American Megatrends Inc. (AMI), a global leader in BIOS and UEFI firmware, server and remote management tools, data storage products and unique solutions based on the Linux® and Android™ operating systems, is pleased to announce support for the AHCI firmware update, outlined in the ATA specification, in AMI's flagship Aptio® V UEFI firmware.

The Advanced Host Controller Interface (AHCI) is a specification by Intel® that outlines the software communication interface between AHCI and Serial ATA (SATA) devices. To allow customers to apply firmware updates to SATA storage devices running Aptio® V UEFI firmware, AMI has added support for the latest AHCI firmware update, specifically the AHCICapsuleUpdate module.

The AHCI firmware update for SATA devices is supported through the Windows® Capsule Interface and AMI has developed a standard method for publishing an EFI System Resource Table (ESRT) entry for SATA device(s) identified on the system. When a new firmware update package is identified for the SATA drive(s), the device driver will distribute the firmware update capsule package and the AHCICapsuleUpdate module will receive the updates from the package using capsule update mechanism. Once the module has these updates, it will then instruct the SATA device(s) to install and apply the new firmware updates.

By providing support for the AHCI firmware update, AMI enables customers to easily apply generic updates to multiple identical drives at the same time, saving time and effort.
