Digital transformation: Making it work in the real world

It takes more than shiny new technologies to remake business processes. Here are a few ideas on how to make digital transformation projects work in your organisation.

The UEFI Forum has announced availability of the Advanced Configuration and Power Interface (ACPI) Specification v6.1 and the Unified Extensible Firmware Interface (UEFI) Specification v2.6.

These updates allow PCs to offer enhanced mobility and manageability for customer and enterprise levels.

New to the ACPI Specification v6.1 we have:

  • Interrupt-signaled events for expanded hardware-reduced platform support and improved system-on-chip designs.
  • Standardized ARMv8-A processor support for "firmware-first" hardware error handling and reporting, including SEA and SEI notification types in the Hardware Error Source Table (HEST).

The last ACPI revision was published in April 2015.

Added to UEFI Specification v2.6 are the following:

  • Enriched ability for agents in the system to provide better user interface support prior to launching of the OS through additional Image and Font information.
  • Formal API definition for RAM Disk Protocol.
  • New Wireless MAC Connection Protocol interface simplifies wireless network support and future radio technology versions.
  • ARM error reporting extensions for the Common Platform Error Record (CPER), allowing ARMv8-A systems to implement "firmware-first" hardware error handling and reporting.

UEFI supports Itanium, x86, x86-64, ARM and ARM64 processors.
