I'm looking for all those neat memory locations and what they do. For
example, here are a few:

ffff:0 - jump here for warm/cold boot
ffff:fffe - machine ID byte
0040:00f0 - Keyboard type (0 older keyboard, 1 extended)
????:???? - keyboard status word (numlock, scroll lock, etc.)
????:???? - stores address of beginning of video memory.

Does anyone know where I can find THE definitive list of the? A book or
text file that someone has compiled will do fine. Thanks.
