Wikipedia: Extensible Firmware Interface

Wikipedia entry on EFI:

The Extensible Firmware Interface (EFI) is an updated BIOS specification developed by Intel. Designed for use with trusted computing, it allows vendors to create drivers which cannot be reverse engineered. It also allows operating systems to run in a sandbox, delegating networking and memory management to the firmware. Hardware access is converted to calls to the EFI drivers
