I recently bought a 3020 from eBay and decided to set it up with an old Pentium 4 Sony Vaio. I ran all the checks but could get it to work, then a mate said don't forget the old BIOS settings. As I like to make videos I've made a video on how I set up the BIOS and got the software running. I wasted days thinking the control board wasn't working.

I hope any newbies like me will find it useful.
