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.
Some hardware vendors, notably IBM and Lenovo, use the term microcode interchangeably with firmware. In this context, all code within a device is termed microcode, whether it is microcode or machine code. For instance, updates to a hard disk drive's microcode often encompass updates to both its microcode and firmware. [3]
The BIOS contain patches to the processor microcode that fix errors in the initial processor microcode; microcode is loaded into processor's SRAM so reprogramming is not persistent, thus loading of microcode updates is performed each time the system is powered up.
Intel promised microcode updates to resolve the vulnerability. [1] The microcode patches have been shown to significantly reduce the performance of some heavily-vectorized loads. [7] Patches to mitigate the effects of the vulnerability have also been created as part of the forthcoming version 6.5 release of the Linux kernel. [8]
Opler projected that fourth-generation computer systems would have a writable control store (a small specialized high-speed memory) into which microcode firmware would be loaded. Many software functions would be moved to microcode, and instruction sets could be customized, with different firmware loaded for different instruction sets. [3]
Microsoft has issued update KB936357 to address the errata by microcode update, [25] with no performance penalty. BIOS updates are also available to fix the issue. BIOS updates are also available to fix the issue.
In the context of free and open-source software, proprietary software only available as a binary executable is referred to as a blob or binary blob.The term usually refers to a device driver module loaded into the kernel of an open-source operating system, and is sometimes also applied to code running outside the kernel, such as system firmware images, microcode updates, or userland programs.
The Management Engine is often confused with Intel AMT (Intel Active Management Technology). AMT runs on the ME, but is only available on processors with vPro.AMT gives device owners remote administration of their computer, [5] such as powering it on or off, and reinstalling the operating system.
