Can't get to BIOS no matter what I try on DZ77-RE75K MB

[Rob_C_Intel]

I'm evaluating a system for use and this board will not let me get into BIOS no matter what I try. They keyboard seems to work, num lock can be turned on and off, and as soon as I get to where it tries to boot an OS, I can alt-ctrl-del to reboot. I've tried 4 different keyboards, and every USB slot. I've tried moving the BIOS jumper to every spot, I've cleared it by taking out the battery and holding down power, I've tried with the back2bios button on and off. When back2bios is on, it just boots up and tells me to unclick the button, doesn't go to bios. F2 or del do nothing when mashing them constantly during POST. They keyboard(s) seem to initialize immediately because I can turn num lock on and off, I've also tried removing everything but the video card and one stick of RAM. Cannot try with just the built in HDMI because I don't have a cable. Any ideas?

Hello RobCohen, thank you very much for contacting us through Intel Communities.

Since you already tested the motherboard, the recommendation I can give you is to try a BIOS update. There are 12 BIOS versions for this specific motherboard.

The following URL will show you the fixes and features add or update on each BIOS version. http://downloadmirror.intel.com/22828/eng/GA_0066_ReleaseNotes.pdf http://downloadmirror.intel.com/22828/eng/GA_0066_ReleaseNotes.pdf

If you remember which is the current BIOS version of the motherboard, please try the next BIOS version available.

If not, it will be necessary to try an old version first. Then, you will have to flash 3 or 4 versions in order to get to the latest BIOS V066.

Rob,

By the time you see video initializing at your monitor, it it likely already too late to catch the window. Power off the system; then, when you power it back on, immediately begin pressing the key over and over as quickly as you can. You should catch the window then. Why is this happening? As folks have demanded faster and faster boot times, we had to make the windows for accepting function key presses smaller and smaller...

Hah if only it were that simple. Of course I've tried that method a bunch of times. Pressing F2 constantly from the second I give it power to when I see the POST graphic come up makes no difference. Eventually the buffer fills up and I can hear click click click from the PC speaker, but it never enters BIOS. I also can't get to F7 for BIOS update. F10 for boot menu, interestingly enough, does work.

That fixed it! Managed to update the BIOS to latest with iflash2 and now I can get in. Thanks for the tip.

I'm glad it worked. Thanks for letting us know.
