# bootloader-experiments
This repository contains a collection of bootloaders written by me in Assembly, for learning more about BIOS, bootloaders, and the Assembly language itself.
## Building
For building stuff, you will need an assembler, such as NASM. Optionally, you can also install `make` and `qemu` for easier building and running.
### The `Makefile` way
If you just want to quickly check out a bootloader, you can use `make` to build and run it. For example, to build the `hello_world.asm` code, simply run:
```bash
make hello_world.asm
```
That will build the bootloader with NASM and run it in QEMU.
If you want to build all of the files in the `src` directory, you can run `make` or `make all`.
### The manual way
If you want to build a bootloader manually, do it the way your assembler does it. With NASM, you can build the `hello_world.asm` file by executing:
```bash
nasm -f bin -o bootloader.bin src/hello_world.asm
```
Then, you can run it in QEMU by putting the command below in your terminal:
```bash
qemu-system-x86_64 -drive format=raw,file=bootloader.bin
```

## Contributions
If you see any errors within the code or in the README itself, feel free to open an issue. Since this is a repository for my personal learning, I'm not looking for any pull requests adding new code, but I'm always open to suggestions and corrections.
