Limine

What is Limine?

Limine (pronounced as demonstrated here) is a modern, advanced, portable, multiprotocol bootloader and boot manager, also used as the reference implementation for the Limine boot protocol.

If your filesystem isn't listed here, please read the philosophy first, especially before opening issues or pull requests related to this.

Minimum system requirements

For 32-bit x86 systems, support is only ensured starting with those with Pentium Pro (i686) class CPUs.

All x86-64, aarch64, riscv64 and loongarch64 (UEFI) systems are supported.

Packaging status

All Limine releases since 7.x use Semantic Versioning for their naming.

Binary releases

For convenience, for point releases, binaries are distributed. These binaries are shipped in the -binary branches and tags of this repository (see branches and tags).

For example, to clone the latest binary release of the 8.x branch, one can do:

git clone https://github.com/limine-bootloader/limine.git --branch=v8.x-binary --depth=1

or, to clone a specific binary point release (for example 8.5.0):

git clone https://github.com/limine-bootloader/limine.git --branch=v8.5.0-binary --depth=1

In order to rebuild host utilities like limine, simply run make in the binary release directory.

Host utility binaries are provided for Windows.

Building the bootloader

The following steps are not necessary if cloning a binary release. If so, skip to "Installing Limine binaries".

Prerequisites

In order to build Limine, the following programs have to be installed: common UNIX tools (also known as coreutils), GNU make, grep, sed, find, awk, gzip, nasm, mtools (optional, necessary to build limine-uefi-cd.bin). Furthermore, gcc or llvm/clang must also be installed, alongside the respective binutils.

Configure

If using a release tarball (recommended, see https://github.com/limine-bootloader/limine/releases), run ./configure directly.

If checking out from the repository, run ./bootstrap first in order to download the necessary dependencies and generate the configure script (GNU autoconf required).

./configure takes arguments and environment variables; for more information on these, run ./configure --help.

./configure by default does not build any Limine port. Make sure to read the output of ./configure --help and enable any or all ports!

Limine supports both in-tree and out-of-tree builds. Simply run the configure script from the directory you wish to execute the build in. The following make commands are supposed to be run inside the build directory.

Building Limine

To build Limine, run:

make    # (or gmake where applicable)

Installing Limine

This step will install Limine files to share, include, and bin directories in the specified prefix (default is /usr/local, see ./configure --help, or the PREFIX variable if installing from a binary release).

To install Limine, run:

make install    # (or gmake where applicable)

Usage

See USAGE.md.

Limine uses a stripped-down version of tinf for GZIP decompression in early x86 BIOS stages.

Limine uses stb_image for wallpaper image loading.

Limine uses libfdt for manipulating FDTs.
