Thank you. I've updated the BIOS settings segment in the build description.BTW, this is a build description, not a guide. If it was a guide, you would not read about why I build this system and why I chose these components.I didn't use a USB 2 header cable. I use the Real Panel USB 3 (blue) port. Since the header ports are usually in the higher count of USB ports and the El Cappy USB default maximum USB count is 15 ports (USB 3 count as 2 ports), I used the Real Panel USB 3 (blue) port. Worked.
