UEFI pre-boot guidelines

As computer technology has advanced, the BIOS has expanded to handle new components, larger and more complex chipsets, add-in cards, and other enhancements. This expansion has made the BIOS increasingly intricate. Development of the Unified Extensible Firmware Interface (UEFI ) is the computer industry’s solution to BIOS limitations. UEFI is a set of modular interfaces that replaces the set of traditional BIOS interfaces between the OS and platform firmware.

UEFI is derived from high-level C language and is driver-based, scalable, and easy to debug and upgrade. UEFI uses a modular, platform-independent architecture that can perform boot and other BIOS functions. HP employs this technology to implement an UEFI partition on all of its business notebook and desktop computers.1 Along with replacing the traditional BIOS interface, the HP UEFI partition adds tools to the pre-boot system environment.

The HP UEFI partition is viewable on the hard drive, labeled as HP_TOOLS. Starting with 2008, HP business notebook and desktop platforms that included the UEFI BIOS, HP created the UEFI partition as a FAT32 primary partition, due to UEFI limitations with accessing other partition formats. These guidelines include specifications for the Microsoft® Windows® 8 operating system (OS).
