Since I have been unable to find a User Manual for a Chaintech 9BJA motherboard, does anyone know where I can find the pin layout for the 9x2 Front Panel Connector to connect the case front panel...
I found the Motherboard Manual for it. It comes as a Zip file.
At first my zip extractor seemed to have problems with it. Unzipped it anyway.
Comes as 8 small files. (Sheesh!)
I'll give you the link to the download website. I'll also tell you how to connect up the Front Panel header, just in case you have problems unzipping the files like I did!
Download website for the Motherboard Manual for the Chaintech 9JBA.
http://www.elhvb.com/mobokive/Archive/Chaintech/manuals/index.html
Scroll down the list on the left. In blue it's -> 9jba0 <- (No, I don't know what the zero is for)
Takes you to another page. Under -> Filename, click on -> 9jba0.exe <- It's 4624KB in size.
(That's about 4.6MB's. Not very big)
It will ask "Do you want to save this file?" Click on Save.
Then the Extraction Wizard will come up. Click on unzip.
If you don't have your downloads going to your My Documents folder, it will pop up these 8 files on your desktop. They're PDF files, and you have Adobe Acrobat Reader on your computer, so it will open these files.
Now, in case you can't download these.
Not to offend, but the manual is a piece of junk. Good thing I've got years of experience with computer motherboards, and reading crappy motherboard manuals.
Hardware setup is in file -> 9bja0-2.pdf (By the way. You can enter the CMOS Setup utility by pressing the Delete key, right after the Chaintech 'splash screen'. { Logo screen)
I am looking at file -> 9bja0-1.pdf now.
I had to expand the PDF file by 800% to see the Front Panel Header. IT IS ->16 pins. 2 x 8
Orient the motherboard, so we're on the 'same page'. Processor is up towards the top, expansion slots, (PCI) are to the left. The Front Panel header is down to the very bottom right corner.
It has -> FTP under it. To the left of it is another header. It has Smark Card under it. (No I didn't misspell it. That's what the mobo manual states) Do Not connect anything to the pins in the Smark Card area.
The Front panel header going lengthwise, there are 7 pins on top, 8 on bottom. Across the top there are 3 pins, NO pin, then 4 more pins.
Pin 1 is on the Bottom all the way to the Left. It doesn't state if it goes Pin 1, 3, 5, 7, 9, 11, 13, and 15,
for the Bottom row of pins, or 1, 2, 3, 4, 5, 6, 7, and 8.
I'm going to number the pins across the Top as Pins, 2, 4, 6, NO Pin, 10, 12, 14, and 16.
Bottom row of pins is Pins 1, 3, 5, 7, 9, 11, 13, and 15.
Top Row
Pins 2, 4, and 6 are for the Power On LED light. The Positive attaches to Pin 2.
There is No Pin 8.
Pins 10 and 12 are for the Green Power switch. Suggest you DON'T connect anything here.
Pins 14 and 16 are for the Override Power Button. Suggest you DON'T connect anything here.
Bottom Row
Pins 1, 3, 5, and 7 are for the internal speaker. Pin 1 is for the Positive connection.
Pins 9 and 11 are for the Power On switch.
Pins 13, and 15 are for the HarDDrive activity light. Pin 13 is for the Positive wire.
More info:
This Chaintech motherboard uses Pentium 4 processors, that use a Socket 478. The processor FSB is 400MHz. (You can't use P4's with a 533MHz FSB, nor ones that use a 800MHz FSB. Go to Wikipedia.org
In Wikipedia's search bar, type -> List of Intel Pentium 4 Microprocessors <-
Look through it, and you'll see P4's that use the Socket 478, and have a 400MHz Front Side Bus)
Has the Intel i845 Northbridge chip, and the ICH2 Southbridge chip. This is the 'motherboard chipset'.
Actual name is Northbridge/Southbridge chipset.
Has 3 ram slots. Maximum TOTAL Amount of ram is 3GB. Maximum Amount for EACH ram slot is 1GB. Uses PC133 ram. (SDR Sdram. Commonly just known as Sdram. ALL ram from Single Data Rate Sdram up to DDR3 Sdram, IS Sdram. That's why just stating just ->Sdram is a misnomer!)
Has to be Low Density ram, and Non-ECC.
The AGP graphics slot is a Universal AGP slot. BUT, it only uses AGP 2X or AGP 4X graphics cards.
They must be able to turn down to 1.5 volts. Using a 3.3 volt AGP graphics card, will result in System Boot up failure, malfunction, etc.
Uses IDE harddrives. (IDE is also referred to as EIDE, ATA, and PATA)
It's an ATX form factor motherboard.
