Tru64 on AlphaPC 164 SX ?

Hello Admin Wizards,

after finishing Tru64 5.1b installation on the old 8200, I became kind 
of coltish and I wonder if it is possible to install it on the old 
AlphaPC 164 SX (Processor 21164 PC, Bios 5.62-1) too.

Has anyone in here mastered this challenge?
I tried it with the software bundle I have (Campus License of Tru64 5.1b 
+ Firmware-Update 6.3) but I cant get it to work, obviously because the 
machine does not start with the familiar srm prompf but with an arc 
console (I am not happy with that, but I did not find a possibility yet 
to change it).

I would love to get it running, but it is just for fun - no production 
critical process depends on that. It would just be one machine less 
running MS :o)

thanx and regards
CW
