2. Configure the Rename-command configuration item "
Ethos is a system of mining depth customization based on Linux.Because the system relative to Windows, the volume is very small, so you can burn directly in the U disk, save a hard drive money. And the system takes up less resources and is more stable for the same configuration than the Windows system.Ethos system, is made by a foreign team. and the U disk price needs 39 dollars.
