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.

KS,
If you go by the formal definition for this parameter, you are absolutely correct; the type 41 record for the second NIC should have Device Type Instance (DTI) set to 2 (second device of this type). If you go by the example that they include in the SMBIOS spec, however, there's a problem -- the example states that the NICs need to be "identical" before the DTI is required to be set to 2. It could be argued that the 82579LM and 82574L NICs are not "identical". Still, I agree with you; the wording of the example is just unfortunate. I am having a defect report opened...
