Product Description The Parallel ATA IDE 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. The board supports Laser Servo (LS-120) diskette technology through the Parallel ATA IDE interfaces. An LS-120 drive can be configured as a boot device by setting the BIOS Setup program's Boot menu to one of the following: • ARMD-FDD (ATAPI removable media device - floppy disk drive) • ARMD-HDD (ATAPI removable media device - hard disk drive) For information about The location of the Parallel ATA IDE connector Refer to Figure 20, page 64 1.7.3.2 Serial ATA Interfaces The ICH6's Serial ATA controller offers four independent Serial ATA ports with a theoretical maximum transfer rate of 150 MB/s per port. One device can be installed on each port for a maximum of four Serial ATA devices. A point-to-point interface is used for host to device connections, unlike Parallel ATA IDE which supports a master/slave configuration and two devices per channel. For compatibility, the underlying Serial ATA functionality is transparent to the operating system. The Serial ATA controller can operate in both legacy and native modes. In legacy mode, standard IDE I/O and IRQ resources are assigned (IRQ 14 and 15). In Native mode, standard PCI Conventional bus resource steering is used. Native mode is the preferred mode for configurations using the Windows* XP and Windows 2000 operating systems. NOTE Many Serial ATA drives use new low-voltage power connectors and require adaptors or power supplies equipped with low-voltage power connectors. For more information, see: http://www.serialata.org/ For information about The location of the Serial ATA IDE connectors Refer to Figure 20, page 64 1.7.3.3 Serial ATA RAID The optional ICH6-R supports RAID (Redundant Array of Independent Drives) level 0 and RAID level 1 on the Serial ATA ports as follows: • RAID 0 supports data striping. Two physical drives, of identical size, can be teamed together to create one logical drive. As data is written or retrieved from the logical drive, both drives operate in parallel, thus increasing the throughput. • RAID 1 supports data mirroring. Two physical drives, of identical size, maintain duplicate sets of all data on separate disk drives. Level 1 provides the highest data reliability because two complete copies of all information are maintained. 27

Product Description

The Parallel ATA IDE 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.
The board supports Laser Servo (LS-120) diskette technology through the Parallel ATA IDE
interfaces.
An LS-120 drive can be configured as a boot device by setting the BIOS Setup
program’s Boot menu to one of the following:
•
ARMD-FDD (ATAPI removable media device – floppy disk drive)
•
ARMD-HDD (ATAPI removable media device – hard disk drive)

Serial ATA Interfaces
The ICH6’s Serial ATA controller offers four independent Serial ATA ports with a theoretical
maximum transfer rate of 150 MB/s per port. One device can be installed on each port for a
maximum of four Serial ATA devices.
A point-to-point interface is used for host to device
connections, unlike Parallel ATA IDE which supports a master/slave configuration and two devices
per channel.
For compatibility, the underlying Serial ATA functionality is transparent to the operating system.
The Serial ATA controller can operate in both legacy and native modes.
In legacy mode, standard
IDE I/O and IRQ resources are assigned (IRQ 14 and 15).
In Native mode, standard PCI
Conventional bus resource steering is used.
Native mode is the preferred mode for configurations
using the Windows* XP and Windows 2000 operating systems.
NOTE
Many Serial ATA drives use new low-voltage power connectors and require adaptors or power
supplies equipped with low-voltage power connectors.

level 1 on the Serial ATA ports as follows:
•
RAID 0 supports data striping.
Two physical drives, of identical size, can be teamed together
to create one logical drive.

•
RAID 1 supports data mirroring.
Two physical drives, of identical size, maintain duplicate sets
of all data on separate disk drives.
Level 1 provides the highest data reliability because two
complete copies of all information are maintained.
