I own a Latitude E6400 with one internal ssd and one ssd in the modular bay. I managed to update my bios with the option rom of the M6500, which allows raid0 and raid 1. The only obstacle i need to tacle in order to create a raid0 configuration between the 2 disks is that the disk in the modular bay is marked as external. Has anyone already managed to reverse the option rom to allow a raid0 configuration to span over internal and "external" disks ? I attached the option rom i use. Thanks in advance.
