This is the chip used: M27C4001-10F1
And two photos:


The chip.


And the cables that run to the motherboard.
I want to put a VGA BIOS on my XBOX, but as long as i can see the only option for me with that kind of modchip is to flash it with UV light, and then use a programmer to flash the new BIOS on it or TSOP the box.
If someone confirms my suspicions, i guess i'll be posting in the TSOP thread soon
Thank you in advance
