Correct - AHCI turns on all the features like queued commands that make SATA actually any more than PATA with a funny cable. > Also, I've already done a couple OS installs on these drives, so it > would appear changing the setting to AHCI will cause me to reinstall > those OS's. Possibly. Some older OS's (Linux and non Linux) also lack AHCI support entirely.
So for a desktop machine, is AHCI really desired? I won't be doing any hotplugging with the drives, command queing would be more for servers and might provide slight overhead on a desktop machine... But from what I have read in this thread, FC6 will not install on my setup *without* AHCI enabled in the BIOS...why is that?
