Microsoft has pushed back its plans to support a new type of PC firmware, called UEFI, or United Extensible Firmware Interface, which has begun working its way into the PC market.
Microsoft said in a presentation during last week’s Intel Developer Forum in San Francisco that the software giant would not roll out UEFI support—adopting the new firmware, which was created for Itanium servers but then repositioned to take over for PC BIOS or basic input output system software—in its Longhorn server, due in 2007.
However, the company will not offer support for UEFI in the first version of Windows Vista, its new PC OS slated for launch in November, as it had planned originally.
UEFI support will be added to “subsequent 64-bit client releases,” instead, according to an IDF presentation by Andrew Ritz, development manager at the company, in Redmond, Wash.
The new stance reverses a potion that both Vista and Longhorn Server would support both EFI and BIOS.
