with the sierra guide
Usb created on an running imac with high sierra with the base installer from the store witch should be version 10.12.6
Used the kernel version 10.12.6 and patched aicpum kext from here
the problem is that it hangs at still waiting for root device with booth usb drives
Bios has been reset to factory defaults and sata mode is ahci mode.
