I really had a hard time trying to get the right drivers for Windows 8.
Installing the old drivers from my previous post on this topic failed.
I tried various things like modding old drivers.

Changing the inf files to make it think that it is a supported driver.. didnt work either..
After a lot of looking I found a Windows 7 driver that works perfectly with Windows 8 as well.
Here is the link the download with instructions....

I hope this helps save time for others who are trying to get their Windows 8 PC running on X1400 Radeon Graphics Card.
