    So, this is a problem with the mobo BIOS and not with the IDE card?
    If that is the case, I'm afraid that I probably won't be able to flash the
    BIOS. Fugutech disappeared a while back, but now they have reappeared, but
    the website contains almost no English so I cannot even find my way to the
    BIOS section (if they even remember this board).
