project_c0rry is the bootloader of the attempt to create a Minimalistic Operating System, including and a yet to be named Kernel, with a yet to be named Text(perhaps somewhere down the line even Graphical) User Environment.
Booting on a BIOS System(technically also UEFI System as long as it still supports BIOS), switching into Protected Mode(32-bit Mode) and/or Long Mode(64-bit Mode), depending on what Architechture you would install the Bootloader as, load and start a Kernel written in C/C++
UEFI is coming soon ish(trademark)
You will need a x86_64-elf compatible or i386-elf compatible cross-toolchain! You can change the default prefix (x86_64-elf- for x86_64 and i386-elf- for i386) by either export CP=<newprefix> or CP=<newprefix> make. Same goes for the compiler with export CC=<othercompiler> or CC=<othercompiler> make
Clang has not been tested to work yet!
Simply change the working directory to src in the Terminal and execute make then make qemu for your own safety.
In case you would want to use a different emulator like bochs, add boot.flp, that will appear within "src/" after running make, as a Floppy and set it up to Boot from it. Also make sure the Emulator is Legacy BIOS compatible, as this Project isn't UEFI, yet
src/ contains the source code and Makefile
x86_64/ or i386/ contain the code for the 64-bit and 32-bit versions of the BIOS Bootloader
extra/ some code that is useful but hidden; should probably rename it at some point
real/ real mode specific code
protected/ protected mode specific code
long/ long mode specific code
