Check with your system vendor for the appropriate keystrokes or to see if you need to run a program from MS-DOS or Windows to configure your system. Because the settings you make in the BIOS setup program are stored in the nonvolatile RAM of the CMOS chip, the settings are often called CMOS settings. In the following section, we will review the typical setup process, looking at each screen of a typical Pentium-class system.
You can use the inb and outb macros to read and write from these ports to get the entire BIOS settings stored in the CMOS. For the settings memory format stored have a look at: http://bochs.sourceforge.net/techspec/CMOS-reference.txt These mappings are actually vendor dependent, but most of them should be common. Although this is not an API, but with this you can make direct access to the CMOS memory and make your own API.
