I want the answers for this questions

2. Question 2: Develop a sequence of instructions that adds the 8-digit BCD number in AX and BX to the 8-digit BCD number in CX and DX. (AX and CX are the most significant registers. The result must be found in CX and DX after the addition.) 3. Question 3: Develop a sequence of instructions that scans through a 300H-byte section of memory called LIST, located in the data segment, searching for a 66H. 4. Question 4: Develop a sequence of instructions that searches through a block of 100H bytes of memory. This program must count all the unsigned numbers that are above 42H and all that are below 42H. Byte-sized data segment memory location UP must contain the count of numbers above 42H and data segment location DOWN must contain the count of numbers below 42H. 5. Question 5 - chapter 9 a) What happens when the HOLD input to the 8086/8088 is placed at its logic 1 level? b) Which bus connections on the 8088 microprocessor are typically demultiplexed? c) If the CLK input to the 8086/8088 is 4 MHz, how long is one bus cycle? d) How much time is allowed for memory access when the 8086/8088 is operated with a 5 MHz clock? e) What main function is provided by the 8288 bus.controller when used with 8086/8088 maximum mode operation
