	X86 - Wikipedia, the free encyclopedia
		The architecture is called x86 because the earliest processors in this family were identified by model numbers ending in the sequence "86": the 8086, the 80186, the 80286, the 386, and the 486.
		The x86 architecture first appeared inside the Intel 8086 CPU in 1978; the 8086 was a development of the 8008 processor (which itself followed the 4004).
		Starting an old program while Windows 3.0 was running in protected mode triggered a warning dialog, suggesting to either run Windows in real mode (it could presumably still use expanded memory, possibly emulated with EMM386 on 80386 machines, so it was not limited to 640KB) or to obtain an updated version from the vendor.

	Encyclopedia: X86 assembly programming in real mode
		All modern x86 operating systems use protected mode; however, when the computer boots, it starts up in real mode, so the part of the operating system responsible for switching into protected mode must operate in the real mode environment.
		In real mode, two registers are used for a memory address: one to hold the segment, and one to hold the offset.
		This program could be compiled into a DOS-compatible.com-file, it is also quite possible to assemble it to any other operating system running in realmode, or even no operating system at all, but you might need to make some minor changes in such cases.

	X86 assembly language - Wikipedia, the free encyclopedia
		The x86 processor and instruction set design is CISC; however, since the end of the 1990s the internal architecture moved towards being more of a RISC or VLIW design.
		The addressing modes were not drammatically changed from 32 bit mode, except that addressing was extended to 64 bits, physical addressing is now sign extended (so memory always adds equally to the top and bottom of memory; note that this does not affect linear or virtual addressing), and other selector details have been dramatically reduced.
		In real mode or 16-bit protected mode, a near jump uses a 16-bit or unsigned operand as an address relative to the current segment base; in 32-bit protected mode, a near jump is a 16-bit or 32-bit signed relative offset similar to a short jump.

		(Click link for more info and facts about Protected mode) Protected mode is the mode in which most modern ((computer science) software that controls the execution of computer programs and may provide various services) operating systems run their code.
		That means that inside protected mode, each address has to go through two layers of redirectioning before it gets through to the real memory.
		The memory layout for computers in protected mode is similar to that of real mode.

		x86 assembly programming in real mode involves the manipulation of several 16-bit processor registers, and dealing with physical addresses in memory only (as opposed to protected mode).
		The x86 architecture is an interrupt -driven architecture.

		There are mainly two different modes in which a x86 processor can work: real mode and protected mode.
		A typical software interrupt is (in real mode) interrupt 0x21 (the ISR that handles this interrupt gets the function number and all the parameters from the program and then it executes the selected DOS-function) and int3 (breakpoint, often used to enter some sort of software-debugger).
		Is the mode in which most modern operating systems run their code.

	x86 Assembly Language FAQ - General Part II
		In real mode, the value of the segment register is shifted left four bits to find the base address of the segment, and the size of the segment is always 64k.
		In protected mode, the value in the segment register is used as an index into a descriptor table located in memory, and the base address and size (which may be as small as 4 KB, or as large as 4 GB) from the descriptor table are loaded into the descriptor cache.
		After switching from protected mode to real mode, however, when you load the segment registers with their new values, the segment's base address is recalculated according to real mode rules, but the size limit is not changed.

		The IP register cannot be accessed by the programmer directly.
		Some of the flags that the FLAGS register contains is carry, overflow, zero and single step.
		In referring to an address with a segment and an offset, the notation of segment:offset is used, in the above example, the linear address 0xEB5CE can be written as 0xDEAD:0xCAFE, or if one has a segment and offset register pair, DS:DX.

	Embedded x86 Programming: Protected Mode
		The x86 is expected to seriously affect the embedded systems market for the following reasons: applications can be developed on a PC (not necessarily on a target), both 16-bit and 32-bit programming are fully supported, a complete diversity of hardware is available, and GUI features—through Windows CE and 95—will become more accessible.
		A logical address, as used by a program, is still the combination of a segment and a general register, or more precisely, a 16-bit selector and a 16-bit or 32-bit offset.
		It’s the current CPU mode (either real mode, 16-bit protected mode, or 32-bit protected mode) that indicates whether 16-bit or 32-bit operands and addresses are used and how they are used.

		Its not really portable to different sizes of int (the numbers 0x7f7f7f7f and 0x80808080 would have to be truncated or expanded, and casting p from a pointer to a scalar is not guaranteed to work) and its not any easier to understand than the assembly.
		Consider that what you really want is a mapping of 16 input bits that you just want placed in some output positions, where each input bit is independent from the other bits.
		The problem is that the address mode of x86 processors require 32 (or 16) bit registers, so some kind of byte -> dword (or word) conversion also happens.
