Step 1: Downloading the ISO

First, slither over to the official openmamba download page:
https://www.openmamba.org.
Pick the latest stable ISO for x86_64. You’ll see options like
openmamba-Gnome-live-YYYYMMDD.iso or openmamba-KDE-live-YYYYMMDD.iso.

• Click the desired ISO link.
• Save it to a known folder on your current OS.
• Check the file size checks out (usually ~2 GB).

Step 2: Verifying the ISO

Verification is like checking a snake’s fangs—don’t skip it. Download the
corresponding .sha256 checksum file or find the hash on the site.

On Linux or macOS, open a terminal and run:

sha256sum openmamba-.iso
  

Compare the output to the value from the website. If they match, you’re venom-ready. If not, re-download.

Step 3: Creating a Bootable USB Drive

Time to gift your USB stick some mamba power. You can use
Rufus on Windows, Etcher on all platforms, or dd on Linux.

Using dd on Linux

• Insert your USB drive and identify it:

  lsblk

• Unmount any auto-mounted partitions:

  umount /dev/sdX  # replace X with your drive letter

• Write the ISO:

  sudo dd if=openmamba-YYYYMMDD.iso of=/dev/sdX bs=4M status=progress  sync

Warning: Using the wrong device path can erase your entire hard drive. Always double-check!

Step 4: BIOS/UEFI Configuration

Restart your machine. Enter BIOS/UEFI by pressing F2, Del, or the key your system demands.
Locate Boot Order or UEFI Boot Priority and place your USB drive at the top.

If your motherboard likes Secure Boot, you might need to disable it. But fear not: openmamba supports
Secure Boot in newer versions. Check the docs at
https://wiki.openmamba.org.

Step 5: Booting the Installer

Save and exit BIOS. Your system should boot into a colorful openmamba live session. If you see a snake
logo dancing, congratulations—you’ve entered the jungle.

Select Start openmamba Live and let the OS roar to life. Performance may be slightly slower
off USB, but we only need this environment for installation.

Step 6: Graphical Installer Walkthrough

The openmamba installer—codename Thanatos—is intuitive. Follow along:

1. Language and Keyboard

• Choose your preferred language.
• Select your keyboard layout (e.g., US English).

2. License Agreement

Review the GPL and related licenses. You can safely scroll to the end and click I Agree.
Freedom tastes better when you actually read the license, but we won’t judge if you skim.

3. Disk Partitioning

Decide between:

• Automatic Partitioning (recommended for newbs)
• Manual Partitioning (for seasoned pros)

For manual mode, create at least:

• / (root): 15–20 GB, ext4 or btrfs
• swap: equal to your RAM size (or omit if you have plenty of RAM)
• /home: rest of the disk, ext4 or btrfs

4. User Setup

• Enter your full name, username, and a strong password (no password123!).
• Decide if you want automatic login (not recommended for security-conscious serpents).

5. Software Selection

Pick your desktop environment: KDE Plasma, GNOME, Xfce, LXQt, or MATE. Think of it as choosing your snake charm:
sleek, powerful, or lightweight.

6. Installing

Click Install and watch the progress bar slither forward. Grab a coffee, do a little dance, or
cuddle your favorite plush boa while you wait—this takes 5–15 minutes.

Step 7: First Boot and Post-Install Setup

Installation finished? Reboot and remove the USB stick when prompted. You’ll be greeted by your new openmamba login screen.

Updating the System

Open a terminal (Konsole, GNOME Terminal, etc.) and run:

sudo mamba refresh
sudo mamba update
  

Note: openmamba uses mamba (not to be confused with the Python installer of the same name).
It’s lightning-fast.

Installing Additional Drivers

• For NVIDIA cards:

  sudo mamba install nvidia-driver

• For Wi-Fi chipsets:

  sudo mamba install broadcom-wl

Setting Up Software Repositories

You might add community or testing repos. Edit
/etc/zypp/repos.d/ files or use the Software Sources GUI.
