SeaBIOS as a Compatibility Support Module (CSM) for Unified Extensible Firmware Interface (UEFI) and Open Virtual Machine Firmware (OVMF) Virtual machine host notification of paravirtualized guests which panic via the pvpanic driver; A patch exists to load the SLIC table from a licensed OEM Windows BIOS. [3] Trusted Platform Module
The UEFI Platform Initialization (PI) specification includes an SMBIOS protocol (EFI_SMBIOS_PROTOCOL) that allows components to submit SMBIOS structures for inclusion, and enables the producer to create the SMBIOS table for a platform. [20] Platform virtualization software can also generate SMBIOS tables for use inside VMs, for instance QEMU. [21]
QEMU does not depend on the presence of graphical output methods on the host system. Instead, it provides access to the guest OS screen via an integrated VNC server. It can also use an emulated serial line without any screen, with applicable operating systems. Simulating multiple CPUs running SMP is possible.
The EFI 1.0 specification defined a UGA (Universal Graphic Adapter) protocol as a way to support graphics features. UEFI did not include UGA and replaced it with GOP (Graphics Output Protocol). [58] UEFI 2.1 defined a "Human Interface Infrastructure" (HII) to manage user input, localized strings, fonts, and forms (in the HTML sense).
Unified Extensible Firmware Interface (UEFI) is a successor to the legacy PC BIOS, aiming to address its technical limitations. [5] UEFI firmware may include legacy BIOS compatibility to maintain compatibility with operating systems and option cards that do not support UEFI native operation.
fwupd is an open-source daemon for managing the installation of firmware updates on Linux-based systems, developed by GNOME maintainer Richard Hughes. [1] It is designed primarily for servicing the Unified Extensible Firmware Interface (UEFI) firmware on supported devices via EFI System Resource Table (ESRT) and UEFI Capsule, which is supported in Linux kernel 4.2 and later.
The Platform Initialization Specification (PI Specification) is a specification published by the Unified EFI Forum that describes the internal interfaces between different parts of computer platform firmware. [1] This allows for more interoperability between firmware components from different sources.
EDK is the abbreviation for EFI Development Kit and is developed by the TianoCore community. [1] TianoCore EDK II is the de facto standard generic UEFI services implementation. [ 2 ]
