first connect the 8255 to the 8086 microprocessor and configure it using the CWR then connect the key board to the 8255
This is too long and complex to just describe in words, you also need a good diagram to show you what to do. There is one at a site called 8085 projects . info.

The Instruction Pointer (IP) in an 8086 microprocessor contains the address of the next instruction to be executed. The processor uses IP to request memory data from the Bus Interface Unit, and then increments it by the size of the instruction.
Command Line Interface
biu stands for bus interface unit and eu stands for execution unit. In 8086 microprocessor BIU fetches the instructions and places in the queue. The Eu executes the fetched instruction and places the result in the registers
A keyboard is a Human Interface Device. This enables you to enter information and commands into a computer by pressing keys in various sequences.
