A point-to-point interface is used for host to device connections, unlike PATA which supports a master/slave configuration and two devices on each channel. For compatibility, the underlying SATA functionality is transparent to the operating system. The SATA controller supports IDE and AHCI configuration and can operate in both legacy and native modes. In Legacy mode, standard ATA I/O and IRQ resources are assigned (IRQ 14 and 15). In Native mode, standard PCI bus resource steering is used.

The PATA interface also supports ATAPI devices (such as CD-ROM drives) and ATA
devices using the transfer modes.
The BIOS supports Logical Block Addressing (LBA) and Extended Cylinder Head Sector
(ECHS) translation modes.
The drive reports the transfer rate and translation mode to
the BIOS.
SATA Interfaces
The ICH10R SATA controller provides five SATA ports and one eSATA port with a
theoretical maximum transfer rate of 3.0 Gb/s on each port.
One device can be
installed on each port for a maximum of four SATA devices.
A point-to-point interface
is used for host to device connections, unlike PATA which supports a master/slave
configuration and two devices on each channel.
For compatibility, the underlying SATA functionality is transparent to the operating
system.
The SATA controller supports IDE and AHCI configuration and can operate in
both legacy and native modes.
In Legacy mode, standard ATA I/O and IRQ resources
are assigned (IRQ 14 and 15).
In Native mode, standard PCI bus resource steering is
used.
Native mode is the preferred mode for configurations using the Windows* XP
and Windows Vista* operating systems.
NOTE
AHCI is only supported by the Microsoft Windows Vista and Microsoft Windows 7
operating systems.
