    my mb(abit kn8 ultra) does not have onboard video. i took all the memory sticks out and tried them one at a time, here is what happens , no matter if i put one stick or all 4 of them , it beeps one long beep then when i put the video card in and turn it back on with the ram installed i get no beeps at all and no post. one more thing is when all the memory sticks are out and there is no video card installed i get a continues short beep and if im not mistaking that means no ram.

Trying your peripherals one at the time is the way to find your problem, Memory first - one beep is good, If your mb has onboard video use it first. if not check the settings in the BIOS may be a shared memory that is not set right. Make sure your memory is computable ck one stick at the time.

GD8 motherboard


The GD8 mobo spec says that the bopard is only compatible with P4 and Celeron D processors so no you cant swap it! Generally the Athlon 1800+ is a better processor but it depends on the mobo, BIOS, RAM setup etc.

Can't install windows XP on my KN8 ultra


I believe you are using a sata drive not ide, correct? The problem is that vista has built in drivers to support your boards sata/raid controller, winxp does not. to work around this you need to go here -
http://www.abit.com.tw/page/en/download/download_driver_detail.php?pFILE_TYPE=Driver&pMAIN_TYPE=Motherboard&pTITLE_ON_SCREEN=KN8+Ultra&pSOCKET_TYPE=Socket%20939
Abit website. for your board - socket 939. KN8 ultra file called NVRaid Installation disk. click on picture, it will download the zip file. extract the files to an empty folder (create one). Then run RFDgen.exe program. It will create the floppy you will need. I hope you have a floppy drive, if not try a usb one. If it has a problem creating the floppy, copy the files in the folder floppydisk to your floppy. there is a readme.txt file in that folder as well that should help explain which option you should select when you install windows. So... once you have the floppy start your computer up with xp disk in and as the screen turns blue, you will see at the bottom of the screen a message - press F6 to select additional drivers. Do just that, a couple of times to be sure. then it changes to press F2, just sit back and wait. eventually it will come to a screen asking if you want to specify additional drivers. press S and the next screen will show you the drivers it found on the floppy. select the one for your configuration (can be changed in the bios). and then windows will load fine. this is necessary for all new systems with sata/raid installing xp. take care.

One long beep.


  1. Leave the memory slot closest to the processor empty and try booting again. Award bios 1 long beep is memory error as the first 64K of the ram stick closest to th processor is accessed first. since you have tried different ram in different locations, let's rule out the board.
  2. If that doesn't solve anything try a different power supply. Sometimes (Phoenix) gives a long beep when system board or power supply are bad.
  3. Now if nothing else has worked it is probably tour mother board.

Motherboard ABIT KN8


i dont know about the red light, but all main boards these days have a built in protection if the cpu fan quits. check the cpu fan connection, ensure that it and the heat sink are dust free. if still no go. update  your question with exact info..e.g. does absolutely nothing.. how many beeps you hear..how long b 4 it dies.. final note: be careful what you touch.. static can harm more that most think and the oil from touching can retain heat.
