Routine Description:
Reads the next keystroke from the input device. The WaitForKey Event can
be used to test for existance of a keystroke via WaitForEvent () call.
Arguments:
Private - The private structure of WinNt Gop device.
KeyData - A pointer to a buffer that is filled in with the keystroke
state data for the key that was pressed.
Returns:
EFI_SUCCESS - The keystroke information was returned.
EFI_NOT_READY - There was no keystroke data availiable.
EFI_DEVICE_ERROR - The keystroke information was not returned due to
hardware errors.
EFI_INVALID_PARAMETER - KeyData is NULL.

Returns a 64-bit Machine Specific Register(MSR).
Reads and returns the 64-bit MSR specified by Index. No parameter checking is
performed on Index, and some Index values may cause CPU exceptions. The
caller must either guarantee that Index is valid, or the caller must set up
exception handlers to catch the exceptions. This function is only available
on IA-32 and x64.
@param Index The 32-bit MSR index to read.
