[Offer] Ultimate Optimized MSI X99A Godlike Gaming (MS7883) BIOS mod

Hi everyone, my first post here.

I offer you guys my custom bios.

Here’s the link with changelog and all the stuff.

Also if anyone can help me to implement correctly the IntelRCsetup it would be really great tho. Finally got it unlocked ! Please see credits

The repo also includes schematics and stuff i used to make this mod.

NOTE: this bios mod might be compatible with the X99A Godlike Carbon with corssflashing but not tested as I don’t own this board

Patchs / Features added:

  • Unlocked menu (IntelRCSetup and an other one)
  • Updated Microcodes (please see Updated Firmwares section)
  • Updated OROM Firmwares
  • Unlocked some hidden settings in regulars menus
  • Boot by default using UEFI only and FastBoot
  • PCIe bifurcation made possible trough IntelRCSetup and more configuration under Settings → Advanced → PCI Subsystem Settings such as CPU PCI-E Lanes Control) PLEASE READ PCIE HW LIMITATIONS SECTION!!!
