The Intel Matrix 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:
Power Management Operation
Power management of the ICH8 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 ICH8 SATA
controller.
SATA devices may also have multiple power states. From parallel ATA, three device
states are supported through ACPI. They are:
Each of these device states are subsets of the host controller’s D0 state.
Finally, SATA defines three PHY layer power states, which have no equivalent mappings
to parallel ATA. They are:
Since these states have much lower exit latency than the ACPI D1 and D3 states, the
SATA controller defines these states as sub-states of the device D0 state.
• Provides a text mode user interface that allows the user to manage the RAID
• Provides boot support when using a RAID volume as a boot disk. It does this by
• At each boot up, provides the user with a status of the RAID volumes and the

• D1 – device enters when it receives a STANDBY IMMEDIATE command. Exit latency
• D3 – from the SATA device’s perspective, no different than a D1 state, in that it is
• PHY READY – PHY logic and PLL are both on and active
• Partial – PHY logic is powered, but in a reduced state. Exit latency is no longer than
• Slumber – PHY logic is powered, but in a reduced state. Exit latency can be up to
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.

applications (such as NTLDR) and by exporting the RAID volumes to the System
BIOS for selection in the boot order.
