In this second installment of our DIY Ethereum mining guide, we’ll look at how to install and configure Linux to setup your rig as an automated, remotely-manageable appliance. Don’t be dissuaded if you’ve never used Linux before—our step-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 xubuntu litecoin mining 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.
