Ya think? Lol.
I also wrote to Gigabyte eSupport. They said "Unfortunately this board is quite old and there are no full Windows 10 driver support for this board. If you must use Windows 10, it would be suggested you look into a newer board with Windows 10 driver support. We do not manufacture adapter cards."
I ordered the 4-port PCI card a few days ago and it's scheduled to be here on the 19th. I'll keep the IO Crest 8-port PCIe card too. Hopefully, they'll be no problem with the PCI card and no conflicts with having both installed at the same time. My luck hasn't been too good with this conversion. I lost 3 hard drives, too. I haven't heard back from UPS about the 2 that I put in their drop box. I've been really busy and haven't been able to call them back yet. Tomorrow's out as I'll have another long day but Monday is free so I'll give them a call then. I ordered 2 more from Western Digital because the hard drives that I received from Amazon were so old that when I checked their warranties with Western Digital, they had expired in 2016.
At least I can say that I tried to get what I wanted.
I'll let you know how the PCI card works.
