    DH67CL no video during boot

    qsync

      I finally got my DH67CL (h67 chipset) onboard video working with dual screens in Windows 7.

       

      Then I booted and ran a Fedora12 live CD and that went fine (have Win7 64bit installed).

       

      After booting the fedora cd, now whenever I reboot, I don't see any video until the "starting windows" screen appears.

       

      I don't see the Intel bios splash screen ("Press F2...., etc.") in other words.

       

      I tried unplugging the 2nd monitor, and I tried booting with the DVI connected with an adapter to the analog vga input on one of my monitors.  Neither worked.

       

      The system boots into Windows 7 just fine, though.  I just can't use the bios menu anymore (because I can't see anything).

       

      While trying to get dual screens to work, I updated the bios to BLH6710H.86A.

       

      Am I supposed to downgrade the bios?  Or wait for a new one?  Any other suggestions please?

       

      My cpu is an i7-2600k if that matters.

          Hi,

          Have a look at the 3 pins connector with a jumper set to "normal" position and just change it to the opposite side to get "configuration" position.

          When in this position you reach the bios after power up without any action to do.

          This 3 pin jumper is close sata1 connector, it is documented on the configuration label.

            I don't want to sound lazy, but I didn't try it.

            The reason is that I think setting the maintenance mode jumper
            position is for getting you into the bios if you lost the bios
            password.

            My problem isnt't that I can't get into the bios.  If I press F2 at
            the start of booting, it doesn't continue to boot.  So I think I must
            be at the bios menu, I just can't see it.

            I think somehow it maybe got set to always use the hdmi during post.
            Either I did it by accident (I was careful not to change it from auto
            detect though), or maybe the probing Fedora12 did during boot caused
            it to change.

            I was never able to get it to display over hdmi during post before
            (even if only hdmi was connected), but I was able to get dual screens
            working in windows.

            I think maybe my best bet to get the display back during post would be
            to clear cmos.

            The problem with that is that I think changing the video memory size
            from "maximum" to 256MB may have been necessary to get dual screens to
            work in windows.

            My theory is that the bios does not correctly initialize the hdmi port
            for my monitor, so if it's set to "use maximum" it doesn't detect the
            monitor, so it allocates only enough memory for one display, and
            subsequently only one display can be used in windows.  I think when I
            set it to use 256MB, it always allocates enough for two screens, so
            then the display driver tries to initialize the hdmi port and it sees
            the 2nd monitor then.

            So my fear is that if I clear cmos, then if I still can't see the
            display during post, I won't be able to change it from "use maximum"
            (which I think is really "auto") to "use 256MB" for video memory, and
            I won't be able to get dual screens working again.

            So, I think I'll just cross the bridge when I come to it (try to make
            it work when I actually have to change something in bios).

            I'll try the next bios update too.

              I installed the new bios update (installed it from Windows)

               

              BIOS Update [BLH6710H.86A]

              Date 4/15/2011

              Version 0110

               

              And now I have video during post/boot and can use the bios setup menu again.

               

              The video now displays on both monitors during boot.

               

              Dual screens in Windows are still working.

               

              The update reset the video memory size to "maximum" and it still works (I had changed it to 256MB before when I was getting dual screens to work in Windows).

                    i did as you said but still nothing on screen . The motherboard light , case fans are all working as usual. there is a bios cfg 3 pin on which thiere is a yellow two pin connector ( m not sure abt the exact name) which is conncted from right side which leaves a free pin on left side. i tried changing this connector around but no difference.
