    Default GB Ga Z87X ud5 not able to enter the bios stuck at A9.

    Today I had a very strange problem.

    When I booted my pc and tried to enter the bios environment my screen remained black and
    the cursur was blinking error code was A9.

    Tried to boot from the back up bios but no go, than cleared the bios cmos no go than removed
    DVD 2 hd's and only booted with the Plextor M5pro SSD NO GO.

    Removed the SSD and than I was able to enter the Bios reconnected the ssd and other
    hd's and dvd and now windows 8.1 boots.

    Achi is set and the boot sequence is set at other Os, installed OS via MBR since GPT mode
    gave the the watermark error.

    So has anybody any idea what is causing the bios the freeze up completely, back bios not working
    and only when I remove the ssd I'am able to enter the bios.

    Thanks for feedback and suggestions.

    Just for grins try moving your drives to the Marvell SATA ports and see what happens. My first board had some weirdness going on using the chipset SATA ports. My second board has no problems.

    Just installed F8 mod and so far I was able to enter the Bios without a problem.

    Will check the coming days to see if F8c beta was the problem.

    Could be. I haven't tried the F8c beta.
