I am working with a VaxStation II.  Is there a system call that will let 
a user or superuser perform a write of any specified value to some fixed 
location in physical memory?  What is it?  What physical address would get
written?  If such a system call does not exist, might someone be able
to suggest a way around this?  (a pseudo-device driver maybe?)

Thanks!
