Xbox:XeniumOS
 | This process is dangerous and potentially can brick or fry your Xbox. It involves soldering a very small contact, so it is recommended to be experienced with soldering before proceeding. |
XeniumOS is the BIOS that comes with Xenium chips and runs on OpenXenium. It can also be run standalone on a HDD as an application, though it is primarily a recovery menu in which you can configure virtual BIOS banks (for modchips), edit your hard drive configuration, and change your EEPROM settings. The official user guide for XeniumOS 2.0 can be found here.
