DGX OS and System Software

The Dell Pro Max GB10 ships with NVIDIA DGX OS 7, a purpose-built Linux distribution for AI development.

1. DGX OS 7 Overview

Base: Ubuntu 24.04 LTS (Noble Numbat)
Kernel: Linux 6.8
Architecture: ARM64 (aarch64)
NVIDIA branding: Also called "DGX OS for DGX Spark"

DGX OS is not a separate distribution — it is Ubuntu 24.04 with NVIDIA's customizations layered on top:

Pre-configured NVIDIA GPU drivers
CUDA toolkit and libraries
Platform-specific optimizations and configurations
Diagnostic and monitoring tools
System-specific firmware management

2. Pre-installed Software Stack

The system ships ready to run AI workloads with:

CUDA toolkit + cuDNN — GPU compute API, compiler, and deep learning primitives
NVIDIA drivers — optimized for GB10 Blackwell GPU
Docker + NVIDIA Container Runtime — container support out of the box (T0 Spec)
NVIDIA Sync — cross-platform desktop app for remote device management (see §8)
DGX Dashboard — system monitoring with integrated JupyterLab
NGC — access to NVIDIA GPU Cloud containerized applications and models
AI Enterprise — enterprise-grade AI software assets and services
Python — system Python plus development environments
GCC — ARM-native compiler toolchain
OpenJDK — Java runtime

For AI frameworks, see ai-frameworks.

3. First Boot and Setup

DGX OS uses a setup wizard on first boot that handles:

User account creation
Network configuration
System preferences
Software configuration

The process is designed for fast onboarding. See setup-and-config for detailed walkthrough.

4. OS Reinstallation

Dell provides a documented process for reinstalling DGX OS:

Boot to GRUB menu
Select "Install DGX OS 7.2.1 for DGX Spark" from DGX Spark Installation Options
Installation takes approximately 25-30 minutes

Source: Dell Support KB Article

5. Firmware Updates

Dell and NVIDIA use different firmware signing keys. Dell units require Dell-signed firmware payloads, not generic DGX Spark firmware. (T1 Documented, ServeTheHome)

Update Procedure

sudo apt update
sudo apt upgrade
sudo fwupdmgr refresh
sudo fwupdmgr upgrade

The GUI alternative: DGX Dashboard → Settings → Update (triggers reboot for BIOS/firmware changes).

Firmware updates take approximately 1-2 minutes plus a reboot.

6. Support Lifecycle

Guaranteed updates: 2 years from purchase (T2, Jeff Geerling)
Support channel: Dell provides support for Dell Pro Max units (not NVIDIA directly)
Implication: Dell partners provide ongoing firmware and support, distinct from NVIDIA's DGX Spark support

7. Important Notes

ARM-only: All software must be ARM64/aarch64 compatible. x86 binaries will not run natively.
No Windows: This system does not support Windows installation.
Package management: Standard Ubuntu apt package manager, plus NVIDIA's own repositories.
NVIDIA kernel: The system requires NVIDIA's specific kernel for full hardware compatibility.

8. NVIDIA Sync (Remote Management App)

NVIDIA Sync is a cross-platform desktop application (macOS, Windows, Linux) that connects a laptop/workstation to the DGX Spark / Dell Pro Max GB10 over the local network. (T1 Documented, build.nvidia.com/spark)

Installation

Platform	Method
macOS	Download DMG, drag to Applications
Windows	Run installer executable (auto-launches)
Linux (Debian/Ubuntu)	Add NVIDIA repository, `apt install`

Connection Setup

Device and laptop must be on the same LAN
Provide device hostname (mDNS format: spark-abcd.local) or IP address
Enter username and password
Sync generates an SSH keypair, installs the public key on the device, then discards the stored password
Creates an SSH alias for future connections (password-free after setup)

Features

SSH connection control — toggle device connectivity on/off
Working directory configuration — set default launch location
Application launchers — one-click launch for:
- Terminal (SSH session)
- DGX Dashboard (web UI)
- VS Code (remote SSH)
- Cursor (remote SSH)
- NVIDIA AI Workbench
Custom port forwarding — map localhost ports to remote services (e.g., JupyterLab on port 8888, API servers, etc.)

Network Discovery

Uses mDNS (.local suffix) for automatic hostname resolution on the LAN
Falls back to direct IP address if mDNS fails
Requires same network — no WAN/internet remote access built in

Troubleshooting

mDNS resolution failure: Use IP address instead of hostname
Connection timeout during boot: Wait for device to fully boot
Authentication failure: Reconfigure connection in Sync app

Key Relationships

Runs on: gb10-superchip
Provides platform for: ai-frameworks
Setup process: setup-and-config
