XBMC4Xbox

I have come across a load of xboxs and a few of them were chipped, Ive only ever had a softmoded console and my knowledge about chips and flashing them is very little. Basically I have two xbox as in the attached picture, both hasve the same chip installed but one of them has a a small switch controll panel at the front and the other one is missing. The machine with the controll panel (only 40gb) does boot up but the other one does not, ( but will when I attached a switch control panel).

Are there places where I can get one of these pieces or is there a mod or alternative way of boot the machine to read the chip.

that is an xecuter 2.6 modchip

you could try to hard wire it to boot a bank below is the info I believe on the functions of the pins of the bank switch.

Pins 1 & 4 - On if bank switch is set to 1, off if set to 2.
Pins 2 & 4 - On if chip is enabled, off if disabled.
Pins 3 & 4 - On if flash is protected, off if unprotected.
Pins 5 & 6 - On if chip is enabled, off if disabled.

Thanks for the clarification!
