=========

This repository provides a disassembly of the Windows XP Master Boot Record.

The whole code has been disassembled by ndisasm, and then recreated in nasm

syntax. Exhaustive comments have been added in order to help with anybody who

might want to look a bit more into the boot process of this OS.

Assembling the code provided here gives the same code as the original image,

saving for occasional differences in opcode encodings that have no significance

whatsoever.

Only the MBR (e.g. the first sector of the boot disk) has been analyzed so far.

Analysis and disassembly of the active partition's first sector (which contains

the next stage of the bootloader, and is loaded by the MBR code) will appear

here sometime in the future.
