tjOS

Proof of concept for MacBookPro15,4

A bootable image showing keyboard input and graphics.

Includes a QEMU setup to run it virtually as well.

Building

git clone --depth 1 https://github.com/tjcaul/tjOS
cd tjOS/
cp qemu/OVMF_VARS-pure-efi.fd.default qemu/OVMF_VARS-pure-efi.fd
tools/compiler/build.sh
tools/compiler/clean.sh
tools/mkfont/build.sh
scripts/compile.sh

Installing

scripts/install.sh /dev/diskx

Running in QEMU

scripts/mkhd.sh
scripts/qemu.sh

Scripts

compile.sh: compile files in src/ to an executable (build/BOOTX64.EFI)

install.sh: copy BOOTX64.EFI to a drive

mkhd.sh: build a virtual drive for QEMU and install tjOS on it

qemu.sh: boot the virtual drive in QEMU

Run scripts/qemu.sh shell to boot to UEFI shell instead for troubleshooting.
