A few thoughts about the picture... Disclaimer: This is only me and my guesses, I have nothing to back this up with.
There is no SATA cable connected, only the power/tray_status/eject cable is seen. The SATA connector can be seen seen to the right of the powerconnector on the back of the drive.
Regarding the pcb in the picture, it's a fairly similiar to the
SeventhSon/Kev schematics. I'm no assembly programmer and only have the basic knownledge of the firmware hack, so bare with me.. Anyway:
- The large black part is a voltage regulator that generates the neccessary 3v3 feed from 5v (a regular molex connector only carries 5v, 12v and ground) that the drive needs.
- The bottom silver like rectangular part is a switch, and if I'm correct, will let you switch between ModeA which is normal mode/xlive/off, and ModeB which is the debug routine that lets you run custom code (spoof the mediaflag parameter that is sent to the Xbox software, i.e dvdxbox360 instead of dvd-r). Note that the switch very well only can be for development purposes of the firmware and not related to xlive. I don't know enough of the inner workings of the firmware hack.
- The board can be a passthrough between the motherboard connector and the connector on the back of the drive, this will let you mount a switch on the outside of the case for easy access to switch between ModeA and ModeB.
- There's proably also a LED on the pcb that will let you know the current switch posisition.
- Xecuter could also provide/manufacture SATA-to-USB, SATA-to-IDE and a powersupply adapter for ultra portability.
