RadiumOS

General Information

⚠ Secure warning.
To secure RadiumOS, you must modify the source code or make RSH runtime scripts.

RadiumOS (formerly TomatoOS) is a 32-bit OS, similar to a former project, NyaOS, developed however completely from scratch. Test this OS in a virtual machine!

RadiumOS uses the x86 inb and outb instructions for direct hardware communication. These instructions allow the kernel to read and write bytes to hardware ports, enabling low‑level device control.

How to Run

⚠ QEMU recommended.
Download from qemu.org. VirtualBox and VMware have been tested and works on Windows machines, but QEMU is the most reliable, stable, and recommended option.

Download RadiumOS.iso and run:

Bash
