I should have mentioned that this information was in regard to the P55T2P4,
while you were asking about the XP55T2P4.  There are  some differences.  This
might be one of them.  The ATX version of the board, for example, did not
support 83Mhz (?bus clock) speed.  I apologize for overlooking this and having
to reply to my own message.
