Google-Search – UEFI – Unified Extensible Firmware Interface
UPDATE – 12:45pm Fri 15 – I need to make a note here, .. (for people like myself) – that might take the wording-below-literally, (RE – “UEFI frees any computer“) – I really dont think this technology can be retro-fitted onto existing -/- older computers, ..
UEFI frees any computer from being based around the blueprint and specifications of the original PCs. For instance, it does not specify that a keyboard will only connect via a specific port.
“All it says is that somewhere in the machine there’s a device that can produce keyboard-type information,”
Alternatives to UEFI, such as Open Firmware and Coreboot, do exist and are typically used on computers that do not run chips based on Intel’s x86 architecture
This technology will replace BIOS (Basic input / output system) –
The BIOS is limited to a 16-bit processor mode and 1 MB of addressable space due to the design being based on the IBM 5150 which used the 16-bit Intel 8088. In comparison the UEFI processor mode can be either 32-bit (x86-32) or 64-bit (x86-64 and Itanium). 64-bit UEFI supports long mode which allows applications in the pre-boot execution environment to have direct access to all of the memory using 64-bit addressing
This computer = Intel® Core™2 Duo Processor T7500 (4M Cache, 2.20 GHz, 800 MHz FSB)
Currently running Window 7 (64-bit) – using BIOS, … (Instruction set – 64-bit) – Can access more than, 4GB(s) of RAM –
other facts – Launch Date (T7500 cpu) Q3’06 – meaning third-quarter 2006
PAE – In computing, Physical Address Extension (PAE) is a feature to allow x86 processors to access a physical address space (including random access memory and memory mapped devices) larger than 4 gigabytes.
