Nothing to do with Evox......
Grab HeXEn (Google Heimdall's Xbox Engineering Disc). Burn to DVD-R at 4x or slower. Use it to flash a newer BIOS (Option 3.2), then use option 3.5.2. Clean C partition after TSOP flash, then select option 4.1. Install XBMC to E. Use FTP to delete the current XBMC installation from E:\Apps\XBMC and replace it with the latest version. Reboot and make sure that XBMC works when you run it as an application from the dashboard.
Once XBMC works as an application you can use the dashboard switching tool (either run from the default UnleashX dash or from HeXEn - Option 5.1.4.3 Switch to XBMC on E) to change the default dash to XBMC.
