Minimum memory adresses set for MS-DOS?

[superfury]

What are the minimum memory adresses (16-bit segment:16-bit offset, e.g. 0x0000:0x0000-0xFFFF:0xFFFF) MS-DOS needs to run, on a 8086 emulator?
E.g. what data is needed to be present in memory (and their adresses and default values if possible) to run MS-DOS?
