Image for UEFI (IFU) requires the following:
--------------------------------------------
* UEFI x64 (UEFI x32 is not supported)

* UEFI 2.1 or later.


Global Options Unique to IFU:
-----------------------------
/da (DismountAll):
  Dismounts the drive letter provided by IFU via the UEFI file system.

/ddio (DASDDirectIO):
  Use direct IO to access hard drives instead of generic UEFI IO.

/odio (OptDirectIO):
  Use direct IO to access optical media instead of generic UEFI IO.


Notes:
------
We have not yet found a UEFI system that is feature complete and stable. 
Consider this to be a warning that the state of the UEFI environment is on 
the bleeding edge.

Hot swapping can cause problems.  While we have used techniques to help 
prevent problems, the methods available under the UEFI environment are 
geared more for a simple single driver than a complex application.  Due
to bugs and conflicts within UEFI itself when employing those methods, we 
needed to revert back to unsafe methods on occasion for things to be usable.
Therefore, we recommend you attach your devices and leave them attached
while using the software.
