DELOS 2.0

DELOS 2.0 is an educational project developed by students within the KIV/OS module at the University of West Bohemia. Its main purpose is to demonstrate basic functionality and techniques used when developing an operating system. The operating system runs in a 32-bit protected mode on a x86 processor.

How to run it?

Dependencies

In onder to successfully compile the kernel, you need to have the following tools installed on your system: g++, ld, nasm, make, xxd, and genisoimage.

The compilation process is done through the make command that is supposed to be executed in the root folder of the project structure. Upon successful compilation, DELOS-2.0.iso will be generated. This file represents and iso image of the operating system that can be run in VirtualBox or Qemu.
