The Intel RAID ROM is the firmware in the motherboard BIOS that is used to create the RAID array. Note: The RST drivers can be used for RAID and also on a single drive as it contains an AHCI driver. There is a bug in the version 12.5.0.1066 RST driver, which cause TRIM commands not to pass through the RAID driver to the drives.
As an interim resolution, Intel recommends changing the drive controller to AHCI or RAID before installing an operating system. [3] (It may also be necessary to load chipset-specific AHCI or RAID drivers at installation time, for example from a USB flash drive).
An option ROM for the PC platform (i.e. the IBM PC and derived successor computer systems) is a piece of firmware that resides in ROM on an expansion card (or stored along with the main system BIOS), which gets executed to initialize the device and (optionally) add support for the device to the BIOS.
RAID controller Intel RS2WG160 RAID controller. SAS/SATA, 6 Gbit/s, 16 ports, PCIe 2.0. Reference unknown. 2010 Warm River Motherboard Intel DG41WV desktop motherboard. Micro-ATX form factor, LGA 775, G41 chipset . Warm River, Idaho, USA. 2010 Warm Springs Motherboard Intel WS440BX motherboard. Based on the 440BX chipset.
The appropriate driver must be loaded into the operating system to enable NCQ on the host bus adapter. [3] Many newer chipsets support the Advanced Host Controller Interface (AHCI), which allows operating systems to universally control them and enable NCQ. DragonFly BSD has supported AHCI with NCQ since 2.3 in 2009.
SRT is managed by Intel Rapid Storage Technology software version 10.5 or later, [2] and implemented both in its device driver and in the Z68 motherboard's firmware . It is available only when the (integrated) disk controller is configured in RAID mode (but not AHCI or IDE modes) by implementing a style of RAID 0 striping.
For a short time in March 2010, users were led to believe that the Intel Rapid Storage Technology (RST) 9.6 (and later) drivers in Windows 7 supported TRIM on RAID volumes, but Intel later clarified that TRIM was supported for the BIOS settings of AHCI mode and RAID mode, but not if the drive was part of a RAID volume. [56] As of August 2012 ...
As of February 2007 Intel started integrating their own Matrix RAID controller in their more upmarket motherboards, giving control over 4 devices and an additional 2 SATA connectors, and totalling 6 SATA connections (3 Gbit/s each). For backward compatibility one IDE connector able to connect 2 ATA devices (100 Mbit/s) is also present.
