Question about EPoX EP-8K9A Motherboard

Epox EP-8KHA (VIA KT266) won't wake from suspend

If the system ever goes into suspend mode it won't come back without doing a hard reset. I set power settings in BIOS and Windows to try to not let it go into suspend, but it still does. Maybe can someone assume I didn't know which power settings to adjust and give me a clue for what to set? I'd like to use suspend mode, so that's my first desire, but only if I can wake it up. Otherwise I'd like to not go into suspend so I don't have to do the hard reset. It's dual boot Win98SE and XP (SP2).

    It's a EP-8KHA, not 8K9A.

    Thanks Hanto. Actually I already went down that route, got the newest (and final) BIOS update for the board. The problem remains. It happens whenever the board goes into sleep mode -- whether booted to Windows or not. I could still be in NTLDR waiting to reply, and if I take a break and come back later to find the system in sleep mode I need to re-boot. Or I could already have booted to Windows (either 98SE or XP) and same thing -- if it went into sleep mode I can't wake it up and I need to re-boot. I've fiddled with all the BIOS settings regarding sleep mode (also called green mode). I find this problem with all of those VIA-based boards like KT133,KT133A, KT266/KT266A, KT333, etc.

    Thanks Hanto. I'd appreciate it.

    Thanks Hanto. Yes, I had downloaded the manual and the latest BIOS is installed. I also have the absolute latest 4-in-1 (hiperion) VIA drivers the mobo can stand, and all other Epox/VIA drivers are the most current. It is a clean install of Win98SE with all MS updates 'till the last, and a clean install of WinXP with all updates. All software is legit with no hacks. The board uses the VIA KT266 chipset, is fitted with Athlon XP 1600+ and two 512Mb sticks (slots 1 and 2) and one 256Mb stick (slot 3) of PC2100 memory. Although slot 3 is defective with only 128Mb being recognized. Enumeration shows 256Mb on banks 0,1,2,3,5. I tried several different 256Mb sticks in slot 3 but got the same result and so I have to conclude slot 3 is sort of bad. It runs just fine with the missing 128Mb of memory. There are two 320G IDE drives on an add-in promise ATA 133 controller. The DVD burner is in the on-board primary master. There is an Nvidia MX440 AGP 4x, an add-in USB 2.0, and a Sigma Designs Xcard MPEG decoder. I use a D-link DWL-G120 USB wireless adapter. I've disabled the two serial ports and the parallel port in the BIOS since I don't need them. The thing is, I just found this machine up at the recycling center to be grabbed up and recycled, so I brought it home, cleaned it up, installed D-Link and all the drivers and viola. I can only assume it was junked because someone couldn't live with the memory anonaly. I think the machine was a good bargain despite it being so obsolete. It works very well as long as I don't need to use the restroom for any extended visit or as long as I don't get distracted by some other chore. Even if I have some other task going -- like watchinng a DVD by way of the Xcard -- the machine will go into sleep mode after a while. Only the keyboard or mouse will prevent sleep mode fom being invoked, but even they won't wake it up once it's gone to sleep. And I have read several reports of various other VIA chipsets having the same problem, but have not seen what their solutions were. Thanks for the suggestion of disabling ACPI and going to APM. I haven't tried it, but I will. I'll miss the ACPI's convenience though.

    Hi Hanto. Yes, I do have a PDF of the manual for the board. I can zip it up for you. Where to send it? Now, I believe I found the answer to my problem. I haven't tried it yet, but -- stupid me! -- it is simply in the BIOS wake-up events settings. I left the default of "OFF" for Video. I believe that means the monitor should remain off when the wake-up call comes in from the mouse of keyboard. I will change that to "ON" and watch to see if the problem ever recurrs.

  • two4two Feb 28, 2008

    I never did try to simply turn it off/on. I know, I know....... Also I wasn't sure if you wanted the manual sent to Yahoo, but I'll do that. I thank you for all your thought on this one. I'll definitely let you know when it's solved.

God I hate my keyboard on this Sony laptop. I had written an involved response to your question and lost it due to laptop keyboard interface issues with my thumbs.
Under normal circumstances I would recommend a bios update for your problem but for non technical people that can be a serious and potentially dangerous avenue to success. The fact that you are dual-booting magnifies the potential that problem is possibly not bios related but instead an issue with the two different operating systems on the same motherboard. Which itself might be successfully resolved by a good bios update assuming the manufacturer has written a bios update with that intention. Often bios updates fix issues never mentioned by the manufacturer and are hit or miss with issues they are supposed to fix.
I will say this, Epox has been and I'm sure still is one of the best motherboard manufacturers anywhere in the world and I would be proud to be able to claim one in any system of mine.
The motherboard you mention is very old and you NEED to VERIFY that you have the exact motherboard for the bios update you intend to use. Not doing so will lead to possibly fatal damage to the motherboard, A bad bios update for any reason ( and there are multiple reasons ) will often prove fatal to the M/B.
I would recommend a good deal of research before jumping to any conclusions but here is the website for your manufacturer and the motherboard bios I have mentioned. Please make sure you are dealing with the correct motherboard and bios before attempting anything..

    My memory isn't as good as it used to be but I seem to remember some issues regarding sleep and hibernate modes on those older board also. I personally never allowed use of sleep modes because they, in my experience, could never be trusted to work the same on any two different manufacturers' boards. I would have to say that a perusal of the motherboard manual under bios section would give you as much information as anything I can say. If you can wait a bit, I will try to find that particular manual again and take a quick look at it. Sometimes a jumper configuration ' might ' help but I doubt it would be a complete fix.

    I'm not having much luck with any of the Epox sites tonite, can't seem to load either the Taiwan or the U.S. site very well. Earlier when I finally managed to get on the U.S Epox site, I couldn't download anything from it. Guess I will have to wait.

    If you already happen to have the manual in front of you and since I can't access the Epox sites right now, review your APM settings in the bios and the jumpers that control APM on the motherboard. Keep an open mind i.e. don't let prior opinions about what you ' think ' a jumper setting might do influence you to much. Personally I would consider and usually did run without APM engaged, that might alliviate your issue as I rarely had the problem myself and when I did, I could usually fix it by disengaging APM if my memory serves me correctly, And I hate to say it, but that might be a big ' IF '

    It's hard for me to believe but I think I've been faked out by the good looks of the Epox website. I see that they haven't developed anything new since the end of first quarter 2007. I also saw where they indicated they were moving back in 2007 but nothing indicates they finished with the move of their U.S. branch. I now strongly suspect that Epox is virtually a dead company, with only minimal access to suppport items ( very lucky I think to have that ). I have tried several times using every branch location I can comprehend to access the manual for your motherboard with no success. I can only hope that along with the latest bios you downloaded previously that you also downloaded the manual for the motherboard.

    Ravel Lively Feb 27, 2008

    If you still have the compressed, txt, or pdf version of the manual, send me a copy please. ' '

    Most of the old motherboards suffered some flaws, in general I rarely saw a motherboard that didn't have something wrong with it, and it would depend on how long I had to work with it to find the little issues that others rarely believed. Dead power or hard drive activily leds were quite common, and I've seen the issue you mention of the system not being able to see the memory beyond 640 MBs of memory. I seriously doubt the system was thrown away for that reason. Back in those days that much memory was a gold mine for anyone running heavy programming. People don't realize it much because they don't really examine their systems the way I do ( but it takes lots of time to really work with a system also ). All in all, and especially from what you just indicated to me about what you have loaded on the system, I would say you are doing quite well. Does the motherboard exhibit the sleep behavior if all the extra stuff is removed from it??? The reason I ask that is I wonder if you would have installed all the extras if you had seen the sleep behavior before installations. Anyway send me the manual if at all possible

    If as your last comment indicates, the monitor was remaining off even tho you had disengaged suspend mode, you should have been able to simply turn off and then turn on the monitor and get a normal display. Was that ever the scenerio?

    My email account is listed at least twice in the above responses to you but again for the third time ' '

  • Ravel Lively
    Ravel Lively Feb 28, 2008

    assuming you were disengaging suspend mode properly, keyboard or otherwise, and the monitor was still off, a restart of the monitor should have given you a normal display. This is one problem I can say that I have seen. There was one system in particular that used to do that to me. Been to long ago for me to remember exactly what it was constructed with tho.

I have the 8kha+ motherboard, had to re-install winxp and I've lost the drivers cd for this board. All I want to do is download the drivers, but somehow I can't find the drivers.

Your board has Socket A, VIA KT266 chipset, and AC97 codec. Epox is the manufacturer(?). There web site appears to be down but you can try later.

EPoX EP-9NPA7I displays 'F' and '5' post codes

I would start by clearing the CMOS with the reset jumper pin on your mainboard. Then remove all the PCI cards excluding the video card; disconnect the hard drive as well. Boot the computer without the RAM and see if you still get the "F post code." If not download a copy of Ubuntu Linux and burn it to a CD.

Ubuntu 8.10 Live CD

Reinstall the RAM modules and boot to Ubuntu from the CD and run "System Memory Scan" from the Ubuntu Boot Menu. I'm guessing your RAM over-heated and is permantly damaged.
Only the manufacturer knows what the error codes for your board represent; it'd email them from this support link...

Hello, Is there any way I can get a manual for an EPoX EP-8KHA motherboard? Their website is unresponsive.

He's asking for a manual, not something specific about the board.

Connecting to -5V

You will just have to follow the track from pin 18 on the connector to the next solderable point on the board.
