Download Zeos
Zeos Alpha 0.2. It boots on x86-64 UEFI, draws a desktop, runs Z+ programs, and speaks HTTPS. It's real, and it's early.

How to get Zeos
Sign in at GritBoxOPS
Create or sign in to your GritBoxOPS account. That account is what unlocks the Zeos alpha image.
Grab the image
Download the current Zeos Alpha 0.2 image from your GritBoxOPS account. It's a single UEFI-bootable disk image.
Write it and boot
Write the image to a USB stick and boot a UEFI machine from it — or run it in QEMU. Steps below.
Boot from USB
The download is a raw disk image. Write it byte-for-byte to a USB stick with dd, then boot the machine with UEFI enabled and pick the USB device from the firmware boot menu.
Replace /dev/sdX with your USB device (double-check it — dd overwrites the whole disk). Reboot, enter your firmware boot menu, and select the USB stick. Legacy BIOS boot is not supported — UEFI only.
Or run it in QEMU
No spare hardware? Zeos runs in a virtual machine. Alpha 0.2 is tested under QEMU q35 with OVMF UEFI firmware.
Requires QEMU with OVMF UEFI firmware. The path to OVMF_CODE.fd varies by distro.
System requirements
See the verified computers page for the machines we've actually run Zeos on.
Zeos Alpha 0.2 is experimental software for developers and tinkerers. The architecture is locked and it's under active construction — things break, subsystems are still being hardened, and interfaces will change. Do not use it for anything you care about keeping. This is an invitation to explore an OS being built from scratch, not a promise of stability. Found a bug? Open an issue on GitHub.
