Can you write a computer operating system in half a month?

1Can you write a general graduation system in half a month? There is the following explanation for this problem: as long as the level is sufficient, it is still very simple to write a micro-corenel that only runs on a specific platform and only thread scheduling in two weeks.

2. In fact, it is not difficult to develop an operating system. A few people can do it for a few months. One person developed a system in assembly language, 44M size, with mp3 playback, picture viewing,. The operating system is available, and the most important thing is its ecosystem, operating system driver, software and compiler.

3. OK. Generally, you will have such ability after graduating from the computer department as a bachelor's degree. You need some assembly knowledge, computer principles, operating system principles, C and C knowledge, and data structure knowledge. This is enough for you to write a small system by yourself.

4. Take the server system as an example, server200server200server2012. Generally, a new system will not be released until a few years later. So you are a task that is basically impossible for a programmer to write a computer operating system. It takes years of hard work of a team to write it down.

How to make a GHOST system, add some software you want in it

First, go to the next GHOST11, which is relatively new at present. The GHOST version, then go to the next "waste customer DOS toolbox" and install it, so that you canEnter the DOS directory by booting, then enter the directory of your GHOST, run GHOST, make a mirror file of your system disk, and save it in other directories.

First of all, you must have a software that can be used to encapsulate the system. At present, there are a lot of packaging software, and the free ones are basically forced to promote their own promotion software. Therefore, when you encapsulate, you must clean up some promotion software during the encapsulation process. This cleaning process is very troublesome and may not be able to clean up.

Get ready to work. Install Windows XP and use Windows Update to upgrade the latest system patches (including service Pack l and other latest Hot fix).

When you start learning, first extract the EZBOOT directory in other CDs (I have made changes to the file extracted from Tomato GHOST6 for your reference) and then delete T_BACK.B15 T_BACK.BM2 T_LOGO.B15 T_LOGO.BM2 THESE FOUR FILES.

I) OS Description In the future, I will start to toss the operating system and have a little motivation.

Step 1: Write an assembly program (Linux version) Under Linux, I use two programs, as86 and ld86, to generate code. ( I take the Ubuntu distribution of Linux as an example here). As86 is simple enough for our task, so it is also more suitable for us.
