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.
Version 1 of the Desktop Management BIOS (DMIBIOS) specification was produced by Phoenix Technologies in or before 1996. [5] [6] Version 2.0 of the Desktop Management BIOS specification was released on March 6, 1996 by American Megatrends (AMI), Award Software, Dell, Intel, Phoenix Technologies, and SystemSoft Corporation. It introduced 16-bit ...
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).

Typical POST screen (AMI BIOS) Typical UEFI-compliant BIOS POST screen (Phoenix Technologies BIOS) Summary screen after POST and before booting an operating system (AMI BIOS) A power-on self-test ( POST ) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on.
The firmware source code is available on the Dell website, [18] but it is not possible to compile the source into a replacement firmware as Dell does not include a build environment. [19] The DRAC provides remote access to the system console (keyboard and screen) allowing the system BIOS to be accessed over the Internet when the server is rebooted.
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 ...
Dell tried to prolong the lifetime of the Nvidia chips in these models with a BIOS update which causes the fan to run more often and thus reduce the strain from repeated heating/cooling cycles on the graphics chip.
Dell became aware that the problem was limited to NVIDIA chip production, the BIOS was updated to A12 which improves thermal control but does not prevent it from reoccurring. The problem associated with NVIDIA GPUs was the chip material used could not stand high temperatures.
