[OpenIndiana-discuss] How do I swiych from IDE to AHCI mode for my SATA disks, please vet my procedure!

[Hans J. Albertsson]

Now, if somebody can explain why my old and trusty SunRay2 units 
suddenly display scrolling items much much faster.... Say like from 
impossibly slow with large bytewise block rewrites to almost like 
accelerated local displays.

Just because I set the SATA mode to AHCI w/o Legacy mode...

Maybe it's just that sometimes the Byte Fairy is generous.
