I’ve successfully installed Windows 7 RC on my Viliv X70. I basically followed the directions in Viliv X70 – Windows 7 on the X70 – Tutorial that I mentioned in Viliv X70 – OS Clean Start?. However, there were some glitches. There also are some unresolved issues. My plan is to resolve those issues in the next few days and then document the process this weekend when I have some free time.
