in the bios and save the bios and exit. Next, unplug all other add-on cards except the video card and floppy drive controller, and see if it can boot from floppy. Then put back the peripherals one by one to identify which one causes the lockup.

I can not get my board to run properly.

Please make sure you have the latest bios and driver from the SOYO web site at: http://www.soyo.com

2-3.8 Power Off

There are two possible ways to turn off the system:

1. Use the Shutdown command in the Start Menu of Windows 95/98

to turn off your computer.

2. Press the mechanical power-button and hold down for over 4

seconds, to shutdown the computer. If you press the power-button for less than 4 seconds, then your system will enter into Suspend Mode.

You are now ready to configure your system with the BIOS setup program. Go to Chapter 3: BIOS SETUP
