Any image can be used that does not break any copyrights or regulations, but must adhere to supported specifications for the unit. Initializes Intel silicon.īootsplash – public – Splash screen image when the device boots. Microcode – public – translates micro operational architecture and CPU state into machine instructions.įSP – public – Firmware Support Package. The descriptor is not public but because it does not contain any code the distribution is not restricted. ME firmware – Intel proprietary – an embedded coprocessor on some Intel processors that requires ME firmware to run.įlash descriptor – not public – 4KB data structure on modern Intel platforms. The blobs are listed below and are summarized in the following table. To successfully build coreboot for the VP4600 series, access to Intel blobs is required. As such, some Intel blobs are NOT included with the distribution of this source code and build instructions as Protectli does not have the rights to redistribute Intel proprietary blobs. Intel blobs are proprietary and some are only available to licensed users. These modules are referred to as “blobs”. In addition to the source code, there are binary modules that are also required. In order to expedite the availability of the source code to the general public, Protectli has devised a “build_coreboot” repository to expedite the release of the source code. This creates a long delay between the release of a product and the availability of coreboot binary and the source code to the general public. coreboot has an official “upstream” approval process, however, it requires a lot of time to process. A list of supported platforms can be found in the table at the bottom of this article.Īs an open source project, it is important to make code available for inspection and building. This article describes how to build and flash coreboot using the Vault Pro VP4630 as an example. More information on the security aspects of UEFI coreboot on Protectli Vault Pro 4600 series can be found in the Knowledge base article at this link coreboot Security Features. The coreboot home page can be found at this link coreboot. Coreboot is an open source firmware project that can be used as an alternative BIOS that provides a faster and more secure booting process.
