Can I switch from LEGACY to AHCI or RAID


I have configured my pc builds hard drives from day one to use legacy mode hard drive access instead of AHCI or RAID. I'm just learning about these two latter options and wondering if I can switch to either of them without having to reinstall my OS after so doing? Also several links said Intel recommends that Raid be used over AHCI for various reasons.
Granted, I'm using AMD but haven't found any info from them yet.
I'm just wondering if it's possible [without messing things up] for me to switch from legacy IDE to AHCI or RAID setting in BIOS without having to reinstall Mint17?

Easiest way to find out is to switch the setting and see if it boots, if it doesn't, switch it back. It will boot if the 'ahci' kernel module is built-in or in the initrd.

I would use the RAID setting only if you have RAID.

Thanx metaschima,
seemed to boot easier, smoother, faster, and with less read write sound switching to AHCI.
