S-ATA Connectors: CN21, CN22
The S-ATA header is used to connect the S-ATA device to the motherboard.
These connectors support the thin Serial ATA cables for primary internal storage devices.
The current Serial ATA interface allows up to 150MB/s data transfer rate, faster than
the standard parallel ATA with 133MB/s (Ultra ATA/133).
Serial ATA solution:
1. In legacy operating system (Win98, WinME, WinNT, DOS) enviromemt,
using Serial ATA will disable one of the IDE channels from ICH5R south
bridge chipset. See the BIOS section for correct settings.
2. The Serial ATA cable is smaller and more flexible allowing easier routing
inside the chassis. The lower pin count of the Serial ATA cable eliminates
the problem caused by the wide, flat ribbon cables of the Parallel ATA
interface.
