Installing BraiinsOS+ on an Antminer S9

The original software installed on Antminer's mining machines is limited in functionality. That's why in this guide, we will install another software called BraiinsOS+. It is a third-party software developed by the first Bitcoin mining pool, offering more features and allowing, for example, the modification of the machine's power.
There are several methods for installing Braiins OS+ on an ASIC. You can refer to this guide as well as the official Braiins documentation.
Here, we will guide you through the process of easily installing Braiins OS+ directly on the memory of your Antminer using the BOS toolbox software, replacing the original operating system, with detailed steps outlined below.
  1. Power on your Antminer and connect it to your internet box.
  2. Download the BOS toolbox for Windows / Linux.
  3. Unzip the downloaded file and open the bos-toolbox.bat file. Choose the language, and after a few moments, you will see this window:
  1. The Bos toolbox will allow you to easily find the IP address of your Antminer and install BraiinsOS+. If you already know the IP address of your machine, you can skip to step 8. Otherwise, go to the scan tab.
  1. Usually, on home networks, the IP address range is between 192.168.1.1 and 192.168.1.255, so enter "192.168.1.0/24" in the IP range field. If your network is different, please change these addresses accordingly. Then click on "Start".
  2. Attention: if the Antminer has a password, the detection will not work. If that's the case, the simplest solution is to perform a reset.
  3. You should see all the Antminers on your network appear here, and the IP address is 192.168.1.37.
  1. Click on "Back" and then the "Install" tab, enter the previously found IP address, and click on "Start".
If the installation does not work, it may be necessary to perform a reset and try again (see the previous section).
  1. After a few moments, your Antminer will restart, and you will be able to access the Braiins OS+ interface at the specified IP address, here 192.168.1.37, directly in the address bar of your browser. The default username is "root" and there is no default password.
