I have searched several times for a feature that's listed on the feature list for this motherboard, the SATA HOTPLUG feature. Usually you have to manually turn this on. I can't seem to find it in the BIOS, no matter where I look. I have a fairly recent BIOS on this, too. Whatever was current in June/July 2020 is what I used on here when I upgraded to a 3950x processor. Does anyone else have this board and know where the hotplug feature is, so I can find it and enable it (it's not enabled, I tried hooking things up, to no avail). This would be super-useful as I tend to use my 500gb SSD's to transfer large amounts of project data between computers, and my old Asus Max Hero VII on the intel system always had a toggle per-port for it. There is also a slightly more recent & cost-reduced Phantom Gaming 4S, this is not the S model, it's the original one. I looked up in the PDF manual for the board on Asrock's website, no luck. Totally stumped - on the dumbest of all things here. The board / PC is great but I just am dumbfounded that it's not here to toggle. When writing out a response, my tech level can be assumed to be fairly good... been doing PC hardware since when the 486 was common in the mid 90's. No-where near perfect or a know-it-all though, sadly. Thanks for any help you can provide.
