Need Solaris drivers for old hardware

 (Hi folks, I posted this question yesterday, but I really should have mentioned the platform in the subject line, as people will assume Windows.  I didn't see a way to edit the subject of an existing topic, so I'm re-posting this.  I apologize for the mostly-redundant post.)

  I'm looking for the driver package for the Solaris 2.x OS for SPARC systems (not x86, and certainly not Windows) for the PCI-MXI-2 board.  I am trying to resurrect an old data acquisition system mainly for fun.  I can't seem to find those old drivers anywhere; can anyone point me in the right direction?

                        Thanks,
