I don't know the exact differnce between the LX and BX parts but I believe that the LX only supported up to a Pentium II whereas the BX does a III and a celeron.
Yes, seems to be the main difference (at least from an end user's perspective like mine!) The board only supports up to a 333MHz CPU and it does support a Celeron, but it can't do a 100MHz bus (only 66 officially, but it will go up to 83.)
I that the 440BX code should work for you. I know I used a lot of the LX/TX code as reference when I was getting our board to work. You should at least be able to get a serial port up.
Great, I'll try that then. It's looking more and more like I could just grab the GA-6BXC code and use that! I'm just waiting to get hold of an extra BIOS chip, to extend the life of the motherboard should anything go wrong ;-)
What superIO is on the board? Look for a National Semi chip or a winbond or something similar.
Well, there's a Winbond W83977TF-AW and that seems to be the only Winbond chip. Can't see any Nat. Semi. ones though, so hopefully that's the one you're looking for!
Thanks for your reply, Adam.
