I used the Enoch El Cap USB creation tool (v2.0) and can get into the installer with the following:
-x
-f
-v
PCIRootUID=0
GraphicsEnabler=Yes
NV_Disable=1
The install works fine (10.11.3) yet I cannot get into the OS without a KP (both USB and NullMGMT). Can anyone elaborate on a viable install process? The system is successfully running 10.8 now.
Thanks,
Follow this, it works. I have an HP Z400 running El Capitan the latest version.

Could you give us some further information about that?
