Классический BIOS
UEFI
История
• Изначально EFI создавалась для первых систем Intel-HP Itanium в середине 1990-
х годов. Спецификация EFI 1.10 была выпущена 1 декабря 2002. Она включала
модель драйвера EFI, а также несколько незначительных улучшений по сравнению с
версией 1.02.
• В 2005 году Intel внесла эту спецификацию в UEFI Forum, который теперь
ответственен за развитие и продвижение EFI. EFI был переименован в Unified EFI
(UEFI), чтобы отразить это изменение, при этом большая часть документации
использует оба термина.
• UEFI Forum выпустил спецификацию 2.1 UEFI 7 января 2007. Она добавила и
улучшила криптографию, установление подлинности сети и
архитектуру пользовательского интерфейса.
• Версия 2.3.1 была принята в апреле 2011.
• Версия 2.4 была принята в июле 2013.
• Версия 2.5 была принята в апреле 2015.
