How can you access OpenGL routines on a graphics card through ROM-BIOS Assembly routines? I assume that there is a function number I put in one of the registers when calling 'int 10h' and then the function I require in another register (like VESA and Super VGA functions). Is there a referance to these functions or a web page where I can learn this?

No. The BIOS doesn't have OpenGL support.

If you are writing an operating system (or are using an ancient one that doesn't deserve the name operating system) you can directly access the hardware registers on the graphics card and send it (card specific) commands (for which there usually is no public documentation).

Generaly your best bet to do this is rip apart drivers availiable for the windows or linux operating systems (linux may be easier), figure out the calls made to the hardware, and go from there. While your at it, document your progress though!
