    Why does DQ77MK SMBIOS have same Type Instance = 1 for both Ethernets?

    KS_Johnson

      Both onboard Ethernets on the DQ77MK seem to have the same type instance number. This seems to cause problems with Linux biosdevname making it think there are duplicate bios names for the ethernet devices and fails to return a valid name. Anyone else run into this problem? I'm trying to qualify a new board for production with BIOS 054 and did not see any reference in release notes for subsequent BIOS updates that changes this data.

      # SMBIOS entry point at 0x000f04c0

      SMBIOS 2.7 present.
