tis not impossible, but requires a developer and plenty of patience and also much more than i even know........
you would need tobe fluent in C/C++, and able to use Assembler,
“AssemblyLanguage for Intel-Based Computers” by Kip R. Irvine*is the great book that gives good knowledge of inner structure of the computer and development in Assembler. You ca also find information about installation, configuration and work with the MASM 6.15 compiler.This link will guide you to the BIOS interrupt list:
