And is this non-standard interface out there in the wild or only at Intel's labs?
Are there boxes like that out there?
If I go to the store and buy a box, how do I know whether that box would need "nocfg"? Do I look in the BIOS or how do I find out I need to supply "nocfg"?

How do I find out that the serial port is configured?
And don't give me that "example" about the typing on keyboard or on touch screen again.
