8 Core Impact Bios

Hello, I am interested in making an 8 core capable bios for the Maximus VIII Impact. I believe there is already a 6-core bios available:

A user says this bios doesn’t work with his 9900k. How would I implement 8-core support? Also, how could I PREVENT Sceptre/Meltdown fixes (slightly lower benchmarking performance)?
Thank you for any information. I am new to this forum.

@AutisticChris - You need to ask in one of these threads, but if I remember correctly currently there is issues without resolution for 9900K and Asus
