Rusty OS (T-OS 3.0)

A modern, bare-metal desktop operating system written from scratch in pure Rust for x86_64 architecture.

Is this a Linux distribution or a Windows mod?
No. Rusty OS runs its own custom no_std kernel written from scratch. It does not share source code or binaries with Linux, Windows, or any existing operating system kernel.

Türkçe Açıklama

Rusty OS (T-OS 3.0), x86_64 mimarisi için sıfırdan Rust dili ile geliştirilmiş no_std bir masaüstü işletim sistemidir.

Kendi UEFI önyükleyicisi üzerinden açılır; bellek yönetimi, donanım sürücüleri (NVMe, xHCI, Intel HDA), FAT32 dosya sistemi, SYSCALL/SYSRET tabanlı ring-3 süreç yönetimi ve Windows 7 ilhamlı Aero masaüstü ortamını tamamen bare-metal seviyesinde ayağa kaldırır.

Ayrıca, mevcut işletim sistemlerine zarar vermeden sistemi gerçek GPT disklere kurabilen RPE (Rusty Preinstallation Environment) ortamına sahiptir.
