I'm having trouble with the pin out connections on a syntax motherboard. Where can i find a diagram?

Why yes I do Joe,

The KT266A is a VIA motherboard chipset,

http://en.wikipedia.org/wiki/List_of_VIA_chipsets#Slot_A_and_Socket_A

The motherboard chipset for your motherboard, consists of a Northbridge, and Southbridge chip.

The Northbridge is a VIA 8366A
The Southbridge is a VIA VT8235

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

[Note*
CPU = Central Processing Unit. Another term used is Microprocessor, or Processor for short ]

The Northbridge chip handles the faster capabilities of a computer.
Handles the Processor, Ram Memory, and HIGH-speed graphics.

[A graphics card installed into a PCI expansion slot is Not high-speed graphics.
Integrated Graphics is Not high-speed graphics.

AGP and PCI Express are high-speed graphics.
If you have an AGP graphics expansion slot, it is handled by the Northbridge chip.
If you have a PCI Express expansion slot, it is handled by the Northbridge chip ]

The Southbridge chip handles the slower capabilities of a computer. This is shown in the diagram.

The VIA KT266A's Northbridge chip, (VT 8366A) supports AMD processors with UP TO a 266MHz Front Side Bus.
(266MHz FSB)

In the chart you see under the FSB heading -> 100 - 133MHz
100MHz to 133Mhz.

AMD processors are 'Double-Pumped'.
Therefore 133MHz becomes 266MHz.

233Mhz with the jumpers at their present positions?

Weird!

Looking at the motherboard, as it is mounted in the computer case; Processor to the Top, Ram Memory slots to the Right,
5 White PCI slots to the Bottom;

The J4 jumper is above the CMOS battery.
The CPU Frequency Select jumper.

(The J1 jumper is right next to the CMOS battery. To the left. That is the Clear CMOS jumper)

The jumper has 3 pins. Number 1 pin is on the LEFT.
From Left to Right; Pins 1, 2, and 3.

With a jumper block,

http://en.wikipedia.org/wiki/File:Jumperblock-shunts.jpg

,on Pins 1 and 2, you have a 100MHz FSB.

With a jumper block on Pins 2 and 3, you have a 133MHz Front Side Bus.

Processor you pick have a broken pin?

You can use AMD Athlon processors with up to a 133Mhz FSB, or AMD Duron processors with up to a 133MHz FSB.

[Actually 200MHz FSB, and 266MHz FSB. Remember what I stated about Double-Pumped ]

Olevia does not seem to make motherboards anymore. I have located a manual that should be it. Try here. this board is a VIA based board made by ECS. Hope it helps.

You wont find one.

The only way you could get one is if the manufacturer of the board would release it to you, and they never do...its proprietary information.

What do you need to know about the board that your looking for a wiring diagram. And just to mention there is no wiring diagram persay.....its a routing diagram, as there are no wires.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

Could be the onboard LAN chipset is going bad. Suggest you buy a cheap Ethernet adapter card, and plug it into one of your available PCI slots. Not to bad mouth, but I have had a lot of trouble with Syntax motherboards.
Here is an example of a cheap Ethernet adapter card, http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3350631&CatId=200

here are some sites that may help you.
all these should be marked power switch may say pw,prs,ps, power led may say pld, pl,led, hhd say hd, reset switch maysay rs, set, these connection will be grouped together, and pin layout 1 red or hot wire, or the main wire for the device you are trying to operate.
www.motherboards.org
www.tomshardware.com
www.twinight.org/chipdir/
www.anandtech.com

the connections to the back plate is standard the amount of pins match up the cable, the number 1 pin will be marked some how and or the cable will only be able to plug in one way.
with an exception if you are using serial connector and we hardly use them. the rules are the same as above, and plug ins maybe one way also.

the ribbon type will have a marking on the cable or ribbin line or dots or hasshs marks that is pin #1
match with pin out on motherboard pin1 or pin 0,

Hi FerretsPgh, according to SiS web site. (Click on this link).
http://www.sis.com/wtb/wtb_prod_46.htm

These motherboards are closely matched to you're board. So the connections may be very similar. You should be able to use the manual for this Asus P4SP-MX motherboard to help you hook items to the motherboard pins.
Here is a picture of the Asus board. (It uses the SiS 651chip).
http://www.asus.com/999/images/products/203/203_l.jpg
To download the manual click on this next link.
http://support.asus.com/download/download.aspx?modelname=P4SP-MX&SLanguage=en-us

If the Asus board doesn't look like you're board than maybe one of these other boards listed in the next link might.
More boards with the SYNTAX S651M chipset.
http://www.dealtime.com/xPP-motherboards--sis651

There is no longer support for the SYNTAX S651M board, (Mainly a manual which is what you realy need). If one looks close, download it's manual.


Good Luck FerretsPgh!

I had this exact problem with a newly bought motherboard and it turned on but the screen was black, also I noticed once it turned on it wouldn't turn off, (Am wondering if this is happening to you) the motherboard was fine as it is in the other room now working away, so dont get rid of it just yet. Most new motherboards require additional power to the processor from the power supply, through a four pin power cable, which should be availble with the newer power supply units having (number of pins for you motherbpard power supply) + 4 (which is the 4 pin J-connector) printed on the packaging. If this is connected and you are still having problems which for me was the case, then you will have to try a different approach. Cutting the chase, the problem I had that produced similar effects of screen being black when the motherboard was powered on, was to do with my case. It was one of those flimsy aluminium foil types. I came to this conclusion by taking my motherboard out of the case and hooking it up to the cases power supply on an insulated surface such as a cork mat. It then worked fine again. So I bought a good qulaity case with a new power supply just to be sure, hooked everything up and hey presto it was fixed. It turned out that enough power couldn't get to the board as the case was shorting its supply. Hope this helps.
