Drop the BIOS completely in favor of UEFI by 2020. This is one of Intel 's plans for the next few years and it is not surprising to those in the know, the question of an imminent disappearance. BIOS already being a hot topic for a few years now in the small world of computing.
This Intel project, however, we learn about it through a document that UEFI.org published recently. It is more precisely a slide show hinting at Intel's plan of action to permanently scrap the BIOS – which is indeed starting to age its arteries. It remains to be seen whether this Intel roadmap will succeed in executing as planned over the next three years that the firm agrees on the matter.
Anyway, it may be necessary to take stock of what BIOS (Basic Input Output System) and UEFI (Unified Extensible Firmware Interface) are… Behind these barbaric acronyms hides simple directly integrated systems to the motherboards of any computer, making it possible in particular to relay between the components and the operating system during startup.
BIOS and UEFI: a coexistence that is no longer intended to last …
If initially the BIOS went it alone, the latter has for several years been supported in its task by UEFI, which does roughly the same job, but with a more attractive interface for the user and more complete functionalities (in particular on the side of certain functions linked to the network). One could then wonder why UEFI has not – already – gained the upper hand over its little comrade, but it would be without counting on certain compatibility problems.
The first versions of UEFI indeed make it possible to go through the BIOS to allow the backward compatibility of certain software or hardware elements that could not function otherwise. It is therefore a question of gradually switching to the class 3 version of UEFI to do without this backward compatibility.
The main advantage of this migration to the new version of the system (beyond the fact of simplifying things) concerns the issue of security. Intel recalls for example that – unlike UEFI – the BIOS does not benefit from secure boot.
