Comprehensive Analysis of pmtest1.asm-[orange's] in "writing an operating system by yourself" I recently learned how to write the OS. I have seen a strong post on the Internet. I don't know how to write this code.Segment mechanism for easy

The operand of the assembly instruction can be the data in the memory. Addressing the memory is how to make the program obtain the required data correctly from the memory. Intel's CPU can work in two addressing modes: real mode and protection mode.

1.For example # DEFINE _ Library __There is nothing behind it. What's the use ???Observe the File Include/unistd. h and you will see # ifdef _ Library __2.The fork () function generates a new process.The new process should also start from the

This article is the 12th chapter of the original book study notes.Say a digression, this post is to write, because let me mistakenly deleted, abominable is csdn in the Recycle Bin can not find! Well, then write it again, I have a strong will. Sima

Under Linux there is a directory, the/usr/src/kernels/directory, the following is a Linux system kernel file,For example: 2.6.18-164.el5-x86_64, 2.6.18-8.el5-x86_64, and 2.6.18-194.el5-x86_64, what do these file numbers mean? For example, what does 2

The operands of the assembly instruction can be in-memory data, and how to get the program to correctly obtain the required data from memory is the addressing of memory. INTEL's CPUs can work in two addressing modes: Real mode and protected mode.

  Organize from the Internet Eax, EBX, ECx, EDX, ESI, EDI, EBP, ESP, etc. are the names of General registers on the CPU in x86 assembly language, and are 32-bit registers. These registers can be viewed as variables in C language. For example: Add
