If you send me what you have I can see about re-creating it but a better 
idea might be to emulate the GIDE.

Howard Harte's SuperIO controller is another option and the full CBIOS is 
available, it is extremely similar to the GIDE.

I may have some Big-Board II info around, it used the XEBEC-based 
controller.  In real life many found the Adaptec 4000 series to be better 
since in real life it remapped bad sectors out and there was an RLL version.
