770X Bios Flash Without Good Battery?

[Calascio]

Anybody know of a way to flash the bios on a 770X without a working battery? I know I've seen a method somewhere but I can't find the site.
Thanks.

I'm trying to find a way to upgrade the bios on my 770z without a good battery. There is a way to do the 600 series but the file names for the 770x and 770z are different. I'm pretty sure that it will not work the same way.

If anyone has an idea or knows of a way to do this, please let us know.

Thanks.
