What mode is this?

Win7 64bit full kernel crash dump shows “16.0: kd>” as command prompt.
I know 0 is processor number but no idea of “16”

Another weird thing is “dd” command print as follows like 16bit debug.exe.
0000:0000 ??? ??? ??? ???
0000:0010 ??? ??? ??? ???
0000:0020 ??? ??? ??? ???
0000:0030 ??? ??? ??? ???
0000:0040 ??? ??? ??? ???

Thanks for your valuable answers in advance.
