This is a simple os coded in batch and soon to be bootable via ms dos, be sure to test the pre-alpha version, NOW!! its called os.2 because i already coded version 1 and accidently delleted version 1, so i just called the next os.2, hope you like it!
I just would like to point out, that it is impossible to write an operating system in batch. To create a operating system, you have to use low-level programming languages, like assembler and C. You can`t boot up a .bat file, you have to have a boot loader. Creating a os isn`t such a simple task as you think.
