Hmmm ... I never played with a DS20, but ISTR that with an Alphaserver 800
we did this to, the firmware (= PALcode) had to be changed when converting
from VMS to Tru64, or vice-versa.
i.e. OpenVMS PALcode != Tru64 PALcode
I remember being surprised about this at the time .... it seems that the
Alpha instruction set is a shape-shifting thing ... or some more subtle
aspect of the microcoded behaviour has to change.
