UEFI Firmware

UEFI (Unified Extensible Firmware Interface) is a modernized replacement to BIOS (Basic Input/Output System). The specification is maintained by the collaborative non-profit UEFI Forum. UEFI is supported by both recent versions of both Linux and Windows. UEFI firmware with legacy BIOS support has started appearing on Sandybrige (220,420,520,etc.) Thinkpads.
