I recently bought a k7vt6 motherboard and finally got it running
with the exception of being able to access the internet.
At startup before Winxp sp1 loads i get a message saying
"Invalid MAC address in both CMOS and DMI"
In WinXP Sp1 i ran CMD and IPCONFIG /all and my
Physical address reads FF-FF-FF-FF-FF-FF

I then Download a program and purchased A-Mac address changer 3.01
and managed to change the mac address to an addres valid for a VIA Rhine II fast ethernet
it reads it under IPConfig /all but i still get that message at startup and the internet still doesnt work

What do I need 2 do?

Im Pulling out my hair on this one So any help would be greatly appreciated

run Regedit
and open following key
<br>&nbsp;&nbsp;&nbsp; 11CE-BFC1-08002BE10318}

Trere are listed different notwork adapters (0001 ,0002,0003 )
and when you found the right NIC Add the key NetworkAddress(REG_SZ) and enter new MAC adress for example 112233445566

"Physical address reads FF-FF-FF-FF-FF-FF"

Sounds a bit like bad hardware to me. Did it ever work? If no you should perhaps see if you can get a replacement for the mobo (assuming the network adapter is on-board).

alright Winzig i went into regedit and found that folder the only value i find is 00 80 62 c5 c0 01 c1 01
I thought it only had to be a value of 12 characters the value in all folders 001 002 and 003 are the same with 16 characters
is that right???

from the DriverDescription. By the way if there is wrong value in NetworkAdress (16 characters ) for other adapters you can fix them too.
