Flash Cache Module= Allows the computer to support
ReadyDrive. ReadyDrive is a new feature in Windows Vista
that enables PCs equipped with a hybrid hard disk—a new
kind of hard disk that adds flash memory to a standard
mobile PC hard disk drive.
ATA = is a standard interface for connecting storage devices
such as hard disks, solid state disks and CD-ROM drives
inside personal computers.
SATA = is a computer bus primarily designed for transfer of
data between a computer and mass storage devices such
as hard disk drives and optical drives. basically, the updated
new and improved version.
The main advantages over the older parallel ATA interface
are faster data transfer, ability to remove or add devices
while operating (hot swapping), thinner cables that let air
cooling work more efficiently, and more reliable operation
with tighter data integrity checks.
About resetting the options to their original values after
the install, and some more info on what it all does:
Switch from "AHCI" to "ATA": AHCI is primarily Host
Controller support for SATA drives.
If you don't have a hybrid hard disk, then you don't need to re-
enable Flash Cache Module..
If you don't have a SATA drive, then you don't need to re-
enable AHCI... Or if you do have a SATA drive and you
haven't installed the SATA drivers and you don't need the last
little bit of SATA drive performance you DON'T need to re-
enable AHCI. (Many home users leave it disabled because
the performance boost is neglible for the average websurfer).
On the other hand, if you HAVE installed the SATA drivers
and you do want all the performance possible out of your
SATA drive, then DO re-enable AHCI.
And, yes, I cheated. You need 100% concrete info on
something like this. Hope this is what you were looking
for.
Edit : After the install meaning IF they told you to install
an Os with these instructions:
