   Possibly, but at the very least you would have to install a modified   
   $BOOT.IML (it contains a list of compatible model/submodel values among   
   other things).

   No, because the T1 Upg 66 platform is older than the T4 "N". But it may   
   be the other way around - speaking strictly about the (C)BIOS portion.   
   The T4 POST code is a direct evolution of the T3 POST (not surprising   
   since they use the same complex architecture, aside from the cache   
   subsystem and the obvious integration differences).   
      
   I'll need a dump of the flash image to find where exactly the Upg 66   
   fits in the FW family tree.
