Well I flashed it onto my MSI X99A Godlike and it works as far as it not failing to post but have not tried bifurcation with his rom. Seems like he went into a lot of effort modifying custom menus. Here is his github: github.com/Dok-T/MS-7883/
and here on winraid:
[Offer] Ultimate Optimized MSI X99A Godlike Gaming (MS7883) BIOS mod
States compatibility with the Carbon but not sure about your board.
