What are the extra features in protected virtual address mode of 80286 processors?

Protected mode is an operational mode of the Intel 80286-compatible CPU. It permits system software to use features such as virtual memory, paging and safe multi-tasking. It is also designed to increase the OS’s control over application software. This term is also known as protected virtual address mode.

What is true about 80286 microprocessor?

80286 Microprocessor is a 16-bit microprocessor that has the ability to execute 16-bit instruction at a time. It has non-multiplexed data and address bus. The size of data bus is 16-bit whereas the size of address bus is 24-bit. It was invented in February 1982 by Intel.

What is the addressing mode of mov ax BP Di?

1.2. Likewise, if bp contains 1598h and di contains 1004, mov ax,[bp+di] will load the 16 bits in ax from locations SS:259C and SS:259D. The addressing modes that do not involve bp use the data segment by default. Those that have bp as an operand use the stack segment by default.
