Industry consortium (Intel, AMD, ARM, Apple, Microsoft, HP, Dell, AMI, Phoenix) that owns and maintains the UEFI Specification and ACPI Specification. UEFI replaces legacy BIOS as the firmware interface for all modern x86-64, AArch64, and RISC-V platforms. ACPI defines OS-directed power management and hardware configuration via descriptor tables and AML bytecode.

Every modern x86-64 and AArch64 server, workstation, and PC uses UEFI. Required for OS development, bootloader work (GRUB, systemd-boot, shim), Secure Boot policy, and firmware engineering.
ACPI is how every OS discovers hardware topology, manages CPU power states, handles thermal throttling, and receives platform events. Required for kernel, power management, and firmware development on all modern x86/Arm platforms.
