Occasionally a situation will develop where MPI either fails to install correctly or is corrupted in such a way that pkgrm (SVR4), or custom --> remove (SCO) cannot remove the package successfully.

The following procedure will remove MPI from the system manually.

  Remove the Device Drivers

	cd /etc/conf/bin
	
      if ISA or EISA Xi or Xe cards were installed:

	./idinstall -d pcxx
	./idinstall -d pcx1
	
      if Microchannel Xi or Xe cards were installed
	
	./idinstall -d mcxx
	./idinstall -d mcx1
	
      if Xr cards were installed
		
	./idinstall -d pcxr
	./idinstall -d pcr1
	
      if EPC/X C/X or X/em were installed
	
	./idinstall -d epca		[epc(b-h) may exist on some systems]
	./idinstall -d epc1
	
	
 Remove the parts of MPI

	cd /usr/bin
	rm ./mpi ./dpa.Z ./dscreen ./ditty
	
	cd /etc
	rm ./dsinfo ./epcadl ./pcxrdl ./pcxxdl
	rm ./digi/*
	
      for SVR4
	
	cd /usr/include/sys
	rm ./stdigi.h rm ./dgdscr.h
	cd /usr/share/man
	rm ./man1/ditty.1
	rm ./man4/dsinfo.4
	
      for SCO
	
	rm /usr/include/sys/digi.h
	rm /usr/spool/lp/model/dumb.dg
	
 Relink the kernel

	cd /etc/conf/bin
	./idbuild
