Hello and welcome!
It seems you have used AI to create a forum post. In essence, the six final points you list are all fulfilled by the modded BIOS I provide. Some comments:
- Please do some real research. D8 does not use 1.5M ME region, but instead close to 8M like on almost all Chinese X99 boards
- You clearly state that you have flashed an old Huananzhi F8 BIOS on it. Yet somehow you are surprised that it does not identify as Jingsha D8 any longer. I wonder if there is a simple explanation for that?
- You will put together your own BIOS, not me. In your particular case it is very easy, just follow “Example 4”. As a matter of fact, this is all I needed to do myself for my Jingsha D8I
- Bifurcation is hardware dependent. Since I do not own the hardware, I do not know how IIO maps to the physical PCIe slots. BIOS certainly supports it, but you have to try yourself
- TBU is provided by BIOS “B2”. Undervolting is set in the BIOS instead of hardcoded in a separate driver like in most guides
