LogoFAIL is a security vulnerability and exploit thereof that affects computer motherboard firmware with TianoCore EDK II, including Insyde Software's InsydeH2O modules and similar code in AMI and Phoenix firmware, which are commonly found on both Intel and AMD motherboards, and which enable loading of custom boot logos.
An InsydeH20 screen. The company's product portfolio includes InsydeH2O BIOS (Insyde Software's implementation of the Intel Platform Innovation Framework for UEFI/EFI [1]), BlinkBoot, a UEFI-based boot loader for enabling Internet of Things devices, [2] and Supervyse, which is a full-featured systems management/BMC firmware for providing out-of-band remote management for server computers.
In computing, BIOS (/ ˈ b aɪ ɒ s,-oʊ s /, BY-oss, -ohss; Basic Input/Output System, also known as the System BIOS, ROM BIOS, BIOS ROM or PC BIOS) is a type of firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup). [1]
However, BIOS manufacturers and OEMs have relied on SMM for newer functionality like Advanced Configuration and Power Interface (ACPI). [9] [10] Some uses of the System Management Mode are: Handle system events like memory or chipset errors; Manage system safety functions, such as shutdown on high CPU temperature; System Management BIOS (SMBIOS)
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. [8]
Advanced Configuration and Power Interface (ACPI) is an open standard that operating systems can use to discover and configure computer hardware components, to perform power management (e.g. putting unused hardware components to sleep), auto configuration (e.g. Plug and Play and hot swapping), and status monitoring.
The AMI WinBIOS was a 1994 update to AMIBIOS, with a GUI setup screen that mimicked the appearance of Windows 3.1 and supported mouse navigation, unusual at the time. WinBIOS was viewed favorably by Anand Lal Shimpi at AnandTech , [ 32 ] but described by Thomas Pabst at Tom's Hardware as a "big disappointment", in part because of problems with ...
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.
