Which Operating System are you using? I'll be glad to help out since Intel's Official interactive support for the DH67BL has ended.
Here is a working link for the DH67DL driver download page, select "View More" at the bottom and it will bring up the legacy bios. If this doesn't resolve your issue let me know.
I just check the download center and it is working fine, please let me know if it works for you now.
