Strange message after BIOS Update

Discussion in 'DIY Computers' started by Enrie Membership, Mar 19, 2006.

  1. Flashed the BIOS on a Asrock 775VM800 motherboard. On start-up the
    message 'mac address are invalid in both apc and flash' 'please press F1
    to continue'

    When I press F1 the machine boots and runs normally but the message
    returns at each re-start.

    I have re-flashed the BIOS back to the version that came with the board
    but the message remains. I have re-set the CMOS and checked and
    rechecked the settings but can't see anything that seems out of place.

    Any suggestions?

    Look at this thread

    This also seems relevant, even though it is a different motherboard.

    Question: My motherboards are K7VT4A+ and K7VM3. During the POST, it shows
    "Mac address are invalid in both CMOS and DMI. Press F1 to resume". What
    should I do?
    "Answer:please try to install your CD-ROM, CD-RW, DVD-ROM, or DVD-RW to
    primary IDE (IDE1, blue connector) and install your hard drive to secondary
    IDE channel.
    If you still encounter problem, please download the tool to rewrite the MAC
    address from:"

    Run "ipconfig /all" and more than likely it'll show your mac address as
    After a BIOS flash (or changing the CMOS battery) this is common with ASRock

    To correct this, enter the CMOS settings with F2 at boot, then load the
    default settings on the exit screen.
    This should restore a valid mac address.
    Then put back your custom CMOS settings.

    I've seen this on quite a few ASRock boards.
