5. Silicon Image ® Sil5723 Serial ATA connectors
(7-pin SATA_E1 [orange, port 0], SATA_E2 [white, port 1])
These connectors are for the Serial ATA signal cables for Serial ATA hard
disk drives. If you installed Serial ATA hard disk drives, you can create a EZ
Backup or a Super Speed configuration with the Drive Xpert Technology
through the onboard Silicon Image ® Sil5723 controller.
Before using the Drive Xpert technology, make sure that you have connected
the SATA signal cables and installed SATA hard disk drives.
Refer to 4.3.11 ASUS Drive Xpert for detailed application instructions.
• The SATA_E1 (orange, port 0) and SATA_E2 (white, port 1) ports are for
SATA hard drives only. ATAPI device is not supported.
• Before using the Drive Xpert function, ensure that you have back up all
your data in your hard disks.
EZ Backup erases all original data in the hard disk connected to the
SATA_E2 (white, port 1) connector on the motherboard.
Super Speed erases all original data in both hard disks.
