Chaintech 9VJL3 P4(478)/VIA Motherboard - Answered Questions & Fixed issues

Do not have the Front Panel header pinout.Do have;Take an LED (Light), with two wires, and check the pins with it.There is a Top row of pins, and a Bottom row.Touch the first two pins in the Top row, left side. Does it light up?No? Go to the next two pins. No? Go to the next two pins.Keep going until the Power Supply comes on. (It is a BRIEF touch. The Power On switch is a Momentary Contact Switch )Now you have the Power On switch pins.LED light blinks? You have the Harddrive activity LED. (Light)LED light stays on? You have the Power On LED. (Light)Computer restarts? The Restart switch pins.Short something out? NOPE. You can't hurt a thing using this method.4 of those pins are for an internal speaker. (To hear BIOS Beep Codes with)That's 12 of those 18 pins. (Probably less. It is two rows of 9 pins, that are stated for the Front Panel header)4 of those pins probably won't be used. You won't be using IR. (Infra Remote) (Only uses 2 pins, though)Most of the time with an 18-pin Front Panel header;Top Row:Starting at Left side, going towards Right;Pins 2, 4, 6, 8, 10, 12, 14, 16, and 18.May be a pin missing in this row, or two.Borrom row:Starting at Left side, going towards Right;Pins 1, 3, 5, 7, 9, 11, 13, 15, 17, and 19.Same thing here. May be 1 or 2 pins missing.Pins 2 and 4 are usually for the Power On LED. (Light Emitting Diode)Pins 6 and 8 - Power On switch.Pins 10, 12, 14, and 16 may be for the Internal speaker.Pins 18, and 20 are usually not used.Pin 1 and 3 for the HarDDrive activity LED.Pins 5 and 7 for the Reset switch.Pin 9 is usually reserved for the factory, and is a 5 Volt test point.Pins 11, 13, 15, 17 for speaker; or not used. Same with pin 19.(So speaker pins may be top row, or bottom row. Dunno )Another thing. This motherboard is old enough to be using a 3 wire LED, or dual color; for the Power On LED.LED usually had the colors Green and Yellow.Yellow for 'Normal' mode, Green for 'Turbo' mode.(Which is a bunch of cr@p. Green LED, or Turbo Mode; was actually NORMAL. Normal mode was the computer operating BELOW the Normal mode)So pins 2, 4, and 6, may be for a 3 wire Power On LED.Regards,joecoolvette

Bios is best flashed from a dos (or similar) floppy disk. If you have a floppy then you need to download a boot floppy (I prefer win 98 ones)
and then copy the bin file and the flash utility to that disk.

Bootdisck.com has a selection

Boot from the floppy (you may have to set your bios to do this)

If you don't have a floppy try borrow a usb floppy drive (you may have to tell your bios about it)

If you have windows working there are flash programs that will work from windows.

As with all bios procedures make sure that you have the CORRECT bios for your board. Other bios's will not work and may end up harming your board

Also ALWAYS make a backup of your original bios (best to copy to a flash drive as soon as you can)

You can find a PDF file of the manual for this motherboard here:

http://www.elhvb.com/mobokive/Archive/Chaintech/manuals/6xxxx/6vta2.exe

It includes the jumper functions. The file will download as a self-extracting exe file. I have takent he liberty of insuring it is virus free.

This will take you to Dabs.com and the selection of AGP graphics cards. These will be best price and will work with your system.
Hope this helps.

open your pc ...remove the video card...clean contact surfaces...re-insert the video again and try to boot up again by turning ON the power. Do tis also to your RAM module....hope this works.

heres the chaintech website http://www.motherboard.cz/chaintech.htm you will need to identify your motherboard model - should be written on the actual board and then download the soundcard drivers - you should also download the motherboard chipset drivers, they will have an impact on the performance
you may be able to get the motherboard model by running www.belarc.com
