5.1 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 the 32-bit operating system. As a link between hardware and
software, the function of BPI is to provide a standard interface (in the form of library
function, similar to library function of standard C) of platform-irrelevant operating
hardware for the application layer, therefore, application software engineer does not
need to worry about specific hardware solution for the motherboard. Users can rapidly
develop their own software products by using BPI library, and when the hardware of
the motherboard is upgraded, there is no need to modify the application software and
the former software can operate on the new platform normally. It has greatly sped up
the product development and reduced the maintenance cost. The BPI structure is
shown in the Figure 1 below:
