Design And Implementation Of BIOS Based On HP-UX11iV3Operating System

BIOS is a piece of the computer code that is solidified into the ROM chip on themotherboard, it records the most important input and output procedures as well as theinformation needed to set for the system. UEFI (Unified Extensible Firmware Interface) isa detailed description of the standard type of input and output interface. As an intermediatelayer between the user and the computer, operating system links the interfaces betweenhardwares and other softwares. Written in assembly language BIOS age, all the functionsare supposed to meet all the demands of operating systems when it comes to PC as well aswhen the servers desgins the BIOS.With the development of the operating system,especially after the UEFI technology gradually matures, designing a special BIOS for theoperating system has become a new topic.Hewlett-Packard’s HP-UX11iV3operating system is HP’s full64-bit operating systemenvironment that can provide great scalability and high systematical performance to highdemanding applications. In EDKII open source development environment, based on somefeatures adopted by HP-UX11iV3systems, combining the features of standardization,modularity and scalability, when we design BIOS, add HP operating systematic drive andreduce the load of the drive which is unnecessary, thus reducing the start duration. As a result,we can develop a unique BIOS for HP-UX11iV3system to meet its performance needs.Due to adding the HP operating system drive, when loading UEFI on the hardwareplatform, it can accurately load HP-UX11iV3operating system when the system enters theshell. Using UEFI coded by C language, we can help the system acquire affluentself-made function extensions in design of BIOS, and add or delete the correspondingdrives to meet the fundamental requirements software drive needs when the computerstarts. This kind of design can load HP-UX11iV3more stably and quickly, promoting abetter application at the enterprise level.
