  2. UEFI - Wikipedia

    en.wikipedia.org/wiki/UEFI

    The original motivation for EFI came during early development of the first Intel–HP Itanium systems in the mid-1990s. BIOS limitations (such as 16-bit real mode, 1 MB addressable memory space, [7] assembly language programming, and PC AT hardware) had become too restrictive for the larger server platforms Itanium was targeting.

    The third BIOS virus was a technique presented by John Heasman, principal security consultant for UK-based Next-Generation Security Software. In 2006, at the Black Hat Security Conference, he showed how to elevate privileges and read physical memory, using malicious procedures that replaced normal ACPI functions stored in flash memory.

  4. System Management BIOS - Wikipedia

    en.wikipedia.org/wiki/System_Management_BIOS

    In computing, the System Management BIOS (SMBIOS) specification defines data structures (and access methods) that can be used to read management information produced by the BIOS of a computer. [1] This eliminates the need for the operating system to probe hardware directly to discover what devices are present in the computer.

  5. coreboot - Wikipedia

    en.wikipedia.org/wiki/Coreboot

    coreboot, formerly known as LinuxBIOS, [5] is a software project aimed at replacing proprietary firmware (BIOS or UEFI) found in most computers with a lightweight firmware designed to perform only the minimum number of tasks necessary to load and run a modern 32-bit or 64-bit operating system.

  6. Nonvolatile BIOS memory - Wikipedia

    en.wikipedia.org/wiki/Nonvolatile_BIOS_memory

    It is referred to as non-volatile memory or NVRAM because, after the system loses power, it does retain state by virtue of the CMOS battery. When the battery fails, BIOS settings are reset to their defaults. The battery can also be used to power a real time clock (RTC) and the RTC, NVRAM and battery may be integrated into a single component.

  8. Pre-boot authentication - Wikipedia

    en.wikipedia.org/wiki/Pre-boot_authentication

    Without cryptographic protection of a hardware (TPM) supported secure boot environment, PBA is easily defeated with Evil Maid style of attacks. However, with modern hardware (including TPM or cryptographic multi-factor authentication) most FDE solutions are able to ensure that removal of hardware for brute-force attacks is no longer possible.
