UEFI firmware may include legacy BIOS compatibility to maintain compatibility with operating systems and option cards that do not support UEFI native operation. [6] [7] [8] Since 2020, all PCs for Intel platforms no longer support Legacy BIOS. [9] The last version of Microsoft Windows to officially support running on PCs which use legacy BIOS ...
UEFI firmware does not execute the code in the MBR, except when booting in legacy BIOS mode through the Compatibility Support Module (CSM). [1] The UEFI specification requires MBR partition tables to be fully supported. [1] However, some UEFI implementations immediately switch to the BIOS-based CSM booting upon detecting certain types of ...
Real mode causes the processor to mostly act as if it was an original 8086, while virtual 8086 mode allows the creation of a virtual machine to allow the running of programs that require real mode in order to run under a protected mode environment. Protected mode is the non-legacy mode of 32-bit x86 processors and the 80286.
An option ROM for the PC platform (i.e. the IBM PC and derived successor computer systems) is a piece of firmware that resides in ROM on an expansion card (or stored along with the main system BIOS), which gets executed to initialize the device and (optionally) add support for the device to the BIOS.
UEFI machines can have one of the following classes, which were used to help ease the transition to UEFI: [96] Class 0: Legacy BIOS; Class 1: UEFI with a CSM interface and no external UEFI interface. The only UEFI interfaces are internal to the firmware. Class 2: UEFI with CSM and external UEFI interfaces, eg. UEFI Boot.
The BIOS boot partition is a partition on a data storage device that GNU GRUB uses on legacy BIOS-based personal computers in order to boot an operating system, when the actual boot device contains a GUID Partition Table (GPT). Such a layout is sometimes referred to as BIOS/GPT boot.
