It WORKS!! *sheds a tear*
Ok here's the breakdown...
I have a modded pal xbox converted to ntsc using enigmahs video switch disc, because i needed the prog. scan output for my vd-z3.
After much research I decided to make the jump; install linux (I wanted a cheap webserver!)
I used the ftp method to install gentoox all was going well.
However when I got to my first boot, I got the flashing orange led fan going wild thing: gentoox wouldn't boot!
After much trying, I followed Trevante's advice used the composite cables connected to a tv. I got through the setup however it got stuck at a message (i don't remember what it was, i think something with the network settings)
So after a lot of permutations, I switched back to PAL, resulting in color gentoox boot screen, and voila I got through! However this was in composite mode!
anyways to make a long story short: I switched back to pal mode connected the component cables, remembered which buttons to press to navigate to gentoox in evox (in pal mode, i can't see the evox menu --> no prog scan), started up gentoox and voila gentoox in 720p! It might seem simple, bbut i was literally pulling my hair out!
Next frontier booting gentoox while in ntsc mode! How can I tell gentoox I have an ntsc xbox, again?! During setup, it asked for it (I chose pal

) but now I want to switch to ntsc, so I can use the switch disk again, so I can see evox again(*sigh*)!
What command should I use??!
ps: You won't be having this problems, if you do a native install, I guess!
