Minimal operating system written in Rust

Set up the environment

To set up the environment run the following commands:

   chmod +x ./install-deps.sh

   ./install-deps.sh

Build and Run

Build using rust-based bootloader

The runner is set up to compile, build and run the OS

To build run the following commands:

   cargo bootimage

and then,

   qemu-system-x86_64 -drive format=raw,file=target/x86_64-unknown-none/debug/bootimage-zer_os.bin

To build and run:

   cargo run

Build using custom bootloader

1. Add the following lines to your ./Cargo.toml

      [lib]
      path = "src/main.rs"
      crate-type = ["staticlib"]
   

2. Generate ISO using the following command

      cargo make generate_iso

3. Run:

      cargo make run

For debugging you could run

   cargo make dbg

and then in another terminal (make sure lldb is installed)

   lldb
   gdb-remote 1234
