Did you first configure and build the RAID drives in their BIOS utility? You should be showing a RAID set as you boot. As well, some RAID capable MBs will allow those ports to be used as standard drive ports so you need to make sure they're selected to be used as RAID. I've had to go so far as to install XP on a single drive, load the RAID drivers afterwards, detect the RAID array, and then clone the installation onto that array. It's a pain but can be done.
I have been trying to install a RAID setup and I can't get past the windows installation. I have set up the BIOS correctly and I've tried using 2 different RAID floppys and still won't setup.
I start the windows installation and at the F6 prompt I press the F6, when it asks for the drivers I press S and first load the Nvidia RAID driver and then again I load the Nvidia storage driver as per instructions and the installation goes until it starts the windows set up and stops right there. If I only load the Nvidia Raid driver then the set will start. The second floppy I tried using was for SATARAID floppy. Same result If I load the Nvidia SATA storage driver then It stops at Windows installation setup. I have tried installing a bootable setup and a nonbootable with no luck.
