Don’t be dissuaded if you’ve never used Linux before—our how to build a budget bitcoin mining rig-by-step guide makes it simple! 100 on the operating system is a big plus when you’re trying to maximize profitability.
Linux is perfectly happy running from a USB stick plugged into ancient hardware! If you missed the hardware portion of our guide, make sure to check it out first. If you’re a bit nervous because you’ve a complete Linux newbie, don’t be. Simply follow the step-by-step instructions exactly as they’re written, and you’ll be fine. Step 1: Configure BIOS settings Before we even get to Linux, let’s take a minute to make sure that your mining computer’s BIOS settings are in order. You should end up in the BIOS configuration area. Change power options so that the computer automatically turns itself on whenever power is restored.
The reason for this is two-fold: first, it’ll make sure that your miner automatically starts up after a power outage. Second, it makes powering the computer on much easier if you don’t happen to have a power switch connected to the motherboard. Disable all components that you don’t plan to use. For me, that meant disabling onboard audio, one of the SATA controllers, the USB 3. Firewire port, and the serial port.
Exact tweaks vary by motherboard, but setting the PCIe speed to Gen1 is usually a good place to start. No need to change anything now, but make a mental note that you may need to come back and play around a bit if all of your GPUs don’t show up in the OS later. Step 2: Install Xubuntu Desktop on your miner Xubuntu is a lightweight version of Ubuntu, a popular Linux distribution. 3 is the latest LTS release at the time of this guide, so that is what I recommend you use. SATA controller if you disabled it in step 1! When the installation is complete, you should automatically boot into the Xubuntu desktop. Make sure to remove your installation media.
If you plan to manage your mining rig remotely over the internet, you’ll need to forward port 22 on your router to your miner. Make sure that you use a strong Xubuntu password! Putty session by simply right-clicking anywhere inside the Putty window. I highly recommend that you complete the remainder of the guide in this manner, as it eliminates the risk of typos!
