Protected Mode.
The size of memory in Protected mode is usually limited to 4 GB.
Protected mode can be either paged or unpaged.
This mode is exclusively available for the 32-bit version of protected mode;
It offers a protected mode to keep the opened materials safe.
It does not exist in the 16-bit version of protected mode, or in long mode. .
X86 processors that support protected mode boot into real mode for backward compatibility with the older 8086 class of processors.
There is also a sub-mode of operation in 32-bit protected mode, called virtual 8086 mode. .
An OS that is aware of SSE will activate Enhanced mode, whereas an unaware OS will only enter into traditional Protected mode.
The mode used by 16-bit('protected mode' or'real mode') and 32-bit operating systems.
Like 80286, the 80386 supports two different operating modes: Real and protected mode.
Legacy mode is the mode used by 16-bit("protected mode" or"real mode") and 32-bit operating systems.
Since the basic instruction set is the same,there is almost no performance penalty for executing protected mode x86 code.
This allows for a great deal of flexibility in running both protected mode programs and real mode programs simultaneously.
Physical Address Extension or PAE was first added in the Intel Pentium Pro,to allow an additional 4 bits of physical addressing in 32-bit protected mode.
TMT Pascal the first Borland-compatible compiler for 32-bit DOS protected mode, OS/2 and Win32 operating systems.
System calls often use a special machine code instruction which causes the processor to change mode(e.g. to"supervisor mode" or"protected mode").
To access the extended functionality of the 80286, the operating system would set the processor into protected mode, enabling 24-bit addressing and thus 224 bytes of memory(16 megabytes).
In protected mode, a segment register no longer contains the physical address of the beginning of a segment, but contain a"selector" that points to a system-level structure called a segment descriptor.
Virtual 8086 mode does not exist in the 16-bit version of protected mode, or in long mode. .
Virtual memory was introduced to the x86 architecture with the protected mode of the Intel 80286 processor, but its segment swapping technique scaled poorly to larger segment sizes.
On May 22, Microsoft launched Windows 3.0, featuring streamlined user interface graphics and improved protected mode capability for the Intel 386 processor.
So Intel created a slightly modified version of Protected mode, called Enhanced mode which enables the usage of SSE instructions, whereas they stay disabled in regular Protected mode.
Virtual 8086 mode does not exist previously in the 16-bit version of Protected mode, or in the 64-bit long mode. .
In protected mode, the segment selector can be broken down into three parts: a 13-bit index, a Table Indicator bit that determines whether the entry is in the GDT or LDT and a 2-bit Requested Privilege Level; see x86 memory segmentation.
Operating system boot code, which might be stored in ROM,may place the processor into the protected mode to enable paging and other features.
MS Windows NT, Linux, and other protected mode operating systems in general ignore the abstraction layer provided by the BIOS and do not use it after loading, instead accessing the hardware components directly.
This is basically a special hybrid operating mode which allowed old DOS programs andoperating systems to run while under the control of a Protected mode supervisor operating system.
In addition to real mode, the Intel 80286 supports protected mode, expanding addressable physical memory to 16 MB and addressable virtual memory to 1 GB, and providing protected memory, which prevents programs from corrupting one another.
This is basically a special hybrid operating mode that allows real mode programs andoperating systems to run while under the control of a protected mode supervisor operating system.
