Answer / Ratnesh Kumar
The Start Of Program (SOP) signal is used to indicate the beginning of a program transmission or execution. In an 8086-based system, the SOP can be defined using the following sequence: 0xFF, 0x01, and 0xCB. To start a program at location 2000h, you would first send the SOP signal by writing these bytes to the I/O port where the CPU expects the SOP.
