Use evox's backup feature and then copy the bios.bin file it created on the hard drive to you PC. Open the bios file in XBTOOL and see if it recognizes it. If it does all you need to do then is get the MD5 string at the top of the xbtool window click "Copy MD5 to Clipboard" button.
Now open your evox.ini file from your xbox and look for the section labled
[BIOS] then create a new line under that section like this
ROM = "XXXXXXXX",0xYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
Where XXXXXXXX is the name you want it to list as in the evox dash.
and YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY is the MD5 that you got from XBTOOL.
there should be other examples of this line in the evox.ini already. Just use them as a guide line for your bios.
Once deon save the newly edited evox.ini and then reboot the xbox. It should now list your bios.
