Download & Release Status
There is no public xHunOS image yet. This page tracks exactly what the first release will contain, the hardware it will target and the ways you will be able to boot it.
The kernel, xLang toolchain and DaoFS are under active development. No ISO, installer or beta channel is public. When a build is ready, it will be announced here and on the hardware page.
Please do not use unofficial builds
There are no mirrored images, torrents or third-party installers. A system that runs everything at Ring 0 should only be booted from a source you trust.
What the first public release will include
Bootable xHunOS image
A self-contained system image with the Ring-0 kernel, 640×480 window manager and core tools.
xLang shell and compiler
The interactive REPL that compiles source to native machine code in memory, with the standard library and ZAsm layer.
DaoFS storage tools
Formatting and inspection utilities for contiguous 2048-byte sector volumes.
Native application suite
Divination, BaZi ephemeris, breath pacing, guqin synthesis and the DolDoc journal.
Technical documentation
The architecture whitepaper and xLang specification in offline-readable form.
Verification, recovery and export tooling
An offline signature verifier, a read-only recovery mode for damaged DaoFS volumes, and a documented export path to plain files. These are release gates, not yet implemented.

Execution Vessels
QEMU RV64 (Simulation)
Emulate the custom 64-bit RISC-V environment inside standard QEMU (`qemu-system-riscv64 -M virt -cpu rv64`).
FPGA Development Board
Synthesize the custom RV64 soft-core on Xilinx / Gowin FPGAs with SPI screen and flash.
Tianming Box (Hardware Vessel)
The custom physical device: solid wood chassis, dedicated 300 MHz RV64 ASIC, and hardware entropy sensors.
Release FAQ
When will xHunOS be released?+
No date is announced. The kernel is at v0.2 and status updates are published as work completes rather than as deadlines.
Will there be a cloud or mobile version?+
No. xHunOS is designed for local, air-gapped hardware; a hosted or mobile port would contradict the architecture.
Can I build it from source?+
Source distribution has not been announced yet. Build instructions will be published with the first public release.
What happens if power is lost during a write?+
DaoFS is contiguous and simple, but crash consistency is still an open requirement. Compaction rewrites live extents, so an interrupted compaction can leave a volume inconsistent. Until atomic commit and a repair path are implemented and tested against injected power loss, treat the system as not crash-safe and keep backups.
Learn the architecture first
The whitepaper and the xLang specification describe the system in detail, including the parts that are still under construction.
