Thanks for the updates folks.
I guess from what I have learned I could order the Aladdin XT and flash it with the HackDaBox cd I already have downloaded, or get the DuoX 2 Cromwell and flash it myself in case I ever learn more and can take advantage of the 512K BIOS.
If I did get the DuoX 2 Cromwell how would I go about making sure I have the correct BIOS downloaded? You have mentioned the X2.5035 BIOS. Who makes this BIOS? I have heard of Xecutor, is this the company? If I do download it, how does the http flashing method work? Do I just point the browser of a computer on the network to the IP of the Xbox and follow the prompts?
Also, will the Cromwell chip allow a normal Xbox hard drive to boot as it is so I know the install went OK, or do I have to flash it before the box will work at all?
Thanks again for all of your help, it is at least starting to make some sense to me now.
