    1B14:0091 = 1000:B1D1 = 1B1D:0001 = ...

    yes, infinite ways.

    However the preferred method is to have it your way, the offset
    (number before : is segment, number after : is offset)
    is between #0000 and #000F. It's called normalized address.

    Some circumstances require that the segment be fixed, and so you
    have to resort to using greater offsets...
