[Here](http://wiki.osdev.org/GCC_Cross-Compiler) you'll find some directions\n\nTo compile it, just type\n\n```\n$ make\n```\n\nThe makefile assumes your cross-compiler folder is in the PATH.\nOut-of-tree builds aren't tested.\n\nYou can also type ```make iso``` to create an ISO with the system or ```make qemu``` to launch it on QEMU.\n\n## Minimal Requirements\n - A P6-level processor\n - 2 MiB of RAM\n\n## ToDo list\n\nIf you want, you can help me with these tasks\n\n- [X] Jump to usermode and run some basic code\n- [X] Improve VFS and create filesystem drivers, like\n  - [X] a FAT driver\n  - [ ] a ext driver\n- [ ] Add virtual 8086 support\n- [ ] Add VBE support (for creating framebuffers in BIOS systems)  \n- [ ] Add DMA support in ATA driver\n- [X] Add an ELF parser\n  - [ ] Launch ELF code in usermode\n- [ ] Create some syscalls\n- [ ] Support x86-64\n- [ ] Support UEFI\n  - [ ] Add GOP framebuffer support (framebuffers in UEFI)\n- [ ] Support, at least, one ARM board, like\n  - [ ] Integrator/CP\n  - [ ] Beaglebone\n  - [ ] Raspberry PI\n- [ ] Add SATA disk support\n- [ ] Add networking\n- [ ] Add USB support\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Farthurmco%2Frainos","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Farthurmco%2Frainos","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Farthurmco%2Frainos/lists"}
