![]() ![]() But development efforts were transitioned to our Aptio UEFI BIOS years ago, and AMI has not actively supported AMIBIOS development since the introduction of our UEFI firmware. No doubt there are some legacy AMIBIOS products, particularly embedded systems, that are still in use in the wild as AMI had a strong market share for BIOS since 1985. What does it mean for AMI?ĪMI made the transition from legacy BIOS to UEFI years ago, with the release of the first generation of our Aptio® UEFI BIOS Firmware in the early 2000s. Therefore, removing it will lead to more secure computing platforms – which was one of the key driving factors behind the creation of UEFI in the first place.Īdditionally, saying goodbye to CSM and legacy BIOS on new 64-bit processors will speed development time, since compatibility with CSM will no longer have to be added and tested during the development process. ![]() ![]() #American megatrends bios update legacy code#With respect to security, leaving CSM in UEFI firmware exposed certain security holes where malicious code could potentially gain low-level access to a computer system. One of the problems of CSM, however, was that many of the features that UEFI offered had no equivalent function or support in legacy BIOS, so CSM became gradually more limited in what it could do. While there are any number of reasons behind this announcement, which many saw as a long time coming, we can focus in on two of the biggest: security and ease of development.įor years there was a “Compatibility Support Mode”, or CSM, that enabled a newer, UEFI-enabled system to operate in legacy BIOS mode. Last week, many major tech media outlets like ZDNet, Ars Technica, AnandTech and others covered news of Intel’s announcement that it would phase out support for legacy BIOS on 64-bit platforms by 2020.Īs a key partner with Intel in both legacy BIOS and UEFI for many years, we offer up our thoughts and observations here, along with a brief discussion of what the potential impact is – both for AMI and for end users of computer systems that still retain legacy BIOS support.
