[Xbox EvoX Fix?]

I hope someone can help, I am very new to this.

I found my original xbox in the loft, when I boot it loads showing EvoX (pink logo) in the top left corner. It then seems to boot open the original dash. I heard the PAL system was locked so you couldn't access the HD scaling. Is there anything I can do to unlock the 720p / 1080i features to get better visuals on my 4k TV?

I found a forum saying I could use a DVD and burn HeXEn bios onto it or something then run that in the Xbox to unlock the features? But when I tried to burn this to a DVD-RW it would not let me on my PC? 

Sorry, I know you probably get this a lot from newbies! 

Cheers.
