I'll likely be working on it on and off, and only updating the branch after major steps forward. +IndigoOS (name likely to change) will be a unix-like operating system for x86-64 computers. I'm hoping to impliment many things a modern operating system would have, including a desktop enviornment, pre-emptive multithreading, ASLR, and memory protection. I'd also like to port games such as DOOM. -##Questions and answers -### Why are you already parsing APCI tables? -When I first started this project, it was intended to be a bare metal mandelbrotset, then an operating system. This way I could set up an enviornment and become comftorable with the x86 architecture. I was going to have a pretty simple multi-core SMP setup to acheive a higher speed. However, as I worked more and more, I realized that this plan was counter productive. The main reason for this is that I'd be doing a lot of "static" work (for lack of a better word). It would be too hard to modify an existing project into an operating system, due to all the code I'd need to discard. +This project is in it's infancy. However, I'm making quick progress. I'll only commit major changes to keep the commit history clean. -### Will you support UEFI? -Maybe some day.
