In the mid-1990s, a facility for supplying new microcode was initially referred to as the Pentium Pro BIOS Update Feature. [18] [19] It was intended that user-mode applications should make a BIOS interrupt call to supply a new "BIOS Update Data Block", which the BIOS would partially validate and save to nonvolatile BIOS memory; this could be supplied to the installed processors on next boot.
On Windows 10 and Windows 11, the activation process can also generate a "digital entitlement", which allows the operating system's hardware and license status to be saved to the activation servers, so that the operating system's license can automatically be restored after a clean installation without the need to enter a product key.
An example of an Intel Upgrade Card. The Intel Upgrade Service was a relatively short-lived and controversial program of Intel that allowed some low-end processors to have additional features unlocked by paying a fee and obtaining an activation code that was then entered in a software program, which ran on Windows 7.
A second prominent example is the set of microcode patches that Intel offered for some of their processor architectures of up to 10 years in age, in a bid to counter the security vulnerabilities discovered in their designs – Spectre and Meltdown – which went public at the start of 2018.
In computing, Machine Check Architecture (MCA) is an Intel and AMD mechanism in which the CPU reports hardware errors to the operating system.. Intel's P6 and Pentium 4 family processors, AMD's K7 and K8 family processors, as well as the Itanium architecture implement a machine check architecture that provides a mechanism for detecting and reporting hardware (machine) errors, such as: system ...
Ivy Bridge is the codename for Intel's 22 nm microarchitecture used in the third generation of the Intel Core processors (Core i7, i5, i3). Ivy Bridge is a die shrink to 22 nm process based on FinFET ("3D") Tri-Gate transistors , from the former generation's 32 nm Sandy Bridge microarchitecture—also known as tick–tock model .
Intel responded by saying, "Intel does not put backdoors in its products, nor do our products give Intel control or access to computing systems without the explicit permission of the end user." [5] and "Intel does not and will not design backdoors for access into its products. Recent reports claiming otherwise are misinformed and blatantly false.
A part of the Intel AMT web management interface, accessible even when the computer is sleeping. Intel Active Management Technology (AMT) is hardware and firmware for remote out-of-band management of select business computers, [1] [2] running on the Intel Management Engine, a microprocessor subsystem not exposed to the user, intended for monitoring, maintenance, updating, and repairing systems ...
