I am using Asus Z270F and was thinking about getting the i9 9900k but it seems 8 & 12 thread is the limit for this motherboard. (bios v.1301 & v.0906) So I guess i7 9700k will make more sense.
I tried @revlaay 's AIO but got an error at “insert CPU microcode” step. However, @svarmod 's Coffee Time seems to work fine.
I did the auto update, unlock region, but not sure if I need to do the “Setup/transfer MAC Address and personal data”. Can anyone confirm?
Also I think CPU pinmod is required. Or there is an alternative motherboard mod?

I made port-bios from Z370-F, it will work with any Sky/Kaby/Coffee CPUs, including 9900K.
Do not forget to transfer personal data from your current bios dump (using CoffeeTime or FD44Editor).
Yes, pinmod is required for any U0/P0/R0 Coffee Lake.

Oh wow, thanks for the port-bios. You basically just tempt me to spend another $85. lol
If the mod bios is successfully flashed, is that mean I can go ahead and buy the 9900k?
Any method to check the compatibility before putting the actual CPU? CPU-Z? Dump the microcode?
As for the personal data transfer, I guess I will do it once I run Coffee Time on the actual board.
(I was messing around with the official bios on my laptop currently.)
I tried to use AFU to flash the bios file (transfer the mac address into the z370 port ) but still got the "4 - Error: ROM file ROMID is not compatible with existing BIOS ROMID.". I will keep digging more…
@revlaay thanks for the kindly help,my new 9600K R0 will arrive next week,I generated but meet a C++ error,but finally the file is generated ?will this still work ?

I got this ASUSTeK_STRIX_B250G_GAMING_1205.U0P0.HT.bin generated BIOS, can i flash this via official updater in current bios? Is it still support Kabylake after that. Thank you!

seems the process has some error happens, output filename not include microcode.
I update new ssf.exe file, slow down the process, please try.
I ran Coffee Time with your given file, install NVME fix, transfer mac address but leave other option unchanged. Finally, I manage flash my bios using AFUDOS. Now, my z270f is showing z370f v2001. Time to buy 9900k?

Still error in vbios step? I tested on my win7,it works.
@revlaay yes,same intel BMP tool for vbios,I checked date for ssf.exe is still 0603 old,only 7cpu-patch is 0621 ,is that expected ?
