The raid 1 was setup in the bios, and the drives are connected to the sata 1 and 2 ports on the mother board. If I change Advancd-Advance chipset control-sata controller mode to compatible either drive will boot and Raid is not available, when I change sata controller mode to enhanced, I have 2 options, Sata Raid= enable/disable and Sata ahci= enable/disable. When I enable Sata raid, sata Ahci goes away.
Second , booth drives are identical with the same data and both will boot. I also do have a 3rd drive that was cloned from one of the drives, so I have 3 drives with all the same data that will boot in non-Raid mode.
I need to know how to get the 2 raid drives to boot, as when I set Sata Raid to enable, I get a bosd error as soon as the windows 2003 logo comes up, and goes to reboot.
