Welcome to the scaraOS wiki!

ScaraOS is a 32bit mutiboot OS kernel for IA32 (PC/AT) systems. I wrote it to teach myself OS fundamentals and just to have a bit of fun. It already has PCI support, the beginnings of a paged memory management system, and the start of a VFS layer. It supports the basic PC/AT stuff such as timer, PIC, keyboard, floppy.

The most recent version includes a shedload of bugfixes as well as working pre-emptive multi-tasking and a system call interface. The only implemented system call so far is exit and exec. Implementations of fork, open, close, read, write are currently pending. You can grab a screenshot

The goals of scaraOS are not to reproduce POSIX or any other existing OS but to be a fun project for learning OS development. For this reason I am trying to avoid falling in to the trap of writing a bootloader with a lot of “drivers” and then calling it an “OS”. You can read the TODO list to get an idea of upcoming development. You will notice my priority is getting a functional userspace environment up and running rather than adding a lot of drivers. Also I haven’t mentioned what the userspace API is going to look like yet because I’m concentrating on getting things like Demand Loading, Page Cache and Context Switch implemented first.
