    TGL + busmastering question

    Hi, I was wondering if TGL only works with busmastering enabled? I have a conflict between my mobo and my G400MAX so I can't use bm. However, whenever I try and run Q3, I get kicked back to the desktop with a 640x480x16 res. My standard is 1280x1024x16. It's really annoying. I've opened the TGL manager and it recognizes Q3 demo being there, but nothing happens. Am I doing something really wrong or do these two need to be on together to work? Thanks for any help you may have.

    My sys:
    K6-300
    196 megs RAM
    G400MAX
    blah blah blah

    By countless experiments I found out that Matrox OpenGL ICD is completely dependant on
    bus mastering being ON. On the other hand D3D
    games run without crashing on my system ONLY
    when Bus Mastering is OFF. Tried Drakan, Unreal (in D3D), Requiem. Quake2, Heretic2 are OpenGl games, and if I run them with Bus mastering off - they crash with an error message " ... caused an error in ...". With the BM on - they both run for about 15 minutes fine, but then the computer freezes competely. Drakan, when running with BM on -
    freezes right in the options screen, with the corrupted graphics and no responce from keyboard.

    TurboGL on the other hand is not working on my system with or without BM, also I tried ALL the BIOS settings from the FAQ, and drivers 5.30, etc ... No luck at all with TGL ..

    Hope this helps!

      Muad'Dib,

      Disabling bus mastering on any Matrox products is not an acceptable solution, as it seriously impairs the hardware expected performance and features.

      I would suggest that you try to solve the bus mastering conflict of G400MAX rather than disable it. If you want people from the forum to help you, *** PLEASE **** include detailed system information and IRQ resource assignment. Most modern motherboards designs should not have bus mastering problem with Matrox products, unless the board itself may be defective.

      My Millenium G400 DH 32MB is working flawlessly on my system. And, the recent release of TurboGL with support for AMD K6-2 is simply kick-ass for OpenGL games!!!

        kjliew - I'm aware that turning off bm is not a solution. In fact, I'm more than aware because I've seen it running with it on and it's simply amazing (coming from a productiva g100 that is ). I've included my detailed system specs. many times while trying to get some help with it. I've done everything that was suggested (except clean install of windows which I will do this week)and still to no avail. I'm not too worried though because I'm getting a new system soon anyway.... Athlon's here I come!!!

        Somewhat more detailed specs (I'm not using my computer so no IRQ list):

        IWILL XA100 mobo
        K6-300
        196 megs PC100 RAM (I think it's pc100)
        G400MAX
        6 gig hd (primary)
        20 gig hd (secondary) - 7200 UDMA 66
        10/100 NIC
        32X CD-ROM
        DVD ROM
        REALMagic Hollywood Plus Decoder
        old sound card which I know conflicts with the G400...

        Ummm, should this be moved to hardware now Kruzin???

          Muad'Dib,

          You still miss out two very critical information to analyze your problem. The OS and the chipsets used in the motherboard. For the latter, I have looked out myself, but don't expect me or anyone will do this everytime.

          There are very important drivers which you must install ensure smooth operation of any AGP cards in SS7 system. They are IDE bus mastering driver, AGP GART driver and IRQ routing driver. Depends on the OS used, you may skip one or two of them because Microsoft has incorporated full supports of the respective chipsets in the built-in drivers. Check ALi website for further information.

          Win95 OSR2.1
          Install all three.

          Win98
          BMIDE (check)
          IRQ Router (check)
          AGP (must install)

          Win98SE
          BMIDE (check)
          IRQ Router (check)
          AGP (must install)

          As you can see, the AGP GART driver is a MUST no matter which OS you're using. The current AGP GART driver comes with Win98 and Win98SE is only optimized for Intel chipsets.

          Don't expect an Athlon system will do any better for you, if you're ignorant to update the drivers. Athlon platform is even newer than SS7 platform, that even the latest Win98SE provides none of the three critical drivers mentioned above.

          And, I think TurboGL cannot be used with AMD K6 series of CPU where 3DNow! is not available. You won't get stellar performance out of your system currently even if you manage to solve the conflict and enable bus mastering, due to the CPU bottleneck. Anyway, it will be much better than your current situation.

          Here's the URL of ALi website, for you to find further details and download essential drivers. http://www.ali.com.tw/

          Hope this help.

            Sorry, I forgot about the os and chipset. I'm running win98 se and have an ali chipset. As you have mentioned, I've downloaded all the updates and have updated all the latest drivers being an "ignorant" guy who can't do this stuff yet expects better results from an athlon. Just so you know, 3dNow! is available with the K6. I will try these updates again though. Thanks

            BTW, I just remembered. I came home one day and found that my roommate was trying to update my drivers for the VIA chipset. I reinstalled the ALI one, but could there be any residual crap in there and how (if there is) can I take it out? Will clean install of win take care of this?

              Check this, if I still remember correctly,

              HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic e\VxD

              Delete all non-relating GART entry, such as
              VGARTD.VxD (Win98/SE default.)
              VIAGART.VxD (VIA GART, should you accidentally install the wrong ones.)

              Use Windows Explorer to perform a search in your Windows directory and delete all the non-relevant GART drivers.

              If you may need to reinstall Matrox Powerdesk drivers, follow these steps:

              1. Unzip Matrox drivers into a blank directory.
              2. Get UN_513.zip to fully uninstalled previous drivers. You will be asked to reboot.
              3. When Windows restarts, new device will be found. Point to the directory which you have unzipped the drivers and select the correct hardware.

              4. On next reboot, delete the VGARTD.VxD file and its entry from registry as mentioned above. (Every installation of Matrox PD will put back the standard GART. If you have Norton Utilities, you can run System Info and sometimes see two GART loaded. It didn't cause any issue in my system, but I don't know yours. So it's better to get rid of it.)

              5. Reboot.

              Of course, a clean install of Windows 98 SE will solve most of the problems if you don't mind doing so.

              TurboGL will not work with PD5.41 on my system which is AMD K6-2 and MVP3. I don't know it's a chipsets issue or CPU issue. If it doesn't work for you as well, follow the reinstallation process above and install PD5.30.

                kjliew - will try all of your suggestions. Hopefully one of them will work, eh? I would really LIKE to be able to enable BM. Thanks for your help.

                  I did all that stuff (again) and still nothing. I can run my desktop and everything else just fine, but games (UT for ex) crash all the time. I can fly around before I actually hit the fire button for a seemingly limitless time but that's about it. Doing so also makes UT extremely boring after a while... Maybe there is a bios change I have neglected? I've disabled all the video shadowing, the pipeline fcts, and everything else that is on the Matrox help faq. Should I disable the AGP Read burst or one of those type of things? Thanks for your help again.

                    Do you update the G400 BIOS to the latest version?

                    Do you update the motherboard BIOS to the latest version?

                      Yes, everything is updated to the latest version. I just downloaded the mobo bios again and will try in a little while (just to make sure), but everything is using the latest downloads. Other ideas?

                          Could you list your BIOS options in chipset settings, something like:

                          Primary Frame Buffer
                          or
                          VGA Frame Buffer

                          It might have an effect...
