I have an old Dell Vostro 210s running Windows 7 32bit on a single WB hard drive config'd as AHCI in the BIOS. Working happily. It's my storage for my growing Adobe Lightroom photo catalog (irrelevant I guess).
To cope with the growing storage needs I've installed two 1TB WB Black drives (jumpered to SATA300) with the previous OS drive connected temporarily where the DVD-R was. Once I've imaged the files and OS to the new RAID1, it will be removed.
I have changed the BIOS setting for the SATA controller from AHCI to RAID, setup the two new 1TB drives in a RAID1 and attempted to boot from the previous OS drive, but it gets to about half way and resets the system and tries to boot again. I can set the BIOS back to AHCI and boot ok, but I figure there now needs to be a RAID driver for the embedded Intel ICH10R controller, but I have no idea how to 'inject' it while booted in AHCI mode, or is it something else?
Any help is appreciated.
