The basic addressing in 16-bit mode is clear?

You can address with 16 bit 64K to address more memory you need

Segment:Offset

enspeaking

mov reg, offset 

determines the offset, i.e. the distance, to the base(address) of the segment (relative address) udn mov moves it into the target register.

DS:DX would be the address of msg (if msg is in the data segment).

As usual in memory: 1024 as a factor.
