I am having an issue with an Asrock Z270 Killer SLI. I’ve gone through the process starting with “Adding FFS module.” I was able to flash the modded bios - after removing the Security Flash Check. I can only get it to boot without my GPU (Asrock Arc A380) installed, and only with 4G disabled.
I used bios version 2.30, asrock dot com/MB/Intel/Z270%20Killer%20SLIac/index.asp#BIOS.
Any thoughts on next steps to try, or just relegate this MB/CPU to another purpose and get a newer system?
