That error code corresponds to EFI_SECURITY_VIOLATION being returned by 
the call to ConnectController().  (With the latest iPXE code, you should 
now get the error http://ipxe.org/7f37e19a instead.)

There's no obvious reason why your platform firmware should be claiming 
a security violation, but it's probably worth checking through various 
BIOS setup screens to see if there are any security-related options that 
could be disabled.
