P20378 S-ATA Controller
Possible values of an option:
[S-ATA], [RAID], [Disabled]
The option description:
The given option allows to configure additional SATA the RAID-controler integrated on the motherboard. It does not affect the standard IDE/SATA-controler of a chipset. The choice [S-ATA] translates the additional controler in a mode of the normal SATA-controler, setting [RAID] allows to unite the disks connected to this controler in a RAID, [Disabled] traditionally disconnects the additional controler.
To connect hard disks and other devices to the additional controler it is necessary in the event that the standard controler of a chipset does not support the demanded interface (we tell, it is necessary to connect an IDE-drive of optical disks, and the chipset controler allows to use only SATA-devices), or does not provide necessary functions (for example, you want to unite hard disks in a RAID, but this functional misses in chipset the controler). In remaining cases all available drives are better for connecting to the standard IDE/SATA-controler of a chipset, and additional — to disconnect. It simplifies operating system setting, plus, releases resources occupied with the controler, making their accessible to other devices.
