AMI uses EFI capsules, you can send any EFI capsule to the firmware as an update, but before it is installed, the firmware will check the signature to ensure that the vendor writes it. The main difference in security is the way that they update, as this is the primary method used in an attempt to compromise firmware.īoth receive updates via the LVFS but differ in the plugin they use. From now on, we'll be talking about the version of coreboot that we build, as, for example, Google's configuration is very different. Is coreboot more secure? The jury is out on this one it depends on who you speak to and how it's configured. For example, the LabTop Mk IV combined with coreboot will deliver approximately 8% more performance and around 20% longer battery life (with a record of 13 hours and 42 minutes for general use). It suits Linux, as it uses the same licensing (GPLv2) as the Linux kernel.ĭue to how lightweight coreboot is, it will offer better performance and lower power consumption. It means you can see everything inside it if you know how you can change anything you like. So which is better? AMI is more capable, but one of the significant coreboot appeals is that it's open-source, so all of the source code is public - you can find it here. You can find all the details of this here.
Configurable options can be changed using our coreboot configurator program, which is available for Linux. The version of edk II it uses has no dedicated interface apart from a simple boot menu. It offers many features, including a graphical interface that allows various settings to be changed.Ĭoreboot, on the other hand, is an open-source project that has only been made available for a finite number of devices (the majority of these being Chromebooks). Which one is better for you depends on your priorities and how you use your laptop.ĪMI is an industry-standard firmware, alongside Insyde and Pheonix. We're making both available because there isn't a definite answer to which one is "better". Since day one, we've used AMI Aptio V firmware for our laptops, and now, we're making a second option available - coreboot.
coreboot uses a standard but bleeding-edge version. UEFI was a direct replacement for BIOS, and whilst UEFI has been standard for over a decade, it's commonly referred to as BIOS.īoth coreboot and AMI use edk II as a payload AMIs version is about 10 years old and highly modified.
The bootloader initialises the hardware, and the payload provides a UEFI platform. There are two main parts of that firmware, the bootloader and the payload. These exist to provide an interface between your Operating System and hardware so the OS know's what devices there are and how to control them. What's the difference? AMI (American Megatrends Inc.) Aptio V and coreboot are both firmware.
