And so it sets all that up, switches the chip into protected mode.

And in fact the system is not even in protected mode.

The initial protected mode, released with the 286, was not widely used.

Windows 3.0 was able to run real mode programs in 16-bit protected mode.

After its appearance in 1982, the protected mode of the 80286 had not been utilized for many years.

This memory is only accessible in the protected or virtual modes of 80286 and higher processors.

An example would be from supervisor mode to protected mode.

And in this case those new protected modes have mitigated the problem.

This prevents programs running in protected mode from interfering with each other's memory.

Certain restrictions applied since these programs were executed in the processor's protected mode.
