MOROS is a toy operating system written in Rust for the x86 architecture.
Implemented
- Hardware interrupts
- PS/2 Keyboard (qwerty and dvorak)
- VGA Text mode
- Paging
- Heap allocation
- RTC clock
- PCI enumeration
- ATA PIO mode
- Random number generator
- RTL8139 network card
- IP/TCP/UDP/DHCP/DNS/HTTP protocols
- Basic filesystem
- Basic shell
- Basic text editor
- Basic file and network commands
- A LOT OF SHORTCUTS TO GET EVERYTHING WORKING
- HERE BE DRAGONS
- Processes
- Multitasking
- A real userspace
Usage
Install tools:
curl https://sh.rustup.rs -sSf | sh
rustup install nightly
rustup default nightly
rustup component add rust-src
rustup component add llvm-tools-preview
cargo install cargo-xbuild bootimage
Create disk:
qemu-img create disk.img 128M
Run with:
cargo xrun --release -- \
-cpu phenom \
-rtc base=localtime \
-nic model=rtl8139 \
-hdc disk.img
Or with a serial console:
cargo xrun --release --no-default-features --features serial,dvorak -- \
-cpu phenom \
-rtc base=localtime \
-nic model=rtl8139 \
-serial stdio \
-display none \
-hdc disk.img
Or with cool-retro-term for a retro console look:
sh run/cool-retro-term.sh
