SAN JOSE -- A group of 29 companies led by Compaq, Intel, Microsoft, Phoenix, and Toshiba here today banded together to publish a new power management specification for notebook PCs, desktops, and servers.
The new Advanced Configuration and Power Interface (ACPI) version 2.0 specification is similar to the previous 1.0 release, a power management protocol that was published in December, 1996. Going beyond the original ACPI 1.0 specification, the new release delivers increased power management to a broad array of computers, including corporate and enterprise servers, desktops, and notebook PCs.
ACPI 2.0 also adds support for 64-bit microprocessors used in current and future server applications. Other enhancements for the server market include support for memory, PCI, and PCI-X devices.
The new specification is tuned for Intel Corp.'s new 64-bit microprocessor, dubbed the Itanium. "The new specification provides support for Intel's forthcoming Itanium processor as well as enhancements for both mobile and desktop PCs," said Pat Gelsinger, vice president and chief technology officer of the company's Intel Architecture Group.
Compaq, Intel, Microsoft, Phoenix, and Toshiba led the ACPI 2.0 specification development work.
Also backing the specification include Acer, Acer Labs, Advanced Micro Devices, American Megatrends, ATI, Bull, Cherry, Fujitsu Siemens Computers, Hewlett-Packard, Insyde, Intelliworxx, Intersil, Novell, Silicon Integrated System, TouchStone, Transmeta, Unisys, USAR, Via, and Winbond.
