Help w DZ68DB bios. Restore to factory default without display.

I recently bought a DZ68DB board and core i7 2600 processor to upgrade my photo workflow desktop.

 

After the initial setup I experimented with different bios video settings for a dual display setup with the onboard IGP and the xtra GPU, ending up with a configuration where BIOS post messages are not displayed for some reason, probably a missconfiguration. Video starts only when  windows starts. Before that none of the post messsages (Intel logo, press F2, etc..) appear on the display. THe display btw is connected to the DVI port of the IGP.

 

I would like to reset the bios to factory defaults. Since I cannot see whats  on screen I will need help. Can anyone send me the extact key sequence after power on so that I can navigate without seeing the screens to complete the reset to factory defaults?

 

Already tried clearing CMOS data by removing battery and reflashing BIOS w/ update w/o success.

 

Thanks in advance.

    Hello Andrei,

     

    I see that you made some changes in BIOS and now you are not able to load the BIOS defaults.

     

    At this time there are several ways to proceed, the first one will be to properly clear the CMOS by removing the power cables and the CMOS battery for an hour.

    The second thing to try will be moving the BIOS jumper from pins 1-2 to 2-3 and turning on the system like that, it should take you in to maintenance mode in BIOS and there you can load the defaults. If you don't get any display like this, wait for a 1 minute after you turn on the computer with the BIOS jumper on pins 2-3 and press F9, then press the letter Y and then press F10 and the letter Y again. Wait for 10 seconds then turn off the system change the BIOS jumper to its original position and boot the system up again.

     

    Hope it works for you.

     

    Regards.

    I am experiencing the same issue.

     

    Once I try to use the onboard IGP, the output video signal won't start, until the OS starts, so there's no way to put the setting back or change anything in the BIOS anymore, unless by using the BIOS Configuration Jumper.

     

    Also, the OS cannot start properly at all. I am using 3 operating systems (Kubuntu + 2 Wins), with a GRUB in front. Kubuntu tries to start, but then the X server dies with an "unable to detect monitor" error message (or similar). If I chose Windows, the system just reboots.

     

    Does the onboard IGP work at all and how?

    1) Power down the system.

    2) Change the BIOS configuration jumper (yellow jumper above the STDBY LED) from RUN (jumper on pins 1 & 2)  to CONFIGURE (jumper on pins 2 & 3).

    3) Power back on the system.

    4) The system should display the splash screen and then go into the BIOS configuration automatically.

    5) Change the IDG Primary Video Port to <Auto>.

    6) Change the Primary Video Adapter to <Auto>.

    7) Exit the BIOS.  The system will prompt you to power down the system and return the BIOS configuration juumper to RUN.  Do as instructed.

    8) The system should now start normally with the BIOS splash screen showing when the system starts up.

     

    See http://communities.intel.com/message/136045#136045 .

     

    If the above specific BIOS settings don't work for you, then follow the same process but modify the video settings as needed.

    Well, as I already mentioned, I recovered by using the jumper, but still - I cannot access the BIOS once I change to the IDG (either HDMI or DVI) again.

     

    Did you manage to find some solution for that?

    Let's make sure we are on the same page here...

     

    BIOS recovery means (at least to me) flashing the BIOS.  This can be done many ways including the use of the BIOS Configuration Jumper.  I'm not suggesting to do this as you have already stated you have done this.

     

    What I am recommending is to get the system in to a special BIOS 'safe' mode where hopefully you will able to make modifications to the BIOS settings.  This is done as outlined in the steps above.  No attempt to re-flash the BIOS is made when the system is in this mode.

    Well, I am able to enter the BIOS again, by moving the BIOS Configuraion jumper. But still, I am not able to do it when using the onboard IDG - it gives output to the display only when the OS starts, not before that.

    I've seen my system also not show the BIOS boot screen before too but yet the display starts when Windows start.  You will need to change some settings -- again with the BIOS configuratoin jumper set.

     

    Try the following settings:

    Integrated Graphics Device:  Enable if Primary

    IGD DVMT Memory: Maximu DVMT

    Primary Video Adapter: Auto

    IGD Primary Video Port: Auto

    These are the default settings and it does not work that way - the video signal is sent to the PCI graphics card only.

     

    I have tried all the possible options, including:

     

    Integrated Graphics Driver: Always Enable

    IGD DVMT Memory: Maximum DVMT

    Primary Video Adaptor: Auto

    IGD Primary Video Port: Auto

     

    and

     

    Integrated Graphics Driver: Enable if Primary

    IGD DVMT Memory: Maximum DVMT

    Primary Video Adaptor: DVI-I (Blue) Analog

    IGD Primary Video Port: DVI-I (Blue) Digital

     

    In both cases the display stays black during POST and Grub and starts only when the default OS boots.
