Thanks in advance
Start with BIOS settings on motherboard. You usually have three options after a power loss event: Shut Off, Turn On, Return to Previous State
Next would depend on your operating system. For Windows, add program to startup folder. For Linux, add program to Startup Applications.
Follow the directions provided on the pool website. If you are just starting, I would get some equipment (maybe just one video card) and get that up and running.
