ok i was playing a game yesterday and during mid game play a screen pops up saying cant read disc, and i thought it was the disc, so i put an other one in and it also dont read, it just keeps going to the evox dashboard and in the right hand cornor it says bios unknown,
im not sure what modchip is in my xbox, but maybe does the chip or something need reflashed? and why did it just go bad during mid game play?

it's not the chip or anything inside the xbox is your media, i think if u use the silver back 1 they tend to do this a couple of times, if u cant deal with this use good media like ritktech(i think thats what they r calld)
or memorex they both work realy good for me

yes its all about media... you have a crap phillips dont u
