4. Serial ATA connectors (7-pin SATA1, SATA1)
These next generation connectors support the thin Serial ATA cables
for Serial ATA hard disks. The current Serial ATA interface allows up to
150 MB/s data transfer rate, faster than the standard parallel ATA with
133 MB/s (Ultra ATA/133).

If you wish to create a RAID set, make sure that you have connected
the SATA cable and installed Serial ATA devices. You cannot enter the
SATARaid™ utility and SATA BIOS setup during POST if there are no
connected Serial ATA devices.
5. Chassis intrusion connector (4-1 pin CHASSIS)
This lead is for a chassis designed with intrusion detection feature.
This requires an external detection mechanism such as a chassis
intrusion sensor or microswitch. When you remove any chassis
component, the sensor triggers and sends a high-level signal to this
lead to record a chassis intrusion event.
By default, the pins labeled "Chassis Signal" and "Ground" are shorted
with a jumper cap. If you wish to use the chassis intrusion detection
feature, remove the jumper cap from the pins.
