Difference between minimum & maximum mode from control signal perspective

Question
What is the difference between minimum and maximum mode from the control signals perspective?

Answer
In minimum mode, all control signals are self generated by 8086/8088 microprocessor such as RD' and WR'.

In maximum mode, the control signals are generated by external chip such as MRDC' (memory read) and MWTC' (memory write) by 8288 chip.
