VT8363
The KT133 chip set consists of the VT8363 system controller (552 pin
BGA) and the VT82C686A PCI to ISA bridge (352 pin BGA). The
system controller provides superior performance between the CPU,
DRAM, AGP bus, and PCI bus with pipelined, burst, and concurrent
operation.
The VT8363 support six banks of DRAMs up to 1.5GB. The DRAM
controller supports standard 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 six banks of
DRAM can be composed of an arbitrary mixture of 1M / 2M / 4M / 8M /
16M / 32MxN DRAMs.
The VT8363 system controller also supports full AGP v2.0 capability for
maximum bus utilization including 1x, 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 / Windows 2000 miniport drivers are supported for
interoperability with major AGP-based 3D and DVD-capable multimedia
accelerators.
The VT8363 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 (doublewords) of post
write buffers are included to allow for concurrent CPU and PCI operation.
For PCI master operation, forty-eight levels (doublewords) of post write

buffers and sixteen levels (doublewords) 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-Read-Multiple and Memory-Write-Invalid commands to
minimize snoop overhead. In addition, advanced features are supported
such as snoop ahead, snoop filtering, L1/L2 write-back forward to PCI
master, and L1/L2 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.

1-11 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.

2-3.1 CPU Installation
Your SY-K7VTA motherboard comes with a CPU retention set kit. The
retention set is used to hold the processor attached to the Socket 462 CPU
connector on the motherboard.
Mark your CPU Frequency: Record the working frequency of
your CPU that should be clearly marked on the CPU cover.
FSB 100MHz (Athlon/Duron)
Athlon
750MHz (100 x 7.5)
950MHz (100 x 9.5)
800MHz (100 x 8.0)
1000MHz (100 x 10.0)
850MHz (100 x 8.5)
700MHz (100 x 7.0)
900MHz (100 x 9.0)
Duron
600MHz (100 x 6.0)
650MHz (100 x 6.5)
Follow these instructions to install your Socket 462 processor correctly.
1. Lift the socket handle up to a vertical position.
2. Align the blunt edge of the CPU with the matching pinhole
distinctive edge on the socket.

3. Seat the processor in the socket completely and without forcing.
4. Then close the socket handle to secure the CPU in place.
Remember to connect the CPU Cooling Fan to the
appropriate power connector on the Motherboard. The fan is
a key component that will ensure system stability. The fan
prevents overheating, therefore prolonging the life of your
CPU.

FOC ( Fan-Off Control )
The newly designed SOYO “FOC” is based on the concept of total
protection for CPU, which is very different from currently seen on the
market. The H/W control function is used to see a passive security system
of monitoring and warning. “FOC”, designed by SOYO, gives emphasis
on the concept of total protection. S/W Simultaneous Signal Follow-ups
techniques and Auto Power Off System are included to prevent all
possible damage caused by the MAL-functioning of the CPU fan. With the
help of “O/S On Time Monitoring And Warning” function, provided by
the H/W monitoring system, the double-protection purpose is achieved.
“FOC” includes the following functions:
(1) Simultaneous Signal Follow Ups: Before the system enters the O/S,
H/W will detect the signals of the CPU fan pins, get their
revolution information and send it to the BIOS.
(2) Auto Power Off System: If the BIOS gets the information of CPU
fan revolution, it goes on working normally. If not, it will
inform the system and have the power supply disconnected
immediately. Thus, the CPU is protected from over heating.
Note: The following must be observed to secure the normal functioning of
“Fan-Off Control”:
1. CPU fan with sensor pins must be used.
2. CPU fans approved by AMD are strongly recommended.
3. The “HOT KEY” function is provided for the CPU fans without
sensor pins, to avoid the power off. Users may press the “Insert”
key to jump over the “Power Off” mode; go to the BIOS and
disable “FOC”. Now system can be booted normally.
4. The power connector of the CPU fan must be connected to the
specified “CPU Fan Connector” on the motherboard to secure the
normal functioning of the system.

SY-K7VTA
We provide the following User-Friendly protection features:
1.Fan-Off Control : The motherboard detects the status of the CPU
fan and protects the CPU by automatically disconnecting the
power supply. The default value of this function is Enable. After
booting up, the user may disable it.
2.CPU Socket Sticker : Users will find a sticker on the CPU socket,
which reminds
them of the correct usage of the K7 CPU.
3. Heat Dissipation Paste: Heat Dissipation Paste is included for all
Socket-A motherboards, to enhance the heat dissipation
capability.
Furthermore, we strongly recommend our users to enable the function of
H/W monitoring in the BIOS. This function, together with the FOC,
provide the total protection to the CPU and allow it to maximize its
performance.

2-3.2 SDRAM Memory Module Installation
Your board comes with two DIMM sockets, providing support for up to
1.5GB of main memory using unbuffered and registered DIMM modules
from 8MB to 512MB. On this motherboard, DRAM speed can be set
independent from the CPU front side bus speed. Depending on the DRAM
clock speed setting in the BIOS setup (Chapter 3), appropriate memory
modules must be used. For 66MHz DRAM speed, use PC66 memory; for
100MHz DRAM speed, use PC100 memory; for 133MHz DRAM speed,
use PC133 memory.

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.

Hardware Installation
SY-K7VTA
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
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).
Modem issues
I get an "I/O Conflict" message when I turn on my system and I can
not get my modem to work
47

Hardware Installation
SY-K7VTA
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
'south bridge' 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 from my sound card is distorted when Windows starts.
What is wrong?
First, if you are using an ISA sound card, please make sure the IRQ
needed for the sound card is set to 'Legacy ISA' in the bios. In other words,
if your ISA sound card takes IRQ5, then set IRQ5 to 'Legacy ISA'. Next,
install the 'south bridge' driver for the motherboard.
The sound and everything else works fine except that the recorder and
microphone do not work. What is wrong?

SY-K7VTA
This is because the recorder and microphone in the Windows are not
enabled. Please go to sound properties and enable them.
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 setup 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. If you are running a Cyrix CPU, make sure the 'linear burst
function' is enabled in the bios.
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
2-3.9 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.
