wow... this must be one of the useless (except for the skin, that's awesome) ideas ever.
there is no reason for a bios cd, just to "keep your favorite bios".
in evox, just put the following line in evox.ini and it will list all the bios' in c:\bios\
Item "Flash BIOS",ID_Flash_Bios
just name your bios files correctly like this, and you should be fine:
M8.bin
M8__67.bin (or M8_67.bin)
M8_16.bin
M8_16_67.bin
M8plus.bin
M8plus__67.bin (or M8plus_67.bin)
M8plus_16.bin
M8plus_16_67.bin
or if you have extra features in it something like this:
M8plus_16_67__BlueX_RedLed_WhiteXboxLogo.bin
or however you want, just so it makes sense.
anyways, keep on making the skin, as that is really cool... but the bios cd is quite unnessary... in most situations.
you would already need to have a bios on a CD or HDD to flash over the default cromwell bios.
it's much easier to have that menu in your evox.ini anyways.
the only reasons i see use for this cd is if the xbox owner does not have a computer, and needs a new bios for a bigger HDD or something. OR if your evox menu is completely idiot/child-proof where all advanced settings are on the cd, and only play DVD, copy DVD, play game on HDD, reboot, and shutdown (maybe XBMC) are on the menu with FTP, Telnet, and all that turned off.
but those arent most cases, and that would require more than your CD.
i think that this project is quite usless, but thats just me. nice skin though.
