I am trying to implement sata raid 0 with a PCI card built on the silicon image 3112 chip (Koutech PSA150). I can create the array in the card bios utility, start windows install process and load the drivers, and even format the logical volume and write the system files. When it comes time to reboot, my board doesn't detect the drives on the PCI card. The drives work fine if connected to the onboard sata controller, but this cheap board has the ICH6, not the ICH6R, so I need to use the expansion card for raid capability It's a ECS 915p-a rev 1.2 board using an ami bios. I have flashed up to the latest bios available from ECS. I have enabled the 'boot from other device' option, but it doesn't detect the drives. I read that disabling the auto detect on the board's sata ports might help, but I haven't found a way to do that in the AMI bios. hopefully, someone here smarter than me might have a suggestion.
