A simple operating system written entirely in assembly by the ITMO University students.

To build a bootable iso image, run:

make

You will need "grub2" to be installed with support of the multiboot kernels. Also may need to install the "xorriso" utility (or the "libisoburn" package if your distro repos do not contain xorriso).

If you prefer qemu, use (make will build kernel if not already):

make run

if you prefer bochs, use:

make EMUL=bochs run

You can redefine almost all settings for the building and running process. For example if you want to select the version of grub-mkrescue utility there are two ways to do this, first:

make GRUB_MKRESCUE=grub2-mkrescue all

or create file named "Makefile.local" and set the variable there:

GRUB_MKRESCUE = grub2-mkrescue

Above is true for many other variables, for example "EMUL", "SUBMODULES", "OUTPUT_DIR" etc.

Q: I have "xorriso : FAILURE : Cannot find path '/efi.img' in loaded ISO image" message when trying to run "make run"

A: Probably you have ArchLinux and it have some strange problems with it. Create file "Makefile.local" and add "GRUB_MKRESCUE = grub-mkrescue -d /usr/lib/grub/i386-pc" line to it.
