My buddy's machine w 10 year old socket 7 Gigabyte MB not recognized by DNS in wired home network, which itself works fine on other devices. Onboard ethernet adapter AND PCI adapters tried with disabled onboard adapter. Multiple OS types tried, Win 7 also multiple Linux packages. We do see drivers loading. Do not see how this could be happening unless there is something going on with interrupts, BIOS etc. We see 0 bytes received in Win 7 then on another panel show some bytes received, cant remember which panels show these. Of course no IP address is issued
