Thanks for the info guys.
If I ever decide to put the 940 back in my case, I'll try the settings you suggested, froxic.
Currently, I'm using a PII 550 BE oc'd to 3.6 GHz on 1.40 vcore. Also, I was fortunate enough to unlock the other two cores with ACC.
When the NIC issue first started, I tried resetting the CMOS but no luck with everything returning to normal. What's interesting is that my router detects the port in gigabit mode. But when I check the cable status in the BIOS it says something about testing a virtual connection as if there is no connection. I may try resetting the CMOS again just to be sure.
