I have an older X58 system with I7-920 processor. I have recently upgraded to a Intel SSD. That is when I realized that I needed to be in AHCI mode. Is it possible to go into BIOS and change to AHCI without loosing everything? I would sure hate to have to reload .
Probably will lose everything as using a different bios mode for accessing data on any drives results in a loss of configuration/meta data. Intel provides a tool to migrate data. Works very well in my opinion.
