Asus H87MPro c2flashed with bios mod ( small NVmE )Adapter: ICY BOX 60403works great !! Thx for your work guys
@Ludolf @MeatWar @Fernando @Koekieezz Problem solved. It was a bad PCIe NVME M.2 adapter. Swapped that out and the SSD is recognized in Windows. Able to initialize & format. Next test is to see if I can install Windows on it and boot!
