####A self-make operating system with the book called 30 days to build OS ourselves

####Giving us a way to make our own OS within this book, I also push tools given by the author so you can run it directly using bat files in directory KanbOS

####I will push some new attributes after finishing reading this book. This res just a copy of my codes

##How to run

  1. Clone those source code above first.
  2. cd to the KanbOS directory in tolset folder.
  3. Open !cons_nt.bat file to run console.
  4. Input make run and wait a moment.

##Log

Update 1st day: complete build an easy 'OS' called helloos using machine code

Update 2nd day: try to rebuild the helloos within an more readable 8086 assembly lang, also learn to use makefile to compile the codes.

Update 3rd day: this time we make a real IPL to boot our OS from disk.

  • The first demo is about the way to boot program from disk using INT 0x13
  • The second demo is about how to handle error when reading disk
  • The third demo is about to read until 18th section. All contents will be put into 0x8200 to 0xa3ff
  • Now we reach the fourth demo, which still load data on the disk. This time we try to load until 10 cylinders both sides. I add some messages to tell us whether loaded successfully
  • This demo add another .nas file which exactly is the real OS. We just load it into DRAM but not run it.
  • We are going to the sixth demo, which contain a real OS this time. The sys file call a graphic BIOS INT to show a total black display
  • The last demo here, containing naskfunc.nas file as to complete HLT function adding to bootpack.c.
  • This demo is the one which add the first .c file to complete the OS. Also chage into 32bit mode.
  • The last demo here, contain naskfunc.nas file to provide a HLT function adding to bootpack.c.

Update 4th day: about how to use Clang and draw something onto our monitor.

  • The first demo here. At the beginning of the forth day, I draw a purple display to our monitor.
  • Now pointer is appeared! Finally we can use pointer to show our graphs:)
  • OK we've already move a step forward. This time is palette. Color defined by ourselves.
  • Now, here we have three filled boxes. First try to draw some graphs in our OS:)
  • Toolbar!!! A little bit excited.

Update 5th day: put charactor on the screen, then draw mouse pointer. -First demo this day is about how to use pointer to get information of screen. -Second demo is about using struct to store data of screen. -Coming to the third demo, this one is the one which achieves putting charactor A. -Forth demo is a development of the third one, which puts a string 'ABC123'.
