Setting up mSSD caching on Acer M3-581TG

view story

http://superuser.com – Apparently the Acer M3-581TG supports some kind of caching using its 20GB internal SSD. I reformatted the hard drive to get rid of all the crapware it came with, and I can't seem to get this feature working again. I've installed Intel RST, but it doesn't seem to work. I've looked in the BIOS, and there is no option to enable SATA; it is locked to AHCI. How can I restore this feature? (HowTos)
