MultiTaction Base Linux Image

MultiTaction Base Linux Image is a disk image meant for SuperMicro PCs used by MultiTaction. The image can be downloaded below and burned to a USB disk that can be used to boot and flash the hard drive of a PC.

MultiTaction Base Linux Image - Ubuntu 24.04 Noble (UEFI boot)

Engineering preview. These are manual local builds — not CI-produced artefacts. CI auto-publishing will replace them once the build pipeline is green.

  • Full: NVIDIA + Magewell kernel modules are AKV-signed against the MT MOK certificate. Secure Boot may be left on if the MT MOK cert is already enrolled on the target firmware; otherwise enrol via mokutil on first boot or disable Secure Boot.
  • Slim: NVIDIA + Magewell drivers install via DKMS on first boot using an ephemeral per-machine key. Secure Boot must be disabled for these to load.

Full Variant (pre-configured with MT applications and containerized Canvus Server, signed modules):

Slim Variant (base OS only; applications installed at first boot):

How to use this image

The downloaded .img.xz file is a rewriter image: you write it to a USB drive, boot the target PC from that USB, and it flashes the target's internal disk with the MT software stack. It is not a live image — booting from USB will overwrite the PC's primary disk.

1. Prepare a USB drive (≥ 8 GB). All data on the USB will be erased.

2. Write the image to the USB.

On Linux (replace /dev/sdX with your USB device — check with lsblk first; getting this wrong will overwrite the wrong disk):

xz -d -k multitaction-base-image-noble-slim-build40908.img.xz
sudo dd if=multitaction-base-image-noble-slim-build40908.img \
        of=/dev/sdX bs=4M status=progress conv=fsync
sync

On Windows or macOS: use balenaEtcher — it accepts the .img.xz file directly (no manual decompress needed) and refuses to write to non-removable drives.

3. Boot the target PC from the USB. Enter UEFI boot menu (usually F11 / F12 / Del at power-on), select the USB drive. Secure Boot may be left enabled — the image ships with signed shim + GRUB.

4. The installer runs automatically. It wipes the PC's primary internal disk, writes the MT OS image, then reboots. Total time is typically 5-15 minutes depending on disk speed. Remove the USB before reboot or the installer will start again.

5. First boot of the installed system auto-logs in as the multi user and starts MT Launcher. For the Slim variant, first boot also runs an initial APT-based install of MT applications — requires network access. The Full variant is airgap-ready and contains everything baked in.

Which variant to choose

Variant Size (xz) First-boot network needed Use when
Full ~6 GB No Production walls, integrator handover, sites with restricted internet, fastest first boot
Slim ~2 GB Yes (APT) Dev / staging, frequent re-flashing, sites with reliable internet, when you want the latest MT app versions at install time

If unsure: pick Full.
