EvoX baffles me

[The KeeN]

Thanks for the help, I have been on your site quite a few times in the last few days, very good info there.

I wondered, if I install my chip today and flash it with the X2 4781 bios, then boot the xbox up.
What will it do ro look like and what does a mod chip in the Xbox actually do?

Sorry for sounding dim but I am new to the Xbox scene as you can tell, I am a PC an d PS2 man normally but have been very slowly converted.
