the funny thing is that the service manual and the special dimm
installation manual are not quite fiddling the same tune ...

I used a 64-32-64-32-32-32 installation, as proposed by the manual and
lo and behold, after the final 32mb chip, the machine did not boot at
all
The last one I added had been the one of questionable functionality.

So, I ripped it out again and threw it far, far away. And tada, the
machine
works again.

A bit weird really, but well ... at least its working again. One of
these four 32mb chips has always been a trouble-maker.

Well, its OBP 2.25, so that should not have been the problem.

Thanks to both of you and sorry for this long delay to answer, but my
news server seems to be down temporarily.
