*
* NKRO may prevent your keystrokes from being detected in the BIOS, but it is
* fully operational during normal computer usage.
*
* For a less heavy-handed approach, enable NKRO via magic key (LShift+RShift+N)
* or via bootmagic (hold SPACE+N while plugging in the keyboard). Once set by
* bootmagic, NKRO mode will always be enabled until it is toggled again during a
