you've been warned :-)\n\nThe idea behind IFEM is having an operating system where\n\n  - kernel is a minimal and thin piece of functionality\n  - modules and drivers don't know anything about each other beyond APIs and\n    SPIs\n  - and there are no dependencies during compile and link time - instead pieces\n    fit together only at run-time.\n\n# Current Status\n\nVersion 0.0.1 is the first release where \"something works\":\n\n  - bootloader loads the OS from the disk (image) into memory and hands the\n    control over to kernel.\n  - kernel\n    * does basic hardware init routine\n    * enables the protected mode\n    * sets up two interrupt handlers (timer and keyboard)\n  - interrupt handlers print the key-code on each keyboard interrupt and\n    announce a message every 200 timer ticks.\n\nHere's a recording of its execution:\n\n\u003ca href=\"https://imgur.com/HcDL4vP\"\u003e\u003cimg src=\"https://i.imgur.com/HcDL4vP.gif\" title=\"source: imgur.com\" /\u003e\u003c/a\u003e\n\n# How To Build\n\n### Using Gnu toolchain on a Linux box\n\nProvided you have installed `gcc` (5+)  and `gcc-multilib` (if on a x64 machine):\n\n```\nmake clean all\n```\n\n### No Gnu toolchain\n\nProvided you have docker already installed:\n\n```\n$ docker run --rm -v $(pwd):/src -w /src -it gcc:9\n# make clean all\n```\n\n# How To Run\n\nIFEM's \"runnable\" binary is `ifem-os.img` which you can find in the root of the\nsource tree after a successful build.\n\n### [Bochs](http://bochs.sourceforge.net/)\n\nThere's a `bochsrc` file included in the source tree - provided you fix the paths\nin that file to match your own Bochs installation, simply run bochs while inside\nthe source tree.\n\n### Virtualbox\n\nIf you intend to run IFEM inside a vbox machine, you just need to boot your\nvm from `ifem-os.img` as a floppy disk image.\n\n### Physical machine\n\nIf you still have access to a machine with floppy drive, just write IFEM's\nbinary to the floppy (e.g. `dd`) and boot your machine!\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbahmanm%2Fifem-os","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbahmanm%2Fifem-os","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbahmanm%2Fifem-os/lists"}
