babyOS

A small #![no_std] x86 (i386) kernel written in Rust. It boots via GRUB (multiboot), and runs under QEMU.

Requirements

• Docker
• Qemu (qemu-system-i386 command)

Quick start

make # Builds the iso, then runs Qemu

Layout

• src/kernel.rs — kernel entry point (_entrypoint) and test runner
• src/lib.rs — baby_lib: panic handler and module wiring
• src/memory/ — physical/virtual memory initialization and management
• src/io/ — VGA text buffer and serial driver
• src/interrupts/ — IDT and exception handlers
• tools/build/ — boot stubs, linker script, target spec, GRUB config
