MyOS - DIY Your Own Operating System

In the meanwhile of exploring security and privacy issues and solutions in IoT field, I feel stronger and stronger that I need some knowledge about how an Operating System works. Even though I have taken the Operating System course during my undergraduate, many details about the underline working process are still blind to me. This time, I would like to follow several online famous tutorials and make a day-by-day learning progress board with details.

Give credits to :

• “Makeup An OS In 30 Days” Hidemi Kawai - This book is not easy to find, but the author, Hidemi Kawai, is famous for his project on building OSASK system.

The working environment is:

• building environment: MAC OSX

• assembly compiler: nasm

• c/c++ compiler/linker: i386-elf-gcc & i386-elf-g++

• project running platform: x86_64

• VM: qemu

Progress:

• Day 00 - Environment Preparation
