NULLos has its own website: nullos.de. That's where you get the images – and these docs.

Everything is at nullos.de/#download, the docs at nullos.de/doku/.

Which file for what?

FileFor
nullos-0.3-x86_64.imgUSB stick, hard disk, SSD. GPT with EFI partition (FAT32), at least 64 MiB.
nullos-0.3-x86_64.isoLive CD/DVD or virtual machine. Also fits on a USB stick.
SHA256SUMSChecksums for both
ESP32 firmwarefor the ESP32-C5 coming soon

The version number is always in the name (it comes from the kernel, currently 0.3). On the website they're at nullos.de/download/nullos-<version>-x86_64.img (and .iso, SHA256SUMS).

Everything is inside: bootloader, kernel and a RAM file system with the shell and a good 400 tools. Runs only on PCs with UEFI (x86_64) – old BIOS machines won't start it. So far the images have only been started in QEMU, not yet on a real PC. coming soon

If every file says OK or ok: all good. Otherwise download again.
