# 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** — application management and configuration tool
- **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**

## 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

```bash
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.
