So, I'm trying to reconfigure this computer's drives as a mirror set instead of a stripe set and its not working. Its a Gigabyte GA-8KNXP motherboard with a SIL 3112A SATA RAID controller. SATA is set to RAID mode in the BIOS and the RAID controller's setup sees both drives and lets me create a mirror set with them. But when I run Windows setup (I have the F6 drivers on a floppy) it sees the RAID members as individual drives but won't let me install Windows on either. WTF?
