A mate's just bought a second-hand v1.4 Xbox which was already modded with a DuoX2 GS

The chip doesn't have a Bank 0 - Bank 1 switch and there's no sign that the BT pad has been soldered to pin 9 for the Always Enabled function.


If it doesn't have a Bank Switch then it might be a Duox2 Lite.

I did run a BIOS app and it showed the same checksum for both 512Kb banks and as I recall the 256Kb banks all had the same checksum as well. Does this mean that both banks have been flashed with the same BIOS?



How are you checking banks when there is no bank switch?

I guess it could be the Lite. It has an AMD chip on it if that makes any difference.

Perhaps I'm a bit confused about the banks. It looked to me like BIOSchecker showed 2 512KB and 4 256KB. I can't check now 'cos the Xbox isn't working at the moment but I probably misunderstood it.

Whichever chip it is, something's wrong with it booting the Xecuter2 BIOS when eject is used to power it on, 'cos that's meant to bypass it.
