• A personal software project designed to run on x86_64 systems.
• This is just for fun, so don't expect anything usable for a while.
• See Lemon for reasons I shouldn't be doing this.

FreeLSD currently has the following features implemented in the 64-bit branch:

• Support for Multiboot2, SSP and VESA graphics.
• Virtual and physical memory management.
• APIC-driven or PIC-driven interrupts.
• Support for SMP using ACPI <1.0.
• And of course, the FreeLSD frog!

Tested on QEMU, VMWare, Bochs and on bare-metal using my laptop. VirtualBox doesn't support huge pages when booting x86_64 systems unfortunately.

Install clang and nasm using your package manager of choice. Execute sudo make disk to create an empty disk with the correct partition layout for FreeLSD.

I couldn't get createdisk.sh to work on macOS, so if you're trying to build FreeLSD on macOS then you'll have to run this script on an external machine and copy the disk image over to your own machine.

Invoke the Makefile using sudo make. Use the -jN flag to speed up compilation (N being the number of cores in your system). This will compile the kernel and copy it to disk before launching QEMU.

The Makefile requires root on Linux because of losetup. If you're building on macOS, sudo is not required.
