ShinOS

ShinOs is a toy operating system project built to learn how computers boot and hwo a kernel starts running.

Current Goal

The current goal is to understand system project built to learn how computers boot and how a kernel starts running.

• firmware starts the machine
• GRUB loads the kernel
• the kernel begins executing in QEMU

Project Layout

• src/boot.s - minimal assembly entry code
• src/kernel.c - first C code executed by the kernel
• grub/grub.cfg - GRUB boot configuration
• linker.ld - linker layout for the kernel binary
• Makefile - build and run commands
• BOOT.md - notes about the boot process

Current Scope

This phase only covers booting ShinOS through GRUB in QEMU. It does not include memory management, keyboard input , drivers , or a shell.
