6.1 BPI Overview
EVOC BPI (BIOS Programming Interface) is a cross-platform, easy-to-maintain
software interface specification, which supports access to hardware under the
Protected Mode of 32-bit operating system. BPI is a bridge between hardware and
application software, and its purpose is to provide a unified standard interface for the
application layer (in the form of library function, similar to library function of
standard C). With BPI, application software engineer do not need to care about the
specific hardware solution of the motherboard. The users can use BPI library to
rapidly develop their own software products, and when the hardware of the
motherboard is upgraded, there is no need to modify the application software or driver
and the former software can operate on the new platform normally. BPI has greatly
sped up the product development and reduced the maintenance cost. The BPI
architecture is shown in the Figure 1 below:
