原文 Assembler / なぜx86ではMBRが"0x7C00"にロードされるのか？(完全版)

感謝 descent 大大分享本文，隨便看隨便譯。本文不是逐句譯，同時也不是這方面的專家 (不管是語言或技術)，用語不一或缺漏錯誤在所難免，歡迎自行 fork 修正指教

誰適合看本文?

對 x86 架構與組合語言有基礎認識，以及從 MBR 到載入 OS 這一段過程有興趣的人 (還有談到中斷向量或 INT xxx 時不會一臉茫然的人)

Motivation

As for now (mid 2016), there doesn't seem to be a C/C++ package manager that stands out of the crowd. To understand the reasons behind this failure, I will try to list in this README most C/C++ package managers, highlight differences between them, then list critics that are made about them.

Note: this README is merely a gathering of personnal notes, doesn't intend to be a reference in any way.

A standard proposal : http://open-std.org/JTC1/SC22/WG21/docs/papers/2016/p0235r0.pdf

Indentation sensitive parser combinators

An indentation sensitive parser combinator language is one that helps you express ideas like "this parse only succeeds if it's within the current indentation block". The concept is somewhat small and elegant and is implemented in a few libraries. In this writeup, I will use examples from indents.

Background and goal

The direct goal will be to write the sameOrIndented parser combinator with a type
