Hi guys, I purchased a SI-PEX40057 PCI Express SATA card which should support RAID, says so on the box. I'm trying to setup dual boot. The expansion card is there for my DVD drive and x2 HDD that I want to put into RAID 1, so one port is left free. All my motherboard SATA ports are taken for the Windows install. Disk Management in Win 10 can see everything, device manager also sees the PCI Marvell controller card. When I go into BIOS however I see that EZ RAID doesn't detect any free drives, No PCIe SATA controllers/PCIe SSDs are presaent and if I go into all the drives connected to the computer, BIOS doesn't see the two drives attached to the SI-PEX40057. Any ideas on how to set things up? My motherboard is the Gigabyte Z370-HD3. I want the second OS to be Linux.
