Any way to fix one bios that had a bad flash on a white duox 2 mod chip.

Ok, I have 2 bios's on my white duox 2 mod chip, one dosent work becasue i did not double its size and the other bios works just fine and boots up to evox. Is there any way I can fix the other bios??? when i boot it up on the bad flashed bios nothing comes up on screen it just flashes red and green on the power led. Thanks for any help. i just want to be able to have 3 working bios's total (m8_16, original, and possibly one to boot linux or something else cool)

Thanks!!

 

truthfully you should just delete it, find a BIOS that works and use it. You do not need more than one BIOS. There is really no reason for it. Personally i do not care for the M8 too much unless it is the modded version where they added the In Game Reset to it.
My DuoX2 with just one BIOS does everything that i have wanted it to do.
