Setting non-AHCI mode (i.e. IDE or Combined mode) in the BIOS will allow the user to boot into Windows, and thereby the required registry change can be performed. Consequently, the user then has the option of continuing to use the system in Combined mode or switching to AHCI mode. [8]
It is confirmed that with native Microsoft drivers the TRIM command works on Windows 7 in AHCI and legacy IDE / ATA Mode. [44] Windows 8 and later Windows operating systems support the unmap command for devices that use the SCSI driver stack, including USB Attached SCSI Protocol (UASP).
[4] [5] Linux kernels support AHCI natively since version 2.6.19, and FreeBSD fully supports AHCI since version 8.0. Windows Vista and Windows 7 also natively support AHCI, but their AHCI support (via the msahci service) must be manually enabled via registry editing if controller support was not present during their initial install.
In BIOS mode the legacy/BIOS booting is under CSMCORE. In true UEFI mode the RST is controlled under SataDriver / RstVmdDriver in BIOS. 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.
Six SATA 3 Gbit/s ports in either legacy IDE or AHCI mode. Can support external eSATA; Intel High Definition Audio; Integrated gigabit LAN; AHCI support; Two EHCI host controllers (which support up to twelve USB 2.0 connections) with companion UHCI controllers to handle low-speed and full-speed USB devices; This part has the following variants:
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. The user can select write-back (so-called maximized mode) or write-through (so-called enhanced mode) caching strategy. The maximum utilizable cache size on the SSD is 64 GB.
Intel Cannon Lake Platform Controller Hub die. The PCH architecture supersedes Intel's previous Hub Architecture, with its design addressing the eventual problematic performance bottleneck between the processor and the motherboard.
A 3.5-inch Serial ATA hard disk drive A 2.5-inch Serial ATA solid-state drive. SATA was announced in 2000 [4] [5] in order to provide several advantages over the earlier PATA interface such as reduced cable size and cost (seven conductors instead of 40 or 80), native hot swapping, faster data transfer through higher signaling rates, and more efficient transfer through an (optional) I/O queuing ...
