Reinstalling your os has nothing to do with bios, you are getting this message long before any hard disks are involved in fact the bios doesnt even have the interrupts running for the USB devices at this point, you'll notice this if you have a USB keyboard. The only possible solution is to flash or replace your BIOS chip - this is a LAST RESORT option. I dont recommend it if the system works other than the LAN. Your best solution is to install a network card in a free PCI slot, they are pretty cheap if you know where to look, heck even goodwill carries them in their 1$ computer junk bin thats where i bought a few of my 100baset cards (of course at your own risk) hope it helps

The MAC address is burned in the Ethernet card chip, you won't see it in the Bios or if you do you can't change it. MAC address changer are tweaks to not being tracked.
The solution to know if the card is blown is to do a complete reinstall of your operating system and if then you can't connect whit it, it is indeed dead. Then Disable it in the Bios and had a PCI one to replace it.
Those kind of problem whit network cards happens a lot when you get a power outage, if you had one in the last couple of days your problem is most likely it.

The MAC is the unique identifier for the onboard LAN chip - if it's invalid then the chip has been fried - disable it from the BIOS and install a new PCI LAN card.
