Hi KGP,
thank you for your assessment. I think too that there is the need of a few microcode/ME-Updates from the board manufacturers. The X299 Taichi XE UEFI for example is from late 2018, the one from the Prime X299-A is from 02/2019 anyhow. But confusingly enough W10 is booting, so there is obviously a HS/Mojave kernel problem with 9820X and newer 9900X (maybe not newer but specific revision).
Not necessarily, as any BIOS firmware is optimised for Windows at first place. If you look at the recent post #2,716 of @mcitiy, his i9-9900X is properly working with the ASROCK X299 TAICHI XE under HS, thus I would exclude any HS/Mojave kernel problem and I also doubt that there are actually different versions of the i9-9900X distributed by Intel.
Anyway, I guess one should really address such issues directly to the manufacturers, whereas any respective discussion here might not really help in this case.
