CM1-86DX2
3.6 IDE / SD / SATA Controller
The integrated Serial ATA controller processes host commands and transfers data between the
host and Serial ATA devices. With respect to the transfer rate, the integrated SATA controller
supports first generation SATA (1.5 Gbit/s). The CM1-86DX2 provides one SATA connector
(X11) for connecting a SATA disk drive or an optical SATA drive.
The MicroSD-Card is driven as an IDE drive and has no hot-plug capability.
An mSATA device can be connected at the MiniPCIe socket (X10) but the mSATA device will
use the SATA controller exclusively, and no external SATA device will function.
The SATA controller can operate in two modes:
 SATA in legacy mode
 SATA in native mode (default setting)
IDE-Controller Features
 Compatible with the ATA/ATAPI-6 specification and supports two IDE channels with up to
four drives
