It designed as a really basic x86 operating system.\n\n## Features\n\nI am adding features as I have time and I learn more! Right now I am working on \u003cem\u003e[the bootloader](https://github.com/DAlba-sudo/cosa/blob/main/bootblock/boot.S)\u003c/em\u003e. \n\n```asm\nThe bootloader\n```\n\n### Supported Boot Methods:\n\n- [x] Legacy BIOS w/ Master Boot Record\n- [ ] UEFI\n- [ ] GRUB\n\n### In-Progress Misc. Boot Features:\n \n- [ ] Sets up initial GDT, LDT.\n- [ ] Transition to 32bit Protected Mode\n- [ ] Enter second-stage bootloader \n\n\u003cbr\u003e\n\n```\nThe Kernel\n```\nAhhh the kernel! Believe it or not, I am actually not as interested in the kernel just yet. Don't get me wrong, I'm looking forward to that part - but something about the bootloader just calls to me. I'll fill this out once I get to the kernel part!!\n\n\u003e Thanks for reading!\n\u003e - Diego Alba\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdalba-sudo%2Fcosa","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdalba-sudo%2Fcosa","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdalba-sudo%2Fcosa/lists"}
