What is on this compared to the EvoX that I have (check my sig)? Do you recommend that I update? Or am I just totally off base and M8 has nothing to do with that? Thanks!

The Evox M8 is the latest bios released by the Evox team. You can upgrade if you want. You can use a tool called "EVtool" it's very similar to XBtool to customize your M8

Does it have anything special on it? or that I can do to it?

No the bios Xecuter2 is just as good. But what I found out is the X2 4983 bios can't be used with XBtool to customize it. Xbtool just doesn't recognize the bios but it recognizes the older X2 4981 bios. With customizing your bios you can change the color of the xbox logo plus more.

Alright, thanks for the info

I recomend X2 4983 because of the Xbox Live disable hack, but I think M8 might have that too. if it does I would use M8 for the customization
