Are you capable of assembly programming? Basically, you need to 
investigate what BIOS calls are used and how they are used. This 
requires that you replace BIOS calls with your own ones which show 
information about arguments and return values. If you are lucky, you 
might be able to create a virtual environment using Bochs, then you 
won't have to do so much assembly hacking, since you can use GDB in 
some degree.

Probably the cause is that some BIOS calls are not "hooked" correctly. 
Your task would be to find out what is wrong and/or what is missing.
