I've written several lines of code in C in which I am trying to access the OpenBoot CIF to execute an instruction. But immediately after I do the call to the CIF interface address the PROM freezes.

Impossible to say without sources. Perhaps you should compare your CIF code to what SILO, Linux or *BSD are doing.
