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.
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.
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 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 ...
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).

In the meantime, she said, Carpenter and other doctors who help provide abortion pills face serious risk if they travel to states without shield laws. Anti-abortion groups praised the indictment.
BIOS interrupt calls perform hardware control or I/O functions requested by a program, return system information to the program, or do both. A key element of the purpose of BIOS calls is abstraction - the BIOS calls perform generally defined functions, and the specific details of how those functions are executed on the particular hardware of the system are encapsulated in the BIOS and hidden ...
