NaOS v0.2.0 — in development

01/

Highlights

40 plain-English commands

Files, system, network, power — with history, scrollback, font sizes, output redirect and a themeable prompt.

AHCI · NVMe · ATA + FAT32 + live RAM copy

One block layer, writable FAT32, long filenames. Boots from SATA, NVMe — or straight off the ISO with files.

fork() with CoW

Ring-3 programs, private address spaces, preemptive scheduler, copy-on-write fork, file syscalls.

TCP server + client

E1000 + virtio-net drivers, ARP/ping, UDP sockets, DHCP lease at boot, DNS — TCP server (serve-file, one file per call) plus the TCP client with HTTP get-page and hash-verified system-update.

PS/2 + USB HID

Polled XHCI stack with hotplug rescan, classic PS/2 fallback, PC-speaker beeps.

ISO export + auto-boot

El Torito UEFI image, shell auto-boot fallback, Rufus/DD-mode guide for real hardware.

Verified requirements

Tool	Version	Purpose
QEMU + OVMF	11.1.0	emulator + UEFI firmware
x86_64-elf-gcc + ld	16.2.0 / 2.47	kernel (via /opt/cross)
x86_64-w64-mingw32-gcc	16.2.0	bootloader (PE+)
NASM · Make · mtools · Python	3.02 · 4.4.1 · 4.0.49 · 3.14.8	stubs · build · FAT image · font + scripts

Honest limits: TCP serve handles one connection per call (3-deep SYN backlog) · NVMe needs 512B namespaces (polled, no MSI-X/4K yet) · NaOS-FS: 128KB images max, new files 8.3-only · CD/USB boot is a live RAM session (files work, writes vanish on reboot; give the VM ≥256MB) · UEFI-only, Secure Boot off.
