However this is in its very early stage and is using some -boilerplates from the lecture e.g. the startup assembly code. - -This project will adapt GPL when the dependencies are sorted out (hopefully very -soon). Untill then all rights are reserverd. - -# The rust port of OOStuBS [WIP] - -This is a toy bare metal operation system implemented in Rust. Apologies for my -shitty code, I'm a rust beginner. - -The project is based on the OOStuBS, an OS exercise project used in some German -Universities. This one in perticular, is based on the TU Dresden version -(Operating System Construction), led by my Professor Dr. Horst Schirmeier. - -**Status / Roadmap** -[X] - Basic code structure -[X] - Build minimal iso image -[X] - bootable using grub -[X] - Setting up CGA display, print something (hello world) -[X] - Provide "printf" support -[X] - Intigrate print into rust println! etc. -[.] - asm!
