I am trying to write context-switching code for a Symmetry under DYNIX.  
I need to have a frame pointer register for use with the stack (similar
to the frame pointer register in a 68000).  I think I should be able to
use the BP register, but I am not sure.  Can anyone help me on this?  The
Symmetry uses an 80386.

Thanks,
	Joel
