A whole lot of nothing. The whole point of the BIOS is to put the system into a state where the OS can be loaded. After the OS is loaded, it takes over control of interfacing with the hardware. On older OSes (*cough*DOS*cough*), the BIOS was a primary tool for basic I/O even in userland applications. You can still do some of that on Windows, but probably only through very low level (ie. assembly) programming.
