fxOS is a hobby operating system written in Rust by Ansh Tyagi.
It targets computers with a x86-64 architecture and a BIOS, so mostly from 2005 to 2020, but it also runs well on most emulators (Bochs, QEMU, and VirtualBox).
This project started from the the second edition of Writing an OS in Rust by Philipp Oppermann and by reading the OSDev wiki along with many open source kernels.
make setupBuild the image to disk.img:
$ make image output=video keyboard=qwerty
Run fxOS in QEMU:
$ make qemu output=video nic=rtl8139
fxOS will open a console in diskless mode after boot if no filesystem is detected. The following command will setup the filesystem on a hard drive, allowing you to exit the diskless mode and log in as a normal user:
> install
Be careful not to overwrite the hard drive of your OS when using dd inside
your OS, and install or disk format inside fxOS if you don't use an
emulator.
Run the test suite in QEMU:
$ make test
