Allegro C3600 boot woes, faulty DIMM likely.

OK, so the "announced" Allegro C3600 has finally arrived- has nice two
9GB Seagates, FXE graphics and additional UW SCSI board.

When it was sold to me, it was said not to have memory, what was
indicated at boot-up ("no memory found" on LCD). I was surprised to
discover though that there was 1 GB (?) DIMM in wrong socket. After
moving it to first one, the machine now halts with "dup entry in PDT"-
which might indicate that the DIMM is in deed faulty (or- how to check
further?).

What really bugs me that it doesn't output anything on either graphical
console, nor serial port. Is that normal?
I know that my B132L pulls out console pretty late too.
