Minimum mode describes a chip configuration where the 8288 bus controller is not required. Certain signals, such as ALE, are then generated directly by the processor. Maximum mode describes a chip configuration where the 8288 bus controller is required. The 8288 generates ALE, and other signals, allowing the processor to provide other signals, such as LOCK. These two mode allow the system designer some freedom, and allow the number of pins on the chip to remain lower.
The two modes of the 8086/8088, minimum mode and maximum mode, have nothing to do with segment arrangement. The modes determine which pins on the chip have which functions. In minimum mode, certain pins are sacrificed in favor of a smaller implementation. In maximum mode, those pins take on other functions, and the original functions are generated by the Bus Controller chip.
minimum mode and maximum mode
The 8251 is a USART (Universal Synchronous Asynchronous Receiver Transmitter). It does not have a minimum and maximum mode.

The range of a single number is 0.The mode, median, maximum and minimum of a single number is the number.
Minimum mode in the 8086/8088 provides the functionality of the 8288 bus controller, which means that functions like HOLD, HLDA, WR-, M/IO-, DT/R-, DEN-, ALE, and INTA- come off of the 8086/8088. Maximum mode means that these functions come off of the 8288, in somewhat enhanced form, and the pins are replaced with new meanings like RQ-/GT0-, RG-/GT1-, LOCK-, S2-, S1-, S0-, QS2, and S21, giving the processor extra capabilities.
Range = 0Mode = 3 Median = 3 Maximum = 3 Minimum = 3

8088 processor accessed 1MB
The 8086/8088 processor is a 16 bit processor. In a 16 bit two's complement notation, the maximum number is 0x7FFF, or 32767, while the minimum number is 0x8000, or -32768.
The MN/MX- ping on the 8086 is pin 33.
1:in min mode mn/mx- is connected to vcc .here now mn will be one AND IN MIN MODE ONLY ONE PROCESSOR IS PRESENT WITHOUT ANY CO PROCESSOR . 2: in max mode mn/mx- is cnnected to ground now the mx will become 1. AND IN MAX MODE MANY PROCESSORS ARE CONNECTED TO EACH OTHER WITHOUT ANY CO PROCESSOR EX FOR COPROCESSOR IS 8284 1:in min mode mn/mx- is connected to vcc .here now mn will be one AND IN MIN MODE ONLY ONE PROCESSOR IS PRESENT WITHOUT ANY CO PROCESSOR . 2: in max mode mn/mx- is cnnected to ground now the mx will become 1.
