Yes; this is why I was hoping somebody else had done a source pkg :->

Yep, didn't work on my LX164 (went nowhere at all), although the
MILO image was rather smaller than the 2.0 one so I was suspicious
of that...

Hmm. I'm using MILO because when I used SRM I ran into a PALcode
exception problem which somebody suggested was due to a 
hardware bug/interaction with SRM's palcode. Also, I'd much
rather use PALcode for which I have the source...
Any chance of Compaq giving us the SRM console source? :->

Maybe I'll get round to doing something at some point :->
