I have a new Supermicro server (8027R-TRF+) with a Intel RS2WC080 raid controller (this is a rebranded LSI 9240-8i). In the server are 5 Samsung Pro 256Gb SSD's. These are setup as 2 * Raid1 and a hotspare. I am trying to install Windows 2008 essentials server. But during the setup I install the raid driver it can't find the drives anymore. If I change the bios setting "Launch Storage OpRom Policy" from "Legacy only" to "UEFI only" it finds the drives after loading the driver, but the drives aren't visible in the bios, so can't boot from them. Windows then gives an error before installing.
Does anybody know how I can get these to work?
