/64Bit-Kernel

A step to build an OS someday :)

Primary LanguageAssembly

64Bit-Kernel

Designed a kernel for a 64-bit OS

Right now it just prints a single Hardcoded string "64 Bit KERNEL --Yeshasvi" (Even this required Lots of work)

PreRequisites

  • Any Code editor (I used VsCode)
  • Docker for building environment
  • Qemu for emulation purpose (add it to path)

Setup

Build env using Docker

  • docker build buildenv -t myos-buildenv // -t is used for giving tag and myos-buildenv is your tag

  • To enter into buildenv

    • Windows cmd: docker run --rm -it -v "%cd%":/root/env myos-buildenv
    • Windows powershell: docker run --rm -it -v "${pwd}:/root/env" myos-buildenv

  • Now to get iso and other output files run make file as: make build-x86_64

  • Now exit to leave buildenv

Emulate

As mentioned before, use Qemu for emulation

  • Run: qemu-system-x86_64 -cdrom dist/x86_64/kernel.iso

That's it for now :)
