Power Management Operation; Power State Mappings; Rapid Storage Manager Raid Option Rom - Intel 6 SERIES CHIPSET - DATASHEET 01-2011 Datasheet

Functional Description
By using the PCH's built-in Intel Rapid Storage Technology, there is no loss of PCI
resources (request/grant pair) or add-in card slot.
®
Intel Rapid Storage Technology functionality requires the following items:
1. The PCH SKU enabled for Intel
2. Intel Rapid Storage Manager RAID Option ROM must be on the platform
3. Intel Rapid Storage Manager drivers, most recent revision.
4. At least two SATA hard disk drives (minimum depends on RAID configuration).
Intel Rapid Storage Technology is not available in the following configurations:
1. The SATA controller is in compatible mode.

Rapid Storage Manager RAID Option ROM

The Intel Rapid Storage Manager RAID Option ROM is a standard PnP Option ROM that
is easily integrated into any System BIOS. When in place, it provides the following
three primary functions:
• Provides a text mode user interface that allows the user to manage the RAID
configuration on the system in a pre-operating system environment. Its feature set
is kept simple to keep size to a minimum, but allows the user to create & delete
RAID volumes and select recovery options when problems occur.
• Provides boot support when using a RAID volume as a boot disk. It does this by
providing Int13 services when a RAID volume needs to be accessed by MS-DOS
applications (such as NTLDR) and by exporting the RAID volumes to the System
BIOS for selection in the boot order.
• At each boot up, provides the user with a status of the RAID volumes and the
option to enter the user interface by pressing CTRL-I.

Power Management Operation

Power management of the PCH SATA controller and ports will cover operations of the
host controller and the SATA wire.

Power State Mappings

The D0 PCI power management state for device is supported by the PCH SATA
controller.
SATA devices may also have multiple power states. From parallel ATA, three device
states are supported through ACPI. They are:
• D0 – Device is working and instantly available.
• D1 – Device enters when it receives a STANDBY IMMEDIATE command. Exit latency
from this state is in seconds
• D3 – From the SATA device's perspective, no different than a D1 state, in that it is
entered using the STANDBY IMMEDIATE command. However, an ACPI method is
also called which will reset the device and then cut its power.
Each of these device states are subsets of the host controller's D0 state.
